My 67 Chevelle

“Very nice job of changing my trans. over to a 700r4. These guys went the extra bit to make sure the transmission not only was installed properly, but made it part of my Chevelle overall. My car acts like it always had a 700r4. They totally met my expectations, and their work is clean.” — Rick See more reviews here.

When the 700R4 automatic overdrive transmission came out in the early eighties, many hotrod enthusiasts started converting their three speed transmissions over to automatic overdrive transmissions (A.O.D.). They liked the fact that they could run low gears yet still keep their RPMs down, at highway speeds.

There were great concerns that the A.O.D. would not hold up behind high performance engines. We knew that a stock 700R4 would need to be modified to handle the horsepower and shift properly with the wide range of hot rods that they would be put in. Most of these cars would be running a variety of different engines, differentials and tire sizes. And the cars would vary considerably in weight.

We researched many ways to make the 700R4 stronger and more versatile. It is very important that we build the transmission to the car in which it will go in. We have many different ways to set up this transmission and are putting them behind everything from “stock” 350 engines to 500 horsepower high performance engines and four wheel drives. We have been building these transmissions now for many years, and have many happy customers with a wide range of vehicles.
