What tranny do I have? - 11/30/2007 7:47:21 PM    bobslsc   Posts: 11 Joined: 11/14/2007 Status: offline Need help in determining what transmission I have. It is a '93 GMC Jimmy with 4.3 Vortec engine. The trans is starting to slip after 153,000 miles. I think I'll just look for a replacement tranny to swap, but what trans should I be lookin' for?

"E" is for electronic shift and you should have a wiring harness with a bunch of wires to the transmission. _____________________________ Give a man a fish and he will eat for a day, teach a man to fish, and he will sit on a boat drinking beer for a life time (in reply to otnietdehoooo) Post #: 3

Prior to that it was the 700R4, then 4L60, and then the 4L60E. To verify crawl under the truck and look at the passengers side of the tranny. If you see a wiring harness, its a 4L60E, if you see a black cable, its a 700R4/4L60. _____________________________ "Some people spend an entire lifetime wondering if they made a difference.

I took teh clutch packs out of my '00 4L60E tranny and put them in my '87 700R4, and the '87 700R4 was a 60 degree tranny. That means it wont bolt up to a 4.3 or a V8. GM used the 700R4 from the early '80s to the ealry '90s. Then it switched to the 4L60 until '93. In '93 GM went with the 4L60E. Off by a year, not really. They are all basically the same thing. The only difference is the valve body and how its controlled. _____________________________ "Some people spend an entire lifetime wondering if they made a difference.

There are a bunch of little tricks rebuilders do to inprove teh performance and reliability of the tranny. A used tranny will cost you half a rebuilt one. Check the Self-Help Section. I did a write up on how to drop the tranny, that will save some cost. Installation is reverse of removeal.  _____________________________ "Some people spend an entire lifetime wondering if they made a difference.
