Indeed, the 87-91 Bonneville-era RWD Toyota trannies I know about call for Dexron II. Contrary to what jr'* talking about, Dexron III may (unconfirmed) be linked to gearbox failure, speculation says that the Dexron III may actually be too grippy, burning out the clutches prematurely. While Dexron II (or rebadged equivalent) was used from the factory, Toyota since came out with a fluid known as Toyota Type T-IV, Dexron IV? Apparently it'* good stuff for the Aisin A340E transmissions.

Could this stuff be Dexron IV (I think it exists, does it not?) put out by Toyota?






just adding to the discussion, this should make it interesting

Hmm, V6 Camrys of those years did like to eat trannys, but the general life you'd get out of them would probably be a bit more than '87-91 Bonneville.


I only know about the RWD trannies of that era, a few newer and current Lexus models use essentially the same tranny, but maybe with a 5th gear and other assorted refinements...

Yea i noticed that my fluid looked awfully brown, though still smelled good, after just a little while. Today i pust a quart of Lucas in 'er and drove it soft about 5 miles to get it pumped through, then her her have it, and it grabbed way more solid. I told u i swear by this lucas stuff. I BEG you to try it. No more fun for a while though just got dumped with 8 inches of snow. Lakeville knows what i mean.
