Title: HELP..Tranny Question!!
Post by: DuckAholic1 on September 20, 2013, 07:46:02 pm

My truck is an 87 c10 w/ 5.7 350 engine, & what I thought was a 700r Tranny. Now I am not sure.
These #'s are all I can find on the side of tranny. 89TUM7. If any one can identify it PLEASE let me know. Also feel free to tell me how to go about identifying it. Thanks Alot.  :-\

What's under the hood??? If you have to ask maybe we shouldn't race...
