Transmission code help.

95 is right but you are better off trying a tranny shop first.

Ill keep looking then. Ive talked to a few of them but most are giving me answers that I have already diagnosed. Pretty hard to find one around here from what I have seen so far. How hard is it on the vehicle/tranny with it unlocking and locking all the time?

Any legitimate transmission shop has the diagnostic box that can be plugged into your truck between your OBD2 and the trans that can test the trans operation and the ECM at the same time. It is not a scanner it is a testing device they use of a variety of reasons. I have watched it being used. It takes over the operation of the trans from the ECM for testing purposes.

Either you have a bad solenoid on the TC lockup or some other “high performance” modifications that are not getting along with your OBD2.

I would stop throwing parts at it until you get a proper test done.

Good luck………………
