I've got the auto, with DTT TC and VB, Pac Brake and Smart Controller. It's been 15 degrees or colder here for the last month and I only drive my truck once a week in the winter. The last two times I had the truck out, with the e-brake off, I've noticed that the TC doesn't unlock when coasting until I either touch the brake or reach 35 mph. I haven't noticed this before. When the e-brake is on, of course it stays locked until about 30 mph. Am I just experiencing another attack of CRS (can't remember stuff) disease, or is something up with the tranny? In every other way it behaves normally.

Well guys, given enough time, I figured it out for myself. In case anyone has a similar problem, I solved the TC lockup problem described above by recalibrating the APPS.

 

Hey, good news! Glad you got it figured out and also that you shared the fix with us.

Thanks!
