Can front-to-rear play of the flywheel (due to an internal engine problem) ruin the transmission? My car is back in the transmission shop following a rebuild at the beginning of summer. I took it back in because of a noise from a cracked flywheel, and the mechanic told me that it had already "torn up" the transmission he'd rebuilt. (When the transmission went bad the first time, he had discovered that the flywheel was cracked that time as well.) He says the transmission and flywheel will fail again
unless the engine is rebuilt/replaced because the engine is producing this back-and-forth motion. It sounds plausible. It would explain a lot of mysteries. But I have no idea if it's even possible.
