Had he been close to me, I would have taken that tranny for my 62.

The 'Glyde wasn't used in trucks until the '60s. I'd run it with the 235 and Hydro just to be different.

The stock auto was the old cast-iron Hydra-Matic (heavy). This was the unit that B and M Racing Trannies made their reputation on. It didn't have a torque multiplier like the later trannies, but it was pretty stout. If you have a Power-Glide, then someone has already done a transplant. If you want to be different, run that old Hydra-Matic, but don't drop it on your foot! | | | | | Joined: Sep 2006 Posts: 15 Junior Member | | Junior Member Joined: Sep 2006 Posts: 15 | Thanks for clearing things up for me I would like to go back with the Hydro-matic anybody know where I can get the trans and cross member. | | | | | Joined: Aug 2004 Posts: 141 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2004 Posts: 141 | Try going to the B and M Racing Tranny web-site. If you don't see any old Hydra-Matics offered, e-mail their tech department. And, who knows, you might accidentally find one scanning E-Bay.
