LMS car with trans issues while still cold

[jimmyducati]

I have a recurring symptom in my '10 SHO with the LMS 4+ 93 tune, the transmission won't shift into 6th for the first 5-10 miles when it is extremely cold out (below zero). I figured it was written into the tune somehow to prevent going into overdrive while the trans is still cold.

This is in factory tuning. Sixth gear is locked out until trans reaches operating temperature.

Ive only felt this once i think with stock. I always notice the car takes longer to shift in cold weather i kind of like it cause then it warms up faster. Its to my understanding you do more damage with the coolant out of operating temperature then the engine going a few hundred revolutions faster.
