Again, some of these cold engagement and cold slipping issues with the automatic transmission may be helped a properly working engine and transmission thermostat. At least the transmission fluid would come up to temperature much quicker if the engine warmed up at the proper rate.

I know the newest Torque Pro app supports automatic trans temp display in some cars, it works in my daughters VW with the 6 speed Tiptronic, however, i am not sure the PID for the trans temp in the BMW has been flagged in Torque yet??

Just some more things to ponder??
Torque Pro won't read AT temperatures yet. I have the latest version.
