Replacing the classics is difficult. GM’s 700r4 transmission replaced the TH350 with support for additional speed and a maximum of 650 horsepower. In production until 1992 when the 4L60-E replaced it, many classic cars can use this upgraded transmission from Gearstar.

Which GM vehicles use the 700r4 transmission?

The classic 700r4 high-performance race transmission for 2WD saw use in many cars and trucks. At the time, the offering was General Motor’s best offering.

Makes and models you can upgrade to include:

• The iconic 1983-1992 Pontiac Firebird
• The 1984 Buick Lesabre
• The 1983-1992 Chevy Camaro
• The 1982-1992 Chevy Corvette

This transmission offered consistent power on and off the track. Some of the most well-known models in the GM family used this component.

Which levels is the 700r4 transmission available in?

The 700r4 comes in five different levels. Each targets a specific type of car or truck.

The entry level and off-road level two to the tough and durable level 4 allow you to relive one of the more interesting eras of American muscle. Get your firebird ready for the track or rebuild a Camaro as a classic drag racer. Revitalize your old Corvette and light up the track.
