Q. My transmission will not stay in overdrive. It has gotten more sensitive over time. Originally it would kick out of overdrive with fast acceleration or by using rocker switch. Is there an adjustment for this?
Q. I have a 79 vette 383 stroker. For some reason I can’t seem to solve a problem with leaking valve cover gaskets. The leak is coming from the left rear of the engine. The gaskets have been replaced several times within a short period of time.
Q. I have a 2007 ZO6 with about 7500 miles on it. On a recent trip, after accelerating to about 6500rpm the engine lost power and ran erratically. The check engine light did not come on. An On Star diagnostic reported a problem in the air intake system. I got the car to a nearby friend’s shop and we’re moved the air intake snorkel and discovered a fair amount of engine oil that had gotten on the air filter as well as the mass airflow sensor. After removing, cleaning, and reassembling the intake system the car ran fine on the way back home. The car is at my dealers now and they can’t figure out what caused the problem or how to prevent its occurring again. There’s no evidence that the oil came from any external source. It had to come from somewhere inside the intake system. Has anyone experienced this problem or have suggestions as to cause, fixes, etc.? Any help would be appreciated.
