    8L45 Transmission HP Tuners HELP

    So I have a t87a TCM module and have already done the manual "unlock" by sending it to HPtuners and have received it back. What are the procedures to tune the car from here? I also should mention I have already purchased the 4 extra credits it would take to flash the TCM on the car. But now what are the procedure to access the transmission tables for tuning? Thanks in advance!!

    HPTuners will not tell anyone how to tune anything.

    Just read through all the different transmission sub-forums (v8 v6 etc..) for all different types of cars. Your other option is to take a tuning course. Many do on-line interactive tuning courses.

    I was just curious as to what the procedures for actually reading the t87A tcm module and using the credits for tuning were. But I have it all figured out now!
