Inliners International Forums General Discussion Truck Talk Powerglide in AD Truck

For the last several years, I've been contemplating replacing the 3 speed in the '51 with a Pglide, but keeping the stock torque tube and rear end. I have (maybe) found a Pglide from a '54 car that is complete with the flywheel and torque converter. My question is will the Pglide match up to my stock torque tube? And what about the rear end ratio? It seems like I've read where the Pglide cars had a 3.55:1 rear end. Will the trans work with my 4.11? It also seems like I read that the torque tube set up was the same between the car and 1/2 ton truck. Is that right? Your help is greatly appreciated. TIA

Hi Tim, My Chevy parts book shows the 41 to 54 pass. using the same internal shaft in the tube and the same carrier housing. It shows the 48 to 54 1/2 ton using a 7/8" longer internal shaft and a different carrier housing than the car. Might be usable if you use the whole assembly but your tires might move forward in the wheel opening by 7/8". The 3:55 will give you better crusing speed but either rear end should work with the trans.
