I'm not sure if you read the comments but you are incredible. Like the Einstein of transmissions. Love watching your videos

Nice! Always fun to watch and to see how the different trans are made.

You are a champion 🙂

you showed me enough to get in trouble esse lol

Pleasure to have the privilege to see a true tradesman do this very meticulous trade ,, experience and confidence show and ya are a great thorough teacher 😀 fine work dude

Thanks Hiram, another awesome video, your the best! Much appreciated you sharing your knowledge with us KZfaqr's

@ 2:05 Somebody's definitely opened that thing up before you Hiram. I worked at a GM dealsrship for 6 years and I've NEVER seen a SRTA unit come from GM with silicone on it anywhere.

Hiram you are an excellent technician. It shows by the way you take extra effort to make sure things are correct and your attention to details.

Me gustaría ver éste video pero en español, mi amigo aprendo mucho con sus videos, Dios lo bendiga mucho

Awesome. Had to go a extra step further with making a mess but your advice for sure got the job done with replacing the seal.

Awesome video. Looks like I'll be replacing the shift solenoids!

Saludos, hay alguna posibilidad de hacer una versión en español de esta caja o agregarle subtítulos a este vídeo porque de donde soy no hay especialistas en cajas electrónicas. Gracias por este vídeo.

Thanks for sharing another great transmission video. I always look forward to your teardown/inspection vids, and the common failure tips.

If there was a Batman for transmission-Gotham city, you would be it!

I bought a 2010 cobalt at the auction a few years ago it was listed as a transmission problem. When I drove it to my shop there was a noticeable shutter that most people would think was a torque converter. I put on the lift and noticed a new torque converter, axle seals, case gasket and a new Tcm so I thought man it looks like it was rebuilt. There were no codes so when I drove the car I seen that the converter wasn’t slipping so I looked at the fuel trims and noticed it was running lean when it did the shutter. I found the mass air sensor was dirty, air filter was packed with dirt. Put a new air filter in and cleaned mass air and problem fixed. That customer spent thousands of dollars on a rebuild and tcm but it needed a 10 dollar air filter and clean the mass air. Lots of customers don’t want to pay for diagnostic fees but when you bring your car to a quality shop like mine who can properly diagnose your car yeah ur paying for a diagnostic but I will save you money by fixing the problem not guessing or throwing parts at it.

Common issue with one if the tube within the trans feed pipe, breaking loose & loosing forward gears. I was surprised to not see u inspect the feed pipes!!!

I am rebuilding a 4T45E out of 2007 Saturn ION. I got a Transtar rebuilt kit when measuring all new and old clutches stacked side by side my new clutches 30 thousands thinner. Only one kit available. I went to dealer same thing.

Hi, Hiram Gutierrez, your video is very interesting and helpful we appreciate a lot your video and we hope that you continue doing another videos of Automatic transmission 4T40-E. Thank you.

Gracias! Por este video Hiram. En mi país Venezuela tenemos muchos Cavalier con esta transmisión como no tienen la varilla de chequeo aceite toda terminan dañandose prematuramente.

actually this is the best and only video I could find on KZfaq for the 4T40E transmission .. I recently lost all forward gears I only have reverse this is definitely right out of the Generals mouth. the shift solenoid gets destroyed from Heat and to check your forward gears but I probably going to have to buy a used transmission and have someone redo it.thanks ...

gracias por la respuesta a mi consulta ,voy a cambiar esos selenoides a ver si Se compone ,buenos dias..

Deberías subir ahora de como armarlo, para ver si de verdad se soluciona el problema. Gracias

Tremendo video!

@Automatic Transmission Do you need the fluid pump running when checking the level using the check plug on this transmission?

thank you for the video. and to think that is what makes my car go.

wish you would drop hints of what happens when certain parts breaks

THANK YOU SO MUCH! Finally I know whats inside my daewoo lanos transmission! I couldn't find it anywhere else! :) Thumbs up!

i have that exact transmission. i have an error code P0742 I replaced the TCC sensor, the wire harness thats from the transmission cable to the firewall, and the ECU computer.. and i Still have the Error code, i erased the copmputer..drove it on the freeway..and after a while still got the code... TCC stuck on... Any help on solving this..someone told me clean the TCC valve with a metal brush, but i dont know how exactly.. I used new oil and sea foam,, and still keep getting this error.. Any Help is appreciated as i do like my lil hatchback and its my daily driver and low on funds, so im doing everything my self...

