I had a transmission not go into overdrive because of low voltage and after replacing the alternator it went to shifting right once more also the low voltage cause several other things to not function correctly. So change the alternator before you try to replace anything else.

yea weird beard already told us about it.

Change the alternator first !!! Then check it for codes.

I love seeing these haters on here, all the man is doing is buying otherwise dead cars, bringing them back to life for others to enjoy at a great value. Maybe he makes a few bucks or loses a little. And then KZfaq pays him to document the whole experience for us to enjoy love/hate. The man is doing what he loves!

Holy crap you scored, I like that Generation more than the 2nd/Refresh Model

hope to see you cleaning the headlight :)

Randy, change the alternator out first. The computer systems in that car is not getting enough power. This can cause a lot of problems. Change it out charge the battery and drive it again. Hope this helps. Hope you have a great day

YOU FINALLY GOT A TOYOTA!!!!! Thats the white whale of Copart, usually sooooooo overpriced.

Funny, you said GM knock sensors are easier but every LS/LQ guy in here knows where those are. Under the manifold.

Sold a clean 1999 RX300 AWD last year with 250,000mi for $3250.

Hey randy try and give the alternator a tap with a hammer 🔨 sometimes that will make it start working . Get a yard alternator , around my area they are $45 to $65

that looks pretty clean not gonna lie

The first-generation RX300 we're over built like the Land Cruiser. Designed to last a minimum of 25 years. We had a customer come in looking for a replacement for his RX after the transfer case locked up at 483k. The transfer case made it that far on it's original fluid. If it wasn't for the interior being completely worn out he would have had it repaired.

Nice Lexus Randy! That front license plate represents crossed cannons that are the symbol of the US Army Field Artillery that is based at Fort Sill in Lawton, Oklahoma. I was stationed there from 1975 to 1977. Good luck, Jim (Retired US Army) in Florida

Had one of these! Super comfortable and reliable as all hell. Congrats on the purchase!

A family member put 328,000 miles on hers before driving it through a fence. These are Japanese made cars that stand the test of time. You scored!

Your home owners association must love you! All those cars parked out front and you doing constant repairs in your driveway and the street I’m sure has made a lot of friends.

Great video to wake up to. Good luck on the suv

Replace the alternator first! Most likely it’s low voltage causing the overdrive not to engage.

This is the kind of content I love. Finding a solution to a problem. I hope you do the job and film it.

That's and electronic control transmission If the alternator is not putting out the right amount of voltage the transmission won't function properly

1300 for a Lexus...good buy. These are excelent vehicles

your Instagram is almost like secret inside scoop

Good Job Tim! Best of Luck on more to come.

If the Timing belt and haven’t been been replaced, it would be a good time to do it. Hopefully the previous owner recently serviced that.

Great find. You’ll figure it out. Love the channel Randy. ✌️

Great purchase Randy, I always loved this version of the RX, going back to the late 90s

Good buy in the Lexus. Looking forward to seeing the knock sensor replacement video.

Looks like another good buy. Really enjoy your video's. Nice to see an everyday guy and his family and friends doing what you do. I'm subscribed to several other channels, but they don't have the same "regular guy" feel to them. They all just throw money at things and make the video's more about them. You, Weird Beard, Monkey Wrench Mike, and TJ's Auto, top rate! Keep it up!

Great purchase Randy!!! What year is it? They hold their value here in Texas. Looking forward to next video.

Randy it doesn’t need an alternator the battery light pops up when you put a jumper pack happened to my 1998 Lexus sc400 just needed a new battery

Randy there is push button on the Shifter.that overdrive.

Yep sounds about right moms 1994 V6 LE Camry has the same issue I think it has a bad knock sensor too but has no other issues

Keep up the great work thanks for the awesome content

I was bidding against you on this one Randy. I went last Friday and checked it out and loved it. I set my top dollar at $800. So someone pushed you up over $1K but even with the new alternator, that will be a good buy. Just a hobby for me so I really picky on which ones I want to get involved with from there. Look forward to seeing how much you end up getting for it.

