- No Converter
Technical Information:
The differences between 4L60-E, 4L65-E, 4L70-E (4L60 Family Transmissions) are primarily by gearset design. Each planetary gearset in the 4L60 has four pinion gears, and the 4L65 and 4L70 have five pinion gear planetaries. The input torque ratings for the different transmissions are; 4L60-E: 380 ft/lbs, 4L65-E: 430 ft/lbs and 4L70-E: 495 ft/lbs. External fit, form and function are identical between the three variants of 4L60-E, 4L65-E, and 4L70-E transmission assemblies.
Selecting the right transmission greatly enhances the driving enjoyment and performance feel of your vehicle. Chevrolet Performance has you covered with modern, electronically controlled automatic transmissions that offer great strength to match their powerful crate engines. Each electronically controlled automatic transmission is designed to provide smooth, consistent, trouble-free performance on the street and to endure high-power engines on the drag strip. SuperMatic Transmissions offer the ultimate in automatic transmission strength and torque capability, and every Chevrolet Performance transmission is backed by a 12-month warranty.

Chevrolet Performance transmissions also deliver the fuel economy benefits of a modern, electronically controlled overdrive transmission so don't worry about taking your resto-mod for a long drive--it'll be comfortable and economical! More importantly, you buy the transmission outright so there's no need to deal with shipping messy cores. Complement your transmission with a controller kit for plug-and-play operation; conversion kits are also available to allow the use of electronically controlled transmissions with older Chevy engine applications.
