2G Automatic transmission question - 99 GST

[richieboy89]

i have a mhi small 16g installed on my car. its an automatic and it seems when i let the turbo spool my transmission is missing shifts b/c my car lurches. i can notice it more now since i have brand new tires and no longer get the vibrations from bad wear. i tried explaining this this best i could sorry.

I don't understand the symptoms.
If you are holding WOT the transmission should shift at about 7000 RPM, the car should lurch on each shift. On my Talon it lurches at 40MPH, 70MPH, and cough, cough.

The car should not lurch between shifts. If it's missing a shift at WOT it still shold not lurch, just studder on the rev limit.

Please describe the symptom in terms of gear, RPM, and throttle position.
