Info - 5L40-E/5L50-E Automatic Transmission Service Parts and Labor Operation Codes for Transmission Internal Service and Overhaul

This bulletin is being revised to include the 2007 model year as well as the Pontiac Solstice and Saturn Sky and revise the application chart. Please discard Corporate Bulletin Number 05-07-30-010A (Section 07 -- Transmission/Transaxle).

Important: Always check the transmission ID before performing internal repairs.

*3GBG unit can be serviced with 4GBG unit assembly and/or components

The above chart does not include STS-V and XLR-V models with 6L80 Automatic Transmission

Full service for 5L40-E and 5L50-E automatic transmissions is available in the above vehicles.

Service parts and labor operation codes are currently released for repairs, including the bell housing, pump assembly and all major internal components.

The transmission case (24) and parking pawl actuator (613) are not serviced separately at this time. If case replacement is necessary for any reason, the complete transmission assembly must be replaced.

Callouts 3, 6, 7, 8 (incl 9), 10, 11, 12, 15 (incl 14), 16, 17, 18, 19, 20, 21, 52, 600, 601, 607-612, and an overhaul gasket/seal kit are available through GMSPO.

The difference from standard full service approach is that each major sub-assembly is only serviced as a sub-assembly to minimize the need for selective spacers and washers required to properly rebuild these sub-assemblies.

Only three selective parts (5,14,22) are required to overhaul either a 5L40-E or 5L50-E instead of thirteen, which would be required for a complete overhaul servicing all sub-assemblies separately.

The Unit Repair Manual describes how to disassemble and reassemble each sub-assembly for inspection and cleaning purposes, but only complete sub-assemblies will be available as service parts.

Additional labor codes have been established and are also shown in the illustration.
