Hey folks, I have a 79 Z28. It has a 350 transmission. Now what Im wondering
is: Is there any difference in a 350 transmission for a Z28 and any other
350 Chevy transmission? Ive had my suspicions about this transmission since
I bought the car 2 years ago and this morning it like to never caught in
reverse. It still kicks pretty good in drive though. Im just contemplating
rebuilding this transmission or going to the junk yard and taking my
chances. What really sucks is I sent it to the body shop this morning to get
it finished and now its money on top of money. Well that's the way it is
with an old car. Spend a lot but at least its a car that brings a lot of
I'm in a similar situation with my '68 327/325 Powerglide, been slipping on
Trying to decide whether to:
A- get rebuilt at AAAMCO, Cottman's or a local
B- get rebuilt outside the area
C- get a new/rebuilt replacement put in
If the tranny is original, are there "matching numbers" that would make
rebuilding this one a better choice?
I'd hate to spend weeks waiting for a rebuild :(
Bruce, there are numbers to match on most. We just rebuilt a 400 for a 71 SS
Chevelle it had all #'s matching. The number is on the tag on the side where
it tells you 400 or 350... Not sure on the powergildes thou..
With your powerglide there are different low gear ratios for the trans.
there are 1.76, 1.82, 1.89, 1.96, 2.03, 2.11 that I know of.
Depending on what you are doing with the car... I wouldn't go to AAAMCO or
cottman for rebuilds, especially on any high performance app's. (but that's
me) There are a lot of good high performance trans builders out there I
would stick with one of them.
There are also a lot of companies out there offering ready to install
trannies for a decent price.
I wish I still had my numbers matching powerglide... we rebuilt ours and put
it on the shelf for completion of our project... a bottle of muratic acid
spilled on it one night, by the time we caught it... there was not much of a
case left... for one of our '69 SS convertable's.
Good Luck ...
