'78 trans-am trans

Home  \  Classic Cars  \  '78 trans-am trans

a friend of mine is getting his car road worthy again and after driving the car there were a couple of things that need attention. it is a 1978 trans-am with a 400 pontaic engine and a 4 speed manual trans. i have a couple of questions concerning the transmission.
1. how do i tell the difference between a borg warner t-10 and a saginaw?
2. how much is a rebuild kit?
the reason im asking is his syncros are going bad and need replacement before he can drive the car.

also, it has a rochester quadra-junk carb on it and the secondaries are not opening. do i rebuild the carb or tell him hes screwed and tell him to buy a holley or edelbrock? TIA :thumbs:

Take a look at this link, it has the info you seek. This is also a great place to get the kit from. I've been very happy with their service and parts in the past.


As for the carbonator, like them or not you really can't beat a Quadra-Jet on the street. Small primaries give you decent mileage around town and big secondaries allow good power when your foot feels heavy. This is especially true if the engine is otherwise stock because lets face it, it's a low compression smog engine. The only down side is that a reman Rochester costs almost as much as a new Holley/Edelbrock. The up side is that you can bebuild it for under $50, new float and all.