The Lexus RX300 is the most influential automobile design ever. Every other car company has copied the RX300 design. This car is as important as the Model T. And it was 2 decades ahead of its time.

you can test the alternator with the jumper pack. hook the jumper pack .start the car up. than press and hold the red button on the jumper pack. IF voltage is 14 or higher is good if not you know.

The knock sensor went out on a V6 '91 Toyota 4Runner that I was working on for a family member. I drilled a hole in the engine lift bracket and mounted the knock sensor to the lift mount. Enough vibration to fake out the computer. Vibration of the knock sensor causes a small amount of voltage that indicates to the computer that the sensor is o.k. I spliced a new line into the ECU for the knock sensor. No need to remove the heads.

Those old RX’s are tanks. They will go forever

Nice one Randy, that's an easy flip. Love it.

Felicidades Randy!!!!!! Great Job.

Ha Randy it’s Ronald love seeing your dog it’s so friendly and social and loves being in the show,not like your brother he looks like he is doing Community service, any way keep up the good work

Hi Randy. Great deal. Lexus=Toyota, Awsome!! Alternator= easy fix. Knock sensor, intake manifold removals not that difficult. I love those type of jobs. Gravy, for me anyways. Its what i do. Still a terrific deal! Rev. Great video!

What year is this

Check the alternator brushes before replacing the whole alternator. Maybe new alternator brushes will fix the alternator.

Not first but still stoked! That's a fine looking Lexus Randy

Awesome! Randy, please consider one of those cameras with a suction cup mount so when driving we could have a nice angle to the front of the cabin 👍 Keep up the good work and greetings from Europe 🇪🇺

How do the fees break down?

i like the vids your doing a good keep up the good work

I bet if you polished up the headlights and taillights you could get maybe 5500$!

For those who worry that Auto Auction Rebuilds doesn't rebuild sounds like their worries will soon be over. Hope the repairs go easily if the Lexus needs them. One heck of a deal even with the repairs.

Kepp up the great work

Looks like you found a winner Randy. It cracks me up when people comment about you losing on flips...lol But when you hit consecutive wins it sounds like crickets in here....lol

Can't trust those engine codes until you have proper voltage in the system. It'd be good of JNC to send you a lithium jump starter for shout outs so you didn't have to drag that concrete block all around the salvage yard.

hello first change alternator before touching knock sensors, it could have been that the car was ran until battery was low caused codes and misfiring. Charge battery and erase the codes and try driving it again

Amazing find Randy. 👍🏻👍🏻👍🏻

awesome find randy!

Those MAF sensors never go bad, you just have to clean them, the filaments get coated with crap, dont be scared to spray them hard and close, they wont break.

Dedar Randy, It would have been nice to see on this video you checking the codes and also checking the voltage output of the alternator.

Looks like a 1mz-fe but with vvti. Altenator in my 95 es was bad after 178000 miles, and check engine light was egr valve membrane and second lambda sensor. Besides that its rock solid. Great choice :)

Cool 😀 Will be interesting video's seeing you fix it.

be nice to see some work being done by you and Mike and I think that you got a good deal

The knock sensor is going to be difficult because a lot of the bolts are hard to get to (one on the back of the plenum). Might as well change the back spark plugs/ ignition coils while the plenum is off because they are back there too. Just did the exact same repair and it can be done in 5 hours or so but it is very frustrating. Make sure to get a new knock sensor wiring loom because that might be the problem (the plastic coating suffers because of the heat of being that close to the engine).

Time to get those headlights shined up and the mobile mechanic over here to get working on it!

What's an Overdrive?

I had a Lexus do the same thing . knock sensors causes the problem with the overdrive. Don’t you just love to have to pull the intake off.

Outstanding

It's a steal! Good job Randy.

