bbe Posted January 14, 2010 Share Posted January 14, 2010 I have an 88 automatic 4l 4wd that is not getting power to the transmission computer. The set up does not match the wiring diagrams from chrysler or mitchell. I need the amc wiring diagram. It is in the best transmission shop in town and he has about given up. I went online ready to buy a factory manual found your site and I sure hope some one can help. Quote Link to comment Share on other sites More sharing options...

bbe Posted January 14, 2010 Author Share Posted January 14, 2010 Thanks for all the information, I sure could of used it when the crank shaft sensor went out. My mechanic needs an amc wiring diagram for the tranismission computer with wire colors etc. There is no power on the computer. bbe Quote Link to comment Share on other sites More sharing options...
mythreesons Posted January 15, 2010 Share Posted January 15, 2010 The wiring diag. is probably in the zip file for the 88FSM on Greatlakes. (I'm not sure as I have the files all seperated out on a flash drive.) Your mechanic did check the fuse for the tranny computer, didn't he? It should be on the harness very near the tranny computer.

bbe Posted April 9, 2010 Author Share Posted April 9, 2010 Back on the road again. I found a TCU on E-pay, bid $100 was the only bidder and got it for $10.36 delivered. Plugged it in and off and running. bbe Quote Link to comment Share on other sites More sharing options...
kastein Posted April 9, 2010 Share Posted April 9, 2010 Next time you need electronics let me know, I hit the junkyard quite often and can usually find stuff for cheap. There is an 88 in the JY I go to right now, the TCU would have cost ten bucks. I don't charge extra, you pay what I pay plus shipping. The only catch is that I get busy at work randomly and it may take me a while to find what you need. Quote Link to comment Share on other sites More sharing options...
