Does anyone have a Mopar Performance SRT TCM, p/n P5155177, on an 08 300c SRT?
I bought one in june. It performed no different than a stock TCM. Stock shifts, and the Hold In Gear feature did not work. The car still up-shifted automatically in Autostick.
Has anyone else installed this and had it not work? All I want is the Hold In Gear feature.
This MTCM is advertised to work on 2005-2009 6.1's (as printed on the instruction sheet).
