upshift light


Registered User
At what rpm does this light come on? I see it illuminate at initial key on but ive never seen it while driving. I dont rev much higher than 3, 000 to 3, 500 rpm and maybe hit 4, 000 plus once or twice but never hit redline. Is redline the parameter that triggers it? Im not going to test it as I think I have a small combustion leak somewhere and truthfully the car seems to want to be in the next gear much sooner than redline.

AFAIK, it only comes on with auto trans, somewhere north of 110+ mph, but only when not in OD, so it depends...

with a manul it comes on around 5,200 ish. it also comes on and stays on when the crank position sensor is shot.