Great video, but I was wondering if you could help me. I was finishing tightening down the last bold of the side case after changing some solenoids and heard a pop. Then I looked at my axle seal and there is a spring stuck in between the seal and axle about the thickness of the "manual valve link". What could this be? I have a photo of it as well. Thanks.

Excelente trabajo mi estimado Ing. Saludos desde Monterrey, Nuevo León. México.

From one gearman to another, good video

This was excellent.

Eres Muy professional hirian gracias por compartir Tus videos

How are you dear. I have a 2008 Cobalt with a 2.2 engine and an automatic transmission. There is a problem: when I start driving the car, the transmission gear becomes hard shift after driving for 5 minutes. and then When I turn off the car and restart it and drive it again, the transmission becomes normal and smooth shift. But after continuing to drive the car for 10 minutes, the transmission returns to becoming hard shift , knowing that there is a code p1811( maximum adapt and long shift). what do you think about this problem?

Great professional approach

Muy buenas noches exelente video como siempre. Va a subir el rebuild de esta transmisión gracias.

That you so much God bless you you made the best vidio for any one wanting to try this and you do great job fast but you explane so much i asked God to help me and he did he hade you do this how to vidio so detailed gave me confidence to go at mine i realy couldent aford a new trans and i realy dident want a bone yard it shifted hard one day at 200000 miles little less and id rather try to just fix my trans istead of going threw bone yard trans

do the differentials ever go bad? should they be clunking in one direction?

Buen video. El unico problema de esa trans.es el alto costo de las herramientas especializadas .Saludos.

AMIGO HIRAN UNA PREGUNTA SI SE DAÑA EL SOLENOIDE DE CONTROL DE PRESIÓN QUE USTED NOMBRA AL PRINCIPIO, ES POSIBLE QUE LA CAJA NO APLIQUE?

I had same trans n when changed filter there was a black shim in the pan but I don't see one in your tear down.

When you know that you have to change the torque converter of that transmission, mine is defective and I do not know if it is necessary to change the entire transmission or only the torque converter?

Excelente vídeo gracias por compartir su buen trabajo Hiram.... Yo tengo una pregunta y me sería de mucha alluda si me la pudiera contestar Mi carro vibra en primera y segunda cuando aceleró Tercera cuarta y reversa trabajan sin problemas Después de 10 o 15 minutos el carro ya no avanza .... Tiene alguna idea de cuál sería el problema ???

Buenos los videos podrias poner uno bilingue de esa transsmicion

Good to see you wearing gloves Gutierrez , keep em on from now on :)

excelente video,gracias de antemano,tengo un problema y necesito de su ayuda y conocimientos .en dos ocasiones he reparado una 4t45e por problema en la reversa y poniéndole todo nuevo ,no he podido ver donde esta el gran problema, si pudieras ayudar te lo agradecería ,gracias nuevamente,espero respuesta .

Maybe you can help me out....I have a 4T45E Trans in a 2006 Cobalt..... on the TCC Lockup Solenoid that goes in the Valve Body When I took mine off the inside went flying..now I'm not sure if that little spring goes in the middle then that little shaft..or the little spring goes in the Valve body 1st then the shaft, then the sensor...Any help would really be appreciated..Is it Solenoid... then Spring.... then little shaft.. .or is it Solenoid.... then Shaft...then spring....Thanks for any help Jim

I have a 4T45 and I get the code P0974 for the Shift Solenoid A Control Circuit High, you mentioned checking the resistance in the solenoid. Do you recommend through the harness or right on the solenoid?

12:30 That hook tool is only found in well seasoned garages.

What type of trans does a 04 chevy classic 2.2 ecotec have?

I replaced all solenoids and now everything is drive except for park any idea of what this could be?

Hiram.... excelente video de la 4t40.... me gustaria, si es posible nos enseñes las pruebas para la funcionabilidad de los sensores y el desarme del cuerpo de valvulas de esta transmision... y si pudieras en español, genial.... yo tengo un z24 y acabo de desarmar mi transmision...

Can you tell me how to reconnect the manuel valve latchet? Gravity keeps telling me no.

