I have '08 G2X. (korean version. same with sturn sky redline or gxp)
sorry for my poor english.
custom intake, performance autowerks EFR6258 turbokit, trifecta tune.
some months ago, i noticed the light by the gear selector "D" was not on.
but my car ran well.
2 months ago, all the lights by the gear selector went off!
and whatever gears I select(D, 3, 2, I or L), my car shifted as like "D".
And during engine is on, I can't open the trunk. I think it's because i can't sense the P position.
there are more problems.
one of that is hard up-shifting and very hard down-shifting. furthermore, maximum boost drop down to 1bar(=14psi). As I think, it may be transmission protection mode.
and when I turn on the ignition, service ESC, service TCS, ESC off are on display and check engine light is on.
these are DTCs.
[] P0700 - Transmission Control System Malfunction
[] P1915 - Internal Mode Switch Does Not Indicate Park/Neutral (P/N) During Start
[] P1820 - Internal Mode Switch Circuit A Low
I tried to change the gear box, camshaft position actuator solenoid valve with my friend's. and reflash the ECM,,but none of them works.
there are only about 200 g2x in korea. so GM dealers don't know well about my car.
please help me,,
