In this video, i teardown a nag1 in a Jeep that has a noise when drive or reverse is selected, iii let you hear the noise before the trans get pulled out. Noise ended up being a stripped pump stator where it fits into the converter. Since there is no Dipstick, i talk about the measuring tools, for the 722.6, the part number is 1401521. At the end i go over whats inside the valvebody. Thanks for watching

I had a Grand Cherokee come in with this exact problem about 5 years ago. I figured it was a very unusual failure based on how difficult it was to get parts through Chrysler at the time. Good job on the video - now I have something to show people to describe the weirdest 'WOOP' I've ever heard.

I have the W5A580 TX in 3.7 WK with over 100k no issue, Long Island stop and go driving with cold weather is really hard on TX and drivetrain, one of the biggest reasons TX fail is dirty oil, blocked filter, low oil from leak, heavy towing without additional cooling. Initial change with this TX should be 24-30k or 2 years as there will be more debris from break-in, then I prefer 30k or 3 years for heavy stop and go and 50k or 5 years for light stop and go. Keep in mind only half the oil comes out with pan drop 4-6 Qts., total capacity is approx. 10 Qts., what they call a filter is really a screen unlike engine oil filter, this is to maintain high oil flow at the expense of unfiltered oil.

Awesome video! Here a bullet proved idea, if someone comes again with a Wrangler: Put in carbon clutch and the stronger torque converter from the AMG G-Class or AMG SL55. We in Germany drove 2.8 Diesel Engines in the Jeep. With torque over 550Nm we kill the torque converters an clutches very fast. Chrysler built the same small things (cheap) in every model of the wrangler. Only Chrysler 300 Hemi Must have the stronger parts I think! 👋👍

CVT you must change that fluid very frequently, DO NOT listen to this lifetime fluid bullshit with any transmission, at a MINIMUM, do drain and fills every 60k, every 30k with a CVT and simply measure what you take out and replace the same amount plus a few ounces. If you have a leak, take to a shop. Drop the pan at 60k to change the filter. On my JKU, I swap out a couple quarts of ATF+4 with every oil change, I ALWAYS use OEM ATF, Especially if under warranty.

I stopped at a light with zero issues and when I took my foot off the brake it made the exact sound heard in your video. I had no codes and no shutter. The motor didn't even bog down when it happened. I found no remanence of the missing splines either. It looks like they just wore out unless they're still in my torque converter. Did you find any bits anywhere during your teardown? Any input is appreciated, I'd like to keep it from happening in the future. Thank you for the video, I was a huge help.

Got a weird question. Nag1 with 156k miles. Torque converter is 3 years old with 32k on it. Trans fluid D&F done every 45k miles, just dropped the pan 4k miles ago and did the filter. No debris came with fluid. At Idle in D, im getting a revolving whirring sound. Its ONLY in drive, goes away the second I hit the gas. And it only happens after driving for about 20 or so minutes. If i hear it and put the car in N/P/R, no sound. Back in D, itll start up it isnt instant. Itll make a whirr, whirr, even out, than begin whirring constantly with the engine RPM. when I shut the car off its the LAST sound I hear. I cannot find anyone whos having this issue and everyone says due to dirty fluid/clogged filter yet it made the sound both before my fluid swap and after.

@GaryFerraro Жыл бұрын

Wondering if something in the PCV, With the car running did you take off the oil fill cap to see if noise goes away? If it is a filter noise, you would hear it in every gear. If it is a converter noise you would hear a noise in Reverse and Drive ranges and it would go away in park and Neutral

I ran across your teardown of Nag1 5spd doing research on my nag1. I have a 07 300c rwd i just installed another 5.7 in due to other 5.7 overheating and droppin valve seats. When i was done with install i filled my trans back up with fluid because i installed a 3k FTI stall converter in. Trans had no prior problems shift and drove as should, so i shifted into drive no go, when i shift into Reverse no go. I dont have any trans trouble codes no noise trans literally does nothing. I overfilled trans and fluid everywhere smh so i siphoned it out down to correct level and still no movement. What could it possibly be? Im familiar with small teardown like changing solenoids and conductor plate. Im thinking the conductor plate got too hot due to me driving with hole in radiator and sending it 5.7 heaven since i know radiator also trans cooler no coolant no trans cooler smh so if you know what it is i would really appreciate it.

Is it just because of the amount of miles that are one it?--- or just because you are already in there, and might as well get some new parts, because of the 100k miles?---- or is it because you'll have to warranty it, so you want to cover your tracks??
