Re: Help identify transmission in 89 TA
its most likely a 700r4. You can supposedly tell what transmission you have by the pan. I think theres a post on here somewhere with an image, unless its on another site I go to.

no no, the pans are different shapes/different numbers of bolts for different transmissions.
