GM 6T70 and Ford 6F50 overhaul

This video covers the overhaul of the GM 6T70 transaxle used in many Chevrolet, Buick, and GMC FWD/AWD vehicles. It's also very similar to the Ford 6F50, which is found in many FWD/AWD Ford and Lincoln vehicles. It's a close cousin to the GM 6T40/45 and Ford 6F35, which shares the same design concept and mechanical powerflow. These transmissions are still offered in 2020 models and arrived on the scene in about 2007. In this video, I cover disassembly, inspection, and reassembly of the transaxle along with measurements and some description along the way. You'll find in this video, I also vacuum check the valve body to see if there are any worn bores. Also, I install at TransGo shift kit to address the common valve body issues found in this Gen I transmission.

This video is intended to teach a student or a technician that's new to automatic transmissions the overhaul and operation of this transmission.

Thank you Transtar www.transtar1.com for providing me with a kit, and thank you TransGo www.transgo.com for providing me with valve body reconditioning kits for the 6T70 first and second generation and the 6T40 kits. Look for another video where I talk with an engineer at TransGo to discuss the kits used in the GM FWD 6-speeds.
