350 Lock-Up
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.
The lockup feature will typically lower cruise rpm
by 200-500 rpm 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
Lock-Up feature is available on all of our TH-350
models for an additional $249.00

4L80E
Shown with
COMPUSHIFT
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.
#PT4L80EHD