Tiene algún video de como probar el switch negro que esta colocado en la parte trasera de la transmisión. Mil Gracias

buenas compañero excelente su demostración al chequear esa caja automática en tan pocos minutos! quería comentarle un caso mio en particular yo tengo un cavalier del año 98 con ese mismo modelo de caja tuve un problema y le entro agua la mande a chequear la revisaron le hicieron servicio a la turbina igualmente a la caja pero al montar igual siguió padeciendo del mismo problema sigue con un sonido como de engranaje, piñón o algo por el estilo mi mecánico o el que hizo el trabajo chequeo las piezas y me dijo que estaba bien! que me puede decir usted o que orientación me puede dar al respecto, agradezco su opinión! saludos! excelente video

Great video!! i wish you could put one out every day.

thanks for the video,hiram.hopefully i can find out why i have no reverse.

***SERVICE NOTICE*** on torque converters.GM front wheel drive cars. Seems many torque converters,are being returned for a refund.And are the core, from the replacement.And are being recirculaed back into the rebuild stock,many are in need of extra double inspection,(are are not rebuilt) but old cores, appearing unused, on the outer shell.Look for the ,double welds,and shiney Stainless.Sprag bearing with no discoloration.inside.

What converter brand did you use on this rebuild?

hola. gracias por el vídeo esta muy bueno y la verdad llegue a el buscando información de una falla de mi caja automática es un cavalier año 96 2.4 el cual no pasa tercera ni cuarta en D y si paso de forma manual tampoco pesca la tercer. la primera y la segunda y la reversa funcionan bien. me preguntaba si me puedes orientar cual puede ser la falla. muchas gracias

+Hiram Gutierrez how do you install the forward band? i do not know the position of the band or how to install the forward clutch assembly on the automatic transmission. The assembly gets stuck on the band because the band is closed too tight if i install the band first.

working on one of these on a saturn l 3.0 has code p0742, and has this noise like a bad power steering pump would sound like cant figure out the noise revers doesnt really work unless you give it gas

i like you new channel great video keep up the good work

I have a 4t45e it takes about 20 seconds to go into 1st when I put it into drive and sometimes longer when it's cold. Suggestions?

Is there a transmission fluid over fill....tube ? I added transmission fluid a bit too much

When you take these apart, what usually goes bad? The fluid valves cracking and not enough pressure? Do clutches really get worn out in the every day transmission? I got a 4T45E and its shifting hard, i almost think the inside will look brand new and its just a cracked valve line or a melted solenoid. Then again I dont know much about this stuff, just seems to be the overall theme

Thanks for sharing all the tranny videos, I've learned a lot watching your videos. You're like the transmission guru. Thanks.

Hello Hiram : I am very pleased to see this type of videos, great job ! I am curious to know if you have one on a GM Oldsmobile 88 Royale with a 4T60E transaxle, recently the transmission cooler was leaking fluid into the radiator ,around the pressure line hook up to the cooler on the radiator side where there was a flat rubber washer that was split in the middle, causing a lost of fluid and overheating of the tranny.I replaced the radiator.I was advised to flush the converter as well as replaced filter and fluid. When flushing the tc, I ran out of dextron oil and added some mercom Ford type that I had, when I installed the filter I couldn't get the old O ring sleeve that holds the filter in place against the valve body, so I installed the aftermarket filter leaving the original gm bushing or O ring in there so as not to damaged the bore trying to pull it out . I don't think it was a perfect fit.Now I have to wait for the tranny to warm for about 20 minutes or so, before it goes into gear, Sometimes if the car sits on a rolling hill and I let it rolled back in reverse it would engage into reverse and forward,with no problems, Once is warm the vehicle runs great it shifts fine, But after is sitting for hours it would do the same. I am seeking some advise if you have the time, Also the throttle body positioner sensor is disconnected now because is acting up reving to high, Don't know if it should have a tab where it connects to the throttle plate shaft , I don't see it there. Called GM but is discontinued. Why is it not priming or loosing pressure, Thanks for you help and input Any insight on this issue would be very much appreciated .Keep up the good work, Reinaldo.

The inner sleeve axle seal is there an easy way to get that off without pulling the transmission? Is that a sub axle that can be pulled out and then replaced?

how would you change out the differental bushing on the tail end of it? very common problem axle play.

Saludos Hiram yo tengo un chevrolet cavalier 1999 2.2L tengo que comprar el Torque Converter Clutch Solenoid y me preguntaron cual es el modelo de mi transmisión y en realidad e buscado donde lo dice y no lo e encontrado se que viene ese 4T40-E y otro no me acuerdo el modelo. Y como se si mi transmisión es 4 velocidades o 3 gracias de ante mano y muy buen video.

