i have a 2002 4t65e that is acting a bit strange.
when you take off from a stop sign it revs up in first then switches to second. As soon as it switches to second if you apply a little more gas, the tranny sounds like it shifts up to third and the rpms drop then within a second goes back down into second again. If i stop and start again but hold the gas pedal constant during the shift the tranny acts normal. Does anyone think i may have a bad TPS thats throwing the transmission off?
