Automatic Transmission/Transaxle – Vehicles With: 307-01-4 307-01-4 6-Speed Automatic Transaxle - 6R80 DESCRIPTION AND OPERATION Transmission Description œ Overview 6R80 Transmission E128660 This transmission has an internal thermal bypass valve contained within the case. This transmission uses planetary gears with hydraulic electronic controls. The Transmission Control Module (TCM) and the main control valve body units form a composite element that is installed as a single unit inside the automatic transmission. This transmission has the following features: ‡ Six forward speeds ‡ Torque converter with an integral converter clutch ‡ Electronic shift and pressure controls ‡ Single planetary gear set ‡ Double planetary gear set ‡ Two fixed multi-disc clutches ‡ Three multi-plate clutches All hydraulic functions are directed by electronic solenoids to control the following: ‡ Engagement feel ‡ Shift feel ‡ Shift scheduling ‡ Modulated Torque Converter Clutch (TCC) applications This transmission has a mechatronic unit which contains: ‡ Transmission Control Module (TCM) ‡ Turbine Shaft Speed (TSS) sensor ‡ Output Shaft Speed (OSS) sensor ‡ An internal P, R, N, D selector shaft position sensor ‡ Transmission Fluid Temperature (TFT) sensor Engine power reaches the transmission by a torque converter with an integral clutch. The 6 forward gears and one reverse gear are obtained from 2 planetary gearsets.
