Thread: Manual shifting

zzp sets their torque converter lockup real high. I have to go over 49 mph for the torque conveter to lockup in performance shift. It's a little lower in normal shift but not much. If you don't go over that mph the your torque converter won't lockup.

On the PCM they sent me, they completely removed TCC lockup in 3rd gear. Most streets around here are 35MPH, so I had to go to 45MPH for lockup. Killed my MPG.
