Title: Transmission Upgrade . . . 1957 Eldorado
Post by: 27913 on February 21, 2017, 08:16:05 PM
Is there any member out there who has previously installed a 700R4 in place of the original Turbo-Hydramatic in their '57 Cadillac? 

I am in the process of this upgrade in my '57 Seville and wonder if there might already be a modified cross member available . . .

The original transmission is not a Turbo Hydramatic but rather a 4 speed dual range Hydramatic. I had a 700r4 in a 1984 Oldsmobile 98 and was never impressed with it. The original 4 speed is a heavy duty work horse.