Stop with the negativity!! YOU CAN do all this and it’ll make great content in the process. When you’re finished, the sense of accomplishment and satisfaction will be there, bigger than ever!! Looking forward to seeing it happen!

Very nice find Sir!

What does Overdrive Means ?

Have a 2001 Highlander, practically the same as this one, Identical issue of not shifting due to a bad knock sensor, i saw a video and jumped the bank one with the bank 2 sensor and the CEL is gone and it drives fine, This thou is just a temporary fix till i pull time to get the plenum off and install a new sensor. The Knock sensor wire harness comes out on the right towards the drivers side and connects into a plug just like an O2 sensor. If the codes are cleared it will drive just fine for a few kms and then trigger the CEL, after a few kms will not shift to overdrive. Good luck.,

This is Ronald from Nsw Australia love all the shows about time you and weird beard did more like a c7corvett or Lamborghini you can do it stop with the small stuff you are better you deserve it

Check the knock sensor wires with a fine tooth comb

Nice pickup Randy IMO Definitely due the alt before pulling the motor apart ,could just be voltage issues on the Tran's 💯 Salute 🙌✊😎.

Great buy Randy 👍🏼

Great deal , i love the SUV , its a solid cars , when i saw it in your video i was sure that you will bid on it , good purchase.

Did you sell your grey harley truck

I Iike the clean titles you have been getting lately

Randy Dunn engine in that vehicle is a good engine my Toyota Avalon has that same engine in the old Toyota SR5 pickup trucks had that engine that's Old School Technology are good good engines as far as I heard

It's funny mike tells us what's coming on your channel and you tell us what's coming on his lol Randy KEEP UP THE GOOD WORK GREAT VIDS ENJOY BEING ABLE TO "SEE" WHAT YOU ARE SHOWING

Good purchase man!!!

Amazing engines!!! Our 00 Avalon has the same engine. It’s fantastic 😍

مرحبا اود ان اخبرك ان ماتقدمه جميل جدا جدا وكم كنت اتمنى ان اكون بقربك لكي اشاهد ابداعك من قريب واعمل معك ﻻنني ايضا عاشق للسيارات ولكن ﻻاستطيع ﻻنني بعيد جدا فانا من العراق.

Make sure you get wiring harness for knock sensors and may need gaskets for the upper and lower intake manifold. Also change the coolant hose under the upper plenum while you are there. That 1MXFE v6 is great will run 2-3 hundred thousand miles easy

Great buy

I know it's a completely different vehicle, but my '02 Ford Expedition had a switch to turn on and off overdrive. Maybe that's what's going on?

Nice catch

If your knock sensors dont do it believe it or not A bad diod in the altinator will mess with the OD and speed sensors. Just went through it with my Ford v10.

Good video Randy. Hope to see you replace those knock sensors.

i have a different toyota at work and it had a vehicle stability control light on on the dash once the car covered 20 feet,a google told me it was second lambda causing the problem and it was,so moral of the story is replace alternator put good battery on the car and start again,nice car by the way

Very cool win randy congratulations 😊

It doesnt have to be a transmission failure. The altenator can be the REAL problem. It cannot get enough electricity to the components, Thats why the failures. IT CAN BE! Hade alot of car with just those faults.

I rather do two timing belts than one knock sensor on a RX 300. You probably want to change that coolant crossover hose while your at it.

Had the exact same issue with my LS400 took it to toyota to have done, cost about $1200.00 out the door (not including alternator), make sure to use OEM parts, its not a job you want to do twice.

If that's all it takes to get the Lexus going again (and maybe a new battery), then you got a decent deal. $100 or so in parts, a bit of labor to sort it out, and send it down the road for a healthy profit.

Hey Randy, nice Car.... And for a Lexus 180k miles is nothing. Great deal...... Warm regards from Costa Rica.

Beautiful car Randy, dirt cheap! Nice

Nice Lexus! You got a good deal on it!

Bring Mike in on it Randy, team work makes the dream work.... Everybody gets paid.....
