Well first of my friend has a 1983 camaro 2.8l with the 200c. well i not sure how good these tranys are but he thinks it may be slipping. does anyone know how good these trannies are?

They are not very strong.

must be pretty bad to slip behind a 2.8!

I read the 200c were not durable, unlike the 200 4R which holds up in ordinary applications. You will find info on this if you do a search.

the 200c is exceptionally weak. - Tell you're friend to start looking for a t350 in a junkyard.
ordinary? low 10 sec GN's aren't exactly what I'd call ordinary....

The 200 4r is basically the same thing as a 700r4 but has closer ratio gears, it was designed for use in light cars.

Now if its actually true that its pretty much a 700r4 i wouldnt trust it too much in these big boats!

The 200-4R and the 700R4 have nothing in common. They're entirely different designs.

Nope, me neither!
I haven't heard of anyone building a 200c (it fails behind ordinary engines), but a 200-4R is rated to 330 ft.lbs. stock, and reputedly can be built to deal with a supercharged nitrous-injected small-block. It's a nice little tranny with even gear spacing and a high o.d. good for both higway & strip. Being small should make for low h.p. loss, I guess?

My memory sometimes fail me, but doesn't some repair books deal with the 200 and the 700 in the same book, many parts being the same?

C.R.S. - can't remember sh*t
- nope, they're completely different.

That would be me LOL but every time I try to go up a hill it just does nothing have to flore it then when I get to the top were its flat it starts acting funny almost like its sliping but after you drive it a lil ways it stops these trans are weak but there better then nothing I think LOL
