new tcm installed on my 2007 pontiac solstice do i have to reset it?

Question

after installing it i tried resetting it by disconnecting the battery but it now shifts hard,rpms run high and the speedometer stops working intermittedly and the fuel range gauge shows a blank. The coolant temp reads ok as well as the engine temp. do i have to take it somewhere to have the new TCM linked properly to my vehicle, can i reset it myself? replacing the TCM fixed my problem of suddenly jerking when slowing down but now it just feel like its running in the right gear.

Answer 1

You will have to reprogram the TCM (transmission control module) , this ensure that the transmission relearns all its adaptive pressure, and values, More than likely the Dealer has the reprogram capabilitys
