The Engine vibrates in gear and also out of gear. Out of gear its not too bad, but I can still feel it. While in gear, it gets worse at certain speeds and not so bad at others. I drove it from New Jersey to Ontario (8 hour drive) and it really tired me out
It is a 4.3 litre engine with a 4L60 E automatic transmission. The engine is not missing. Tommorrow I will remove the cap and check for that side play. Thanks so much. BTW...I'm a true GM guy and have always used Delco parts
