I've got a odd problem. The wife was driving home, turned onto our street and lost all power to the wheels she was able to coast home. She tried shifting to low ,2nd, reverse and the engine just revved. I tried to start it the next day and the starter engages the flywheel, but just turns the flywheel. The engine doesn't turn over. I removed the starter and was able to turn the plate by hand.? It appears to have a aftermarket transmission. We had issues 2 years ago also. The Flexplate/ flywheel was replaced because it was cracked. It was bending and making a racket.