Great stuff...thanks for sharing your knowledge.

amigo como mido la presion de aceite de este tipo de cajas..

Marc Garza Can you make a video of a total rebuild of a 4t40e. I would also like to thank you for all your vids, they have helped me out alot.

I have a 4T40-E with differential problem. The output shaft (on the passenger side of the car) deep inside ... is missing. I'm trying to figure out how to proceed. Do you have any videos looking at a differential?

Question how important is the plastic washer on the cover at the axle shafts hole?

Another great video Hiram. :) Tell me is it not better at this point not to just throw a soft kit in it whilst it's apart? Do you see a lot of these units with broken flywheel damage? I can't believe they didn't burn that unit right out...

Almost seems like the gear train and friction/band layout on this is the same as on a 4R75W.

Brother I would like to see a reassembly of the 4t40e transmission if so possible please! Great videos! Thanks! God bless!

Fantastic. Well done my good man.

Te felicito amigo Hiram ... Muy importante el video.... casualmente e desarmado la mia porque no aplica el retroceso.. cual podria ser la falla ?.... un detalle que pude apreciar en el video es que no pude ver el filtro q pudo haber pasado?.. I congratulate friend Hiram ... Very important video. ... casually and disarmed mine because it applies the reverse .. which could be the fault?.... a detail I could see in the video is that I could not see the filter q could have happened?

Obviously you are an expert. Sometimes the audio was not too good. Could you please show us what a bad band looks like? Thanks for this video.

Absolutely amazing !!!!

Do the trans have to come out to put in input sensor in

How would you say this compares in terms of gear options and other aspects when looking at the CD4E? I know they are different makes but I would say unless these work better somehow then the CD4E is better, ignoring the non serviceable filter

Do you have to have a special tool to press in the axle sleeve.

Thank you for this review! Can you tell me if I can convert this one or the 45 to 4WD? TY.

Good video, it was easy 2 follow along

I have the same transmission in my 2009 chevy Malibu it pull and it reverse but it won't shift out first gear when driving please help me it just started doing that yesterday

Great video brother!!! That’s the same transmission that I have in my 2006 g6 and we didn’t know it but ran it dry of fluid and it started slipping and hesitating take off! The pan was what was leaking so I bought a new one. Do u think that it would be ok to just put fluid in it and see what it does or what? Thanks

Any recommendations for a pressure switch, manifold, and shift solenoid kit?

Where is the valve body located on this transmission

Great video! I have a 4T45e in my 2006 Chevy Malibu 2.2L which won't shift into 4th gear. It has 154,000 miles on it. The fluid color looks and feels good, but it's obviously not new. It doesn't smell burnt and the level is good. I bought this car at an auction. From what I have seen online, the no-shift condition is likely caused by a failed 3-4 shift solenoid. I plan to replace it myself, maybe next week, but I don't have a garage or a vehicle lift, only a hydraulic floor jack and jack stands. Is the takedown exactly like the 4T40e? What else should I replace while I'm in there? I have another car to drive and will decide later which one to sell and which one to keep. Also, is it possible to do the job without removing the transmission? I sure wish that I knew what you know about transmissions.

Is the 4T45E transmission the same? What are the differences?

I Watched this Utube video 20 times.

How did you install the torque converter

Hey, got a few questions for you. First off, I was given an 01 Saturn L200 from a family member because the transmission slips in all gears very badly. It has the 4T40-E transmission in it. When it was first purchased, it worked fine, then it started slipping in all gears, (trans pan leaks fluid from the gasket) it was sent to a shop and I'm assuming they just topped off the fluid and it worked perfectly fine for a good while, then started slipping very badly again in all gears, and they drove it this way for about 20,000 miles.(idiot niece) Now, if it were really the clutches slipping that badly, how in the heck would it last that long? could this transmission just really be low on fluid and or have solenoid problems at the same time? When I say this thing slipped badly, I mean it was damn near redline to get it to take off in all gears, 1, 2, 3, R. But, when the shop did whatever they did to it, it worked perfect until I'm assuming the fluid level got low again. It doesn't leak fast, just very slow drips.

is this transmission the one of the 2003 grand am gt ???

Is there a specific name for the pump

Thanks for a great video
