Our most popular performance transmission, we have been modifying and improving this trans since it was first introduced in the early 80’s. We offer several versions of this trans for applications up to 575 horsepower. This trans has a low first gear ratio of 3.06 to 1 and an overdrive ratio of .70 to 1 which translates into stump pulling low end and a 30% reduction in cruise rpm.
This trans was built with a Chevy only bolt pattern, but we have a package for Buick, Olds, Pontiac, and Cadillac people so you can enjoy the benefits of this excellent transmission too.
We also provide a custom rebuild service for those interested in keeping the original trans but need an upgraded version to handle additional power mods. Call for more details.

The 350 Lockup transmission uses unique hydraulic circuitry to apply a clutch in the torque converter to completely eliminate slippage. What this does for the enthusiast is allows higher stall speeds to be used for acceleration without causing slippage and excessive heat build up when cruising just like the overdrive GM transmissions use. The lockup feature will typically lower cruise rpm by 200-500 rpm or even more depending on speed, stall speed and rear end ratio. This translates into improved fuel economy and lower operating temperature of both the transmission and engine. This is a great alternative to an overdrive transmission when space is a concern and is considerably less expensive as well.

The 4L80E was introduced by GM in 1991 to replace the rugged, but aging 3 speed TH-400. The 4L80E was the first fully computer managed transmission in the GM fleet and has proven to be a strong and reliable transmission in 3/4, 1 ton, and Motor Home Chassis, providing overdrive towing capability and precision electronic shift performance. Naturally Hot-rodders were drawn to this trans as a means to finally get a reliable overdrive to go behind high output big blocks and tow rigs. Unfortunately, it took the after market a few years to come up with a simple and easy to install stand alone computer system that could be fitted to older, non computer controlled vehicles. Well the wait is over and now anyone wishing to harness the full power of their engine up to 1,000 horsepower, can do so with one of our 4L80E transmission and computer packages.
Each trans and converter are built to order to insure the correct stall speed and performance modification per application. The trans is then dyno tested and the computer calibrated for shift scheduling and firmness as well as converter clutch application. The end user has only to install the trans, make 4 or 5 simple connections, and go have fun! If you’re making to much power for a 700R4, and need an overdrive, this is the best choice you can make for performance and drivability for your car or truck.
