A very knowledgeable guy in our local Chevy club who has a lot of automatic tranny experience doesn't like the old cast iron PowerGlides much and recommends going to a more modern aluminum version. My question is, can this be used with a 235 and a torque tube closed drive shaft? Anybody got any experience or advice about this approach? This is going to go into my '50 Tin Woodie, for which I have a '54 PowerGlide and a'53 PowerGlide rear end (3.55:1).
Whaddaya think folks? Thanks for any suggestions and opinions.

 The Aluminum powerslide, (pun intended),to my knowledge, didn't come out until the middle of 1962,,, AND it had the same bolt pattern as the V-8's. So you would need some type of adapter to hang it on the back of a 235 I6. Of course converter and starter issues come to mind. Next problem is motor mounts. I'm sure one could fabricate some type of servicable mounts. BUT,, hooking this to a closed torque tube is beyond my expertice.. I'm sure enought money, adapters and work could make a fit...
Now the question, why??? If you want a better trans You can go to an open drive line and use a multitude of later Chevy trans' that would be better and stronger than the powerglide..

The aluminum Glide first came out in 62 in full size 327 equipped passenger cars; if your 62 had a six (235) or 283, it had a CI Glide. Chevy II/Nova also came with aluminum Glides in 62, as did trucks. All went to the aluminum Glide in 63. No way to connect the aluminum Glide to a torquetube, so it's open driveline conversion time. You're really stuck with a CI Glide if you want an automatic with the 216/235/261, and keep the torquetube. Butch/56sedandelivery.

Not possible, sorry. The rear housings of the 49-54 powerglides and the aluminum ones are not the same, and to my knowledge, not interchangeable. You would HAVE to swap out to an open driveline as mentioned before...

As mentioned above, there was never an alum PG setup for the pre-62 6cyl engines. Thus, no way to mate an alum PG to a torque tube.

The only set up I ever saw that mated a later model tranny (TH 350 in this case) to a torque tube was a disaster waiting to happen. The engine/tranny was pushed too far forward, requiring the radiator to be moved forward as well. The weight distribution was too far forward. Thing handled like a whale wallowing in a turn. With that much work ahead of you I'd strongly suggest either staying with the old tranny or converting to a open drive. There are several ways to keep a original looking engine while gaining a late model tranny and rearend.
