I have had an accident with the car earlier this year and recently had repairs made to the driver's side and the exhaust system (it sustained underbody damage as well). But every since the accident, I have noticed that the transmission shifts harder than normal, and I had mentioned that to the specialist before repairs were made, but it hadn't been addressed. And just recently, the oil cap had been removed, and it is showing signs on the seal that moisture is entering the engine. My question is, have I possibly damaged a vacuum hose on the transmission and therefore not only causing it to shift harder, but also allowing moisture in as well? If son I need to know what details to tell my local mechanic, so he can have a better idea of what I need, and be able to give me the price so I can get it in. For I do not want it to stay the way the way it is, and allow wintertime moisture and salt into the engine, and destroy it.

Thanks,

Michael Cartwright

It's moisture in engine it's probably a head gasket so have pro pressure check coolant system. If trans shifts harder can be anything so have scanning done for codes as well check for trans alignment problem like broken mount. Hard shifting may be due to an internal trans problem which a trans guy should check.
