So the tranny isnt working to well right now I presume

with the circuit interuption I would think that may have triggered the other codes

Sounds like you have a power distribution issue or possibly a bad ground

i put a convertor in it and it wont lock up since.i took my computer out and swapped a friends in just to see if that was the prob.but it isn't.the only difference in trucks is his is 2wd.thought maybe the loch up solenoid was bad but i pulled it and it aint.

i did this also.


When mine didn't lock with the switch Dave had me check under the truck to see if the computer was sending a signal to the converter to lock. To do this he explained to jack the rear wheels off the ground and have someone put the truck in drive. The two transmission lines that run to the front of the truck, feel them and have the person in the truck run the truck up to lock up speed. If you feel a spike in the lines at lock up then the transmission is getting the signal to lock up. If you do this be very careful and take all the precautions to keep the truck from falling off the jack stands. It sounded a little sketchy to me but I did it and felt the spike. This meant my converter was shot and I had to get a new one. Hope this helps.

Check this out dude

Lock Up Complaint: Issue 52, page 39, offered an in-depth look at torque converter lock-up. Although the author was specifically talking about the '98.5 and newer trucks, this tip applies to torque converter lock-up on Turbo Diesels '94 and later.As documented, many people have replaced the TPS or APPS, transmission temperature sensor and numerous other parts trying to correct the ongoing converter clutch problem with varying degrees of success.
Well, for all of the shadetree mechanics in Turbo Diesel land, before replacing any parts or wasting time connecting a scan tool or voltmeter to the electrical circuit, start with the easiest step first.
I have found the cause of the lock-unlock problem to be a frequency-induced electrical noise into the ground circuit of the battery which causes a fluctuating voltage signal from the TPS to the PCM.
The Solution: Locate the 10-gauge ground wire that runs from the negative post of the passenger battery to the back of the alternator. This wire is often tan with a black stripe.
Starting at the back of the alternator loom where the tan/black striped wire heads for the battery, wrap the wire with a piece of tin foil about 4" - 6" in length. Wrap the tin foil with black electrical tape to secure it in place.
Road test the vehicle. If the problem is corrected, smile.

could this all of the sudden happened when i did the convertor swap?it worked fine before and never after?and what i was wondering it could i go down to the plug on the trtanny and splice into the pin that grounds the tc solenoid and hook it up to my lock up switch and bypass everything,at least for a test,would that work?
