Speed Gems Transmission Adapters started as businesses often do, to fill a void or a need in a market place. We evolved from a full service transmission shop. We grew to specialize in antique and obsolete transmissions. We started building engine to transmission adapters for two reasons. One is that it is getting extremely expensive to rebuild the original transmissions. Not only are some of the parts getting scarce, but the knowledge level of the people available to rebuild these units competently is diminishing. Transmissions had more internal changes back in the 50s than they do today. To most people, four speed Hydramatics appear to be the same from the outside, but many of the internal parts (mostly hydraulic control) were not interchangeable from year to year, or from model to model. Hot Rodding started as a very creative hobby. Working with what one could afford at the time, cars were built with a lot of imagination. The trend to drop a small block Chevy engine into Hot Rods today shows that the hobby/sport has totally changed. It is now common to see the same type of build out at local car shows. Where can we go from here? Thats what we are interested in. We like to see what no one else has ever done before. Here at Speed Gems Transmission Adapters, we adapt the old motors to modern transmissions so you can use an engine with some personality, plus get a lot better gas mileage with an overdrive gear, whether it is a manual or automatic application. We plan to lead a revolution against the trend of planting small block Chevy motors into everything that moves.
