6L80 TCC desired slip at 4.5 with everything 0

[clinter36]

Been watching my desired slip change between 4.5 and 0. All lock up perameters are set to 0 slip. DOD slip dissabled and all dod charts 0. AC on slip at 0.

At first I thought it was the A/C even though its zero'd out. Now I am wondering if its related to trans temp.

Any ideas?

I would check [TCM] 5660 - TCC Adapt Pressure Min and set this to zero. Normally it has a negative number which allows the adapts to go down if the TCM thinks it can get away with less pressure. By setting it to zero and keeping the corresponding Adapt Max to a positive number, you are only allowing the TCM to add additional TCC pressure if needed, and never take it away pressure.

I have this exact same issue with my 2015 Silverado it only commands 4.5rpm of slip when the AC is on, did you find a fix for this?
