In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 19% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
|
If the transmission has failed due to failed Clutch #2 splines, replace Clutches #2, 3 and 4 with new 173-3272 Friction Discs as referenced in previous Service Magazine SEPD2042 (published August 26, 2015).
Refer to the 797F Planetary Disassembly and Assemble Procedure (KENR8372). |
