Hello my name is chris im pretty new with z's so bare with me. I bought my z October last year its a 76 280z, when i drove it home that day the car was fine. About a month later the car was sitting wile i was working on the paper work and getting my license my tranny suddenly gave out it wouldn't go into reverse for a wile but it would go on drive. Then it completely took a sh**t. So maybe about twice a week i would turn on the car let it run for a wile and i notice it started trowing some white smoke nothing big but some and i didn't think much about it i just thought well maybe just its because the car has been siting for a wile. OK so 2 days ago i swap my tranny i went from auto to 5speed n everything went great took me about 5 hours thanx to my uncle. So now to my q's i read up on the reasons for white smoke and theirs a few for example blown head gasket, oil rings, valve seals n so on. But I did read up on some guy having the same problem his transmission was going bad and started trowing white smoke form the exhaust do to i believe pressure causing some fluid going into the combustion chamber is this true? Also at idle it doesn't trow smoke only when i step on the gas. Well i just wanted to get your guys opinion on this and where should i start first on figuring out the reason for the white smoke.
Sorry for writing allot.
