Week to Wicked Product Feature: Performance Automatic 4L70E

Add Article To List

Speedway Motors and Classic Trucks teamed up to build a 1952 Chevy truck in celebration of Speedway Motors’ 65th anniversary.

To transfer the power of the LS3 they slipped under the hood, they reached out to Performance Automatic for a 4L70E automatic transmission capable of handling the load. Performance Automatic filled that request quite nicely.

Ryan Manson and Damon Lee take some time to talk about the 4L70E and what it comes with. Right out of the box the transmission delivers, coming equipped with the StreetSmart SimpleShift system. The 4L70E is an electronically controlled transmission, and the SimpleShift system gives you a great level of control, allowing you to set and tune shift points, among other variables.

Performance Automatic can tailor the torque converter to your project as well. The converter included with this 4L70E features a stall speed of 3200-3400RPM, which should mesh nicely with that GM Performance LS3 in front of it.

PA inspects each core shell to ensure that the foundation is solid. Most of the time the finished product is shipped raw, as you would expect any transmission to be. This one however was powdercoated to our specifications.

The transmission is also dyno-tested prior to shipping, so you know when it shows up you can bolt it in and keep on trucking without worry.
