wheels lock when downshifting to 1st
hey guys need a little help on this one. Not to long ago i had to get my tranny module replaced. The dealer installed and programmed it. A month or two down the road i was towing my boat and put the tow haul mode on and i noticed when i would come to a stop it would jam into first and pretty much lock the damn wheels up. It would only do this in tow mode. Checked with the dealer and they couldn't find any codes and they beleived it to be a clutch in the tranny. Tow haul mode wont even engage or come up on my dash now. any suggestions?

How does the transmission perform not in tow haul? If it works flawlessly in normal operation then I would have to suspect a faulty program on the TC for tow/haul.

It works with no problems at all when not in tow haul mode. I took it back to the dealer initially to see if they messed up with programming the tranny module and everything checked out normal which i find a little disturbing since this never happened before they replaced the module. any more ideas?

Yeah, I'd say check the connections, try another dealer. It sounds like something is wrong with the programming. That's very odd. Sorry I can't really offer any better advice.
