JANIS TRANSMISSION

HIGH PERFORMANCE 200-4R BUILDS

The TH200-4R case has a dual-bolt pattern that fits Chevy, as well as all Buick, Olds, & Pontiac V-8 blocks.  The external dimensions are similar to the Turbo 350 so it is often swapped in older vehicles to provide an overdrive gear and is well suited for high horsepower applications where an electronically shifted transmission is not in your budget.  200-4R offers a 4-speed ratio ratio of (2.74, 1.57, 1:1, 0.67 / 2.07R).  The 200-4R is the strongest hydraulically shifted transmission to come out of General Motors.   We offer builds from bone stock to high performance builds capable of 1000+HP.
