Lumina V6-191 3.1L VIN T MFI (1993)
Service Action: (Figure 2)
There are many differences between the prior third roller clutch and input sprag assembly and the new dual sprag assembly. Therefore, transaxles built
prior to February 1, 1993 must be serviced differently than transaxles built on or after February 1, 1993.
To accommodate the new dual sprag assembly, it was necessary to modify and/or change the following components:
^
Input sprag assembly (654/665).
^
Retainer input sprag clutch (655/666).
^
Input sun gear spacer (657/667).
