Authentic Custom Transmissions
The staff of Complex Auto Authentic Custom Drivetrains, a division of Complex Auto Engines and Transmissions, understands the pride and satisfaction that our customers have in the ownership of a classic vehicle.
We show that understanding in our attention to detail, the quality of our work and in making sure that you will be satisfied with the experience you have with us – from the interaction with our staff to your completed transmission. We offer custom “days gone by” remanufactured transmissions for your special project. The transmissions we can build for you include: Borger Warner Three Band, C4s, Dual Range, Dynaflow, Ford-O-Matics, Hydramatics, Jetaways, Jensens, Roto Hydramatics, Powerglides – cast and aluminum, PowerFlights, and more.
The Authentic transmissions we build can be found in Buicks, Cadillacs, Chevys, Chryslers, DeSotos, Dodges, Fords, Hudsons, Kaisers, Lincolns, Mercurys, Nashes, Oldsmobiles, Plymouths, Pontiacs, Ramblers and Studebakers.
We focus on maintaining authenticity because many of the transmissions we receive are for numbers-matching vehicles. Should a major casting such as the case, bell housing or extension housing not be suitable, we will contact you for your instructions. If you should instruct us to replace any of these castings, we will return your original castings so that you can document the authenticity of your vehicle. You can request that your Complex Auto reman transmission be painted or left unpainted as the original unit might have been.
