Chenova Posted January 31, 2008 Share Posted January 31, 2008 I have heard that a powerglide transmission is versital in that it can be connected to either a six or eight cylinder engine. Is that true?I have a 1962 Nova with an aluminum case powerglide connected to a 194 6cyl. The transmission has started slipping and I was wondering if it would be cost wise to rebuilt this one or replace it with one that is a low mileage rebuild?

mrpushbutton Posted January 31, 2008 Share Posted January 31, 2008 Depends on how much the low milage rebuild is, how handy you are (are you paying R&R labor or are you doing it yourself?) and who/where/how good the rebuilder would be for the original Powerglide. Have you considered having it looked at, on the car by an experienced (= old time) trans man? I could just need band adjustment.I have a '63 Chevy II, pictures of it were on the "why are all the crappy 60s cars colletctible", I think that thread dissapeared as passions were running high--I didn't help matters!

Guest Dave Wyatt Posted January 31, 2008 Share Posted January 31, 2008 That is true of the"modern" aluminum case 'glides, but IIRC, the old cast iron units had 6 cyl and 8 cyl bolt patterns and could not be interchanged.The aluminum case transmissions have two different first gear ratios, a 1.76 for V8's and 1.82 for 6 cyl. (hope I don't have that bassackwards) Link to comment Share on other sites More sharing options...
Chenova Posted January 31, 2008 Author Share Posted January 31, 2008 Thanks for the input. Your 100 looks good. Link to comment Share on other sites More sharing options...
Chenova Posted January 31, 2008 Author Share Posted January 31, 2008 Thanks Dave. Whether you have the numbers backward or not, you still answered one of my questions. The 6cyl tranny won't work with 8cyl. Link to comment Share on other sites More sharing options...
1931Pontiac Posted February 1, 2008 Share Posted February 1, 2008 The 182 and 176 will work behind a 6 and a 8. The difference is the first gear ratio which affects the RPM drop between low and high. That was a trick to put the 182 behind a 8 to get a quicker launch. They are pretty simple and not that difficult to rebuild. Just watch the difference in the linkage on the transmissions if it comes out of a different Chevy model. I would check the band adjustment if it is just slipping.

Rusty_OToole Posted February 2, 2008 Share Posted February 2, 2008 Chev redesigned their inline 6 in 1963. It used a lot of V8 parts and would fit the same tranny bell housing as the V8.Previous to that the 6 and 8 had different transmission interface and therefore different housings even though the internals were largely the same.The new type 6 debuted in the Chevy II in 1961 and was adopted across the board in 63.
