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:
