PLEASE NOTE: GM has a transmission that has the same outside dimensions as a 6L90 but uses one less clutch in all the clutch housings compared to a true 6L90. We call this transmission a 6L90LCC (less clutch capacity). Please refer to "Stock Clutch Capacity Chart" and "Length of Main Case Chart" on the "Transmission Specs" tab below to determine if you have a 6L90 or 6L90LCC. When ordering this part, please indicate in the Notes textbox above that you have a 6L90LCC. If you are unable to determine if you have a 6L90 or 6L90LCC, we will determine which transmission you have from the VIN.
