Hummer H3 V8 Transmission Tuning
Been working on setting up part throttle shift tables, torque converter clutch engagement points, line pressures, shift speeds, TCC engagement pressures, torque management....ect All done using HP Tuners. This setup shows light throttle driving (~30% throttle). Shift points have been extended, and torque converter clutch locks in immediately in 3rd and 4th gears. Much less slipping of the Trans with TCC engaged all the time, and is more efficient for fuel mileage/daily driving. Next I will be playing with adding in a 2nd gear TCC lockup table.
