Computer?
Bill I am having a weird issue with my transmission. It won't shift into OD. The light stays on that shows it to be off. Now if I hook up the Snap On scan tool and run through test it will go off during the test. Its not the wiring in the shifter handle cause that has been changed. No codes and the tranny shifts fine 1-3, full of fluid and its not burnt. Trans temps run under 140 pretty much all the time. Do you have an idea what could cause this in the computer? If you think it would be better if I called and talked to you about it next week I can do that. Its a TDE1 computer code.

My first thought was the switch wiring, but you said that's covered. Keep in mind it could go bad again, but since it seems to work with the scan tool, I doubt that the issue. Could be a program problem or maybe even a bad TFT sensor. Any time there is an issue with anything trans related, OD should be locked out. Of course, the OD light should be blinking as well.
Is this something that just happened all of a sudden, or did it happen a couple of odd times and finally get stuck this way? PM me your number and I can give you a call either tomorrow or Monday. Either that, or call me when you have time. Take care.

I was just messing around with it today and unhooked the harness from the transmission and the light stayed on. Seemed kinda odd to me.

I took it off and got lucky with the stock wires and got them correct the first time. That didnt solve the problem though. If you could get me the diagrams I would appreciate it.

Well I guess it had to relearn everything. My first test drive was to pick my boy up from it was just 6 blocks. When I went to go town a van for a friend the light went out but still wasnt just right and after 15 miles it was working just like it was supposed to do.
 Thanks for the advice Bill, I thaught the bypass took it completely out but nope.
