Hello my friends, how are you? My name is Abu Hamza. I joined the forum. Of course, I am a beginner. I have a question regarding the programming of the GMC Yukon gearbox. I want to modify the transmission so that the gear shift is from 1 to 6, the pressure of the RPM does not go up to 6000, I want to shorten the speed of the RPM Or when switching a tiger, where can I get the gear settings in the file? Thank you
