I'm just curious if any of you guys have had a issue like this or know someone who has? On the stock tune my truck shifts and drives perfectly. When I install a tune it pulls very well and I'm happy with that. What I don't like is that when I drive and the TC is locked the second I lift my foot off the throttle the TC unlocks. It will lock up again if I get into it. I could be going 70, 80 or whatever speed and it still unlocks when I lift my foot. Really annoying when I'm towing. I tried Tow/Haul and it works intermittently at best. Even using Manual Mode I get the same results.
The truck is a 2008 LMM. All stock other than a CTS for gauges and a DPF delete tune with some more HP for towing and all around fun.
If any of you guys could shed some light on this I'd really appreciate it:thumb:
Thanks,
Nick
