700-R4 RV/SS

General Motors Four Speed automatic transmission with 30% overdrive. These transmissions are a great alternative to a manual transmission for installation in street and performance applications requiring an overdrive. Ratios are: 3.06 first gear, 1.62 second gear, 1.00 third gear and .70 fourth. It allows lower first gear starting line acceleration and a 30% overdrive for the highway. Stall speeds range from 1800-4000 RPM. It is especially good for high performance street rods and machines that are driven on a regular basis. This transmission is built to a specification that has proven itself time and time again.

• 1987 and later cores are used due to GM updates
• 5 pinion low planet for 4X4 Transmissions
