Sealed automatic transmission question

So I am just about to pull the trigger on a 2007 FJ. Almost 100K on it, but very well maintained, and mostly freeway. (For those following my other posts, it des have the rear locker.) The seller is actually my doctor and a car nut. He has 9 cars and takes excellent care of all of them. Also a former champion figure skater and diver, but I digress.

I asked him if he ever changed the automatic transmission fluid. He said it was a sealed system and it was not called for. I had that on a BMW a few years back. Historically, the issue was that the transmission fluid would get acidic and eat up the transmission, hence the need to change it. Have they changed the characteristics of the fluid?

Assuming normal driving, how long should an FJ tranny last, same as the engine?

The FJ handles almost like a sport car. Probably my favorite feature. It definitely is bare bones, though. No covered center console, no pockets in the back of the seats.

Thanks. Great board.

Toyota uses a new low-viscosity synthetic ATF, but the auto transmission is not "sealed", it just doesn't have a traditional dip stick. It does however have drain, fill, and level-check plugs and can be drained or flushed. I flushed mine the first time at about 45,000 miles and I'm over-due for it again. If you don't tow anything or do a lot of heavy-duty four-wheeling it will last a long long time, but I'm pretty anal about preventative maintenance because I tend to keep my vehicles a long time.

Re: Sealed automatic transmission question

at 106k miles, my fluid was a dark brown so I had it changed. I'd suggest changing it out.

Follow the yellow brick.
Multivex mirrors, BudBuilt skid, Bandi mount, Midland CB, Firestick, Baja Rack, SAW full suspension, MB 72 black rims, Duratrac p285's, body mount chop, on engine number 2. But it's gone now... So I just hang around

Re: Sealed automatic transmission question

Lot of threads to search on this--As of my last inquiry, Toyota does not recommend and dealerships will NOT PERFORM A full-flush/replacement

I had a little more then 50k on my '07 and wanted it changed before driving to Alaska
Two different dealerships in the area wouldn't do it. Said there was no need at such low miles. While on the road I also called two different dealerships and was told the same thing.

I would bet if you inquired with someone who knew what they were talking about @ the dealer, it's a drain and refill (basically leaving the majority of the old fluid in the x-mission) NOT a full flush/replacement of all fluid)

Re: Sealed automatic transmission question

A private mechanic should be able to do this easily, just drain out what you can. Some will get stuck in the torq converter. Youll get 80% of it most likely. Fill back up with OEM fluid, good to go! Should be labor of an oil change.
