Lexus GX460 (1 Viewer)

No. I’m just stating that not all failures are the same. Some could be just failed valve body parts but I’ve seen other reports where other components damaged the valve body as well. Not a AT expert by any means just observations of other failure reports.

i was researching a 460 serviced by lexus for the past 10 years. If you go the lexus website and enter the vin, you can see the history from the lexus dealer in detail. None the less the customer brought the vehicle in for a 4lo and cel and now traded it in and the dealer recommended a new trans to them.. Thank god i researched the vin through the lexus website//maintainence history///read this thread because i would of got $%@# for a transmission.

Sorry brothers, if your trans is running good, low miles, I would do a drain and fill every 10k.

Yeah, you can do a trans flush every 10 k miles, if you have the time and money to do it then great. To me it'd be kind of like using synthetic oil and still changing your oil based on petro oil calendar, when syn oil last's almost twice as long.
For me, I truly believe it's over kill. Every 90 k should be fine unless you're abusing it with heavy tows, hard shifts, etc.
I know this will probably open up a can-o-worms.
Toyota/Lexus isn't like some American auto manufacturers that build a planned obsolescence in their products (do Pinto's and Vega's come to mind??)
Toyota/Lexus engineers design and build for the long haul, so I have a tendency to believe and follow their factory service specs.

But as mentioned, that's me.

Circling back around with an update on my 2014 GX460 with 85K miles.
I was still able to purchase an extended warranty, so I did. Thankfully I did as 2 weeks later it wouldn't shift past 3rd even if you let it warm up before driving it.
I had it towed 115 miles north to the closest dealership and the warranty paid $6400 for a new transmission + transmission coolers, all before I made the first payment on the vehicle. The service advisor at the dealership was a blessing and fought for the correct fix from the beginning. Dealership was also able to locate and get a Lexus rebuilt transmission within a week. Its been a month now since I brought her home and I've had no issues at all!

@adidas6804 mentioned a drain and fill as opposed to a tranny flush. Whether every 10k is overkill is another debate, but I'm planning to do a drain and fill every year or every 15-20k as preventative maintenance, especially after seeing the care care nut episode on this.

 

[Brian060901]

Yep, looks like I have joined the club. 165k on my 2011 GX 460. Never had a problem till last winter. When cold out side transmission
Just doesn't shift correctly until ? 5 min, 1/2 block or until I cycle thru all the gears once. Then all is perfect.
Trans fluid as far as I can tell has never been changed.

Once warmed up or if hot out side transmission shifts perfectly. Looks like changing the fluid at this point makes things worse. Wondering what percentage of trannies fail if fluid changed late in the game, like mine?

Does anyone know were Lexus have their trannies overhauled, a mechanic told me. Is it one location? My local Lexus dealer says they do them in house, (I doubt that), One of the mechanics mentioned a shop called "last chance" They claim to do some for the dealership?

Wonder how long I have, no codes.

Any suggestions?

Thanks Brian

i d strongly suggest you do one drain and fill (correct not flush) every 10k, to help keep fresh fluid in circulation. its easy to do and really not a big deal. seems alot are having transmission issues. Transmission fluid is cheap, new tranmissions arent.

 

[Rednexus]

I'm usually the odd man out but I recommend a pain drop, filter change, and full fluid exchange. All of this can be done via the transmission cooler in front of the radiator (if yours does not have a cooler I'm not sure how to do it). That way you get 100% new fluid and all of the gunk out of the pan. Drain and fills are probably fine for keeping the fluid fresh on a lower-mileage rig. On a higher mileage rig you just contaminate the new fluid with the old fluid.

I totally agree, BUT, it seems like doing the first drain and fill (If not previously done, at high milage) seems to trash a good number of transmissions.

I am trying to get a good idea of how many people do their first drain and fill at 165K and SURVIVE. I have certainly heard of a good number of GX's that the first high milage drain and fill is followed by failure with in 1k miles.

Again my trans is smooth as silk, AFTER 5 min warm up, or going thru the gears prior to moving. Yep, I am on borrowed time.

Thanks Brian

P.S. I had already decided to do a pan drop and filter change. I have every thing needed in a box in the garage. But, now trying to get a line on a new tranny prior to proceeding

If your transmission is cooked after a fluid change, it is very close to being cooked anyway. That usually only happens on very worn transmissions where the clutch packs have lost most of their material to the fluid (so the suspended particles provide friction between the clutches). If your transmission is that far gone it will not have much more life regardless of if the fluid is changed or not. Repeated drain and fills will accomplish the same thing (slowly removing the suspended clutch particles), just more slowly than replacing all of it at once.

FYI I changed my 5-speed at 135K with Valvoline Max Life and have had zero issues. The fluid was dark but not cooked. It's also hard to know how the P.O. treated the transmission as, in my experience, it's not that hard to overheat a transmission in a GX due to the under-sized cooler and lack of torque converter lockup in lower gears.

 

[r2m]

If you looking for a back up tranny in case yours doesn't survive the flush, may I suggest a used one and get it rebuilt? You may get it much cheaper over all after the rebuild. I'm not sure, just spit-wadding here.

 

[Pick]

Maybe supply chains have corrected some but I was finding that used transmissions were (significantly) more expensive than new because they were available. When I did mine last year, I was finding used between $5.5-$8k. New ones were on significant waiting lists so it drove used demand way up.

Hey Acrad,
I have been milking the final breaths out of the transmission in my 2010 gx for the last two years. It has finally come to a point where the end is near and a full replacement is eminent. It was a good run, made it to 174k. Curious, have you or anyone else posted a parts list to execute a transmission replacement [pro tips as well]. Saw a number of threads related to various aspects of replacing the trans but not an actual parts list. I apologize if I over looked the information in the forum. The basics I know below:
*Transmission assembly [for me a reman]
*Gasket kit
*Trans filter
*Fluid
*Rear main seal
*New trans cooler [upgraded]
*New coolant lines or good flush

Thx
My gx below

The above just assumed that the torque converter came with the reman transmission from Lexus or OEM parts dealer. If that isn't the case (which is a question).... I guess add torque converter to list??

Thank you for posting this. For anyone looking into a new transmission (rebuild), I recommend doing so before you're dead in the water as Jasper has about a month wait (3yr or 100k warrenty) and Lexus has an almost immediate turnaround time for about 3k more (1yr or 10k dog s*** warrenty). There are probably other rebuild options, but I did not find them and I did not want to entertain the used transmission option.

As always, thanks to all for inputs and advice.

 

[Acrad]

@GXFLEarl - It will come with a TC. As for parts lists... best info on that would be others who had it done to post list. If anyone needs me to track down any specific PNs let me know.

If possible...post your work orders

 

[maingear]

I just got the lightshow and techstream shows P0761 & P2714. It runs great. With a lift in my own shop, I'd rather disassemble and rebuild what I have rather than gamble on a 3rd party overhaul. On the other hand I do have over 220,000 Miles. Dropping pan to see how much metal it has made.

Need to get hands on an overhaul manual and see what special tools are needed.

 

[Acrad]

I‘m not sure how accurate this is but Car Care Nut on Youtube stated that the reman Toyota/Lexus transmissions have all new internals. The only part re-used is the case.
