The existing torque converter low oil level sensor can be damaged by debris on certain 793F, 793F CMD, 793F XQ, and 793F HAA Off-Highway Trucks. If the existing sensor is damaged it can cause unplanned downtime to repair or overfilling of the torque converter sump due to incorrect low oil level events. |

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 18% 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.
|
Refer to Special Instruction REHS9319 for installation instructions. It is advised to perform this update during a regularly scheduled PM for transmission oil change-out, every 1000 service hours or 6 months, when the fluid is already drained out of the torque converter sump. The image below shows a model of the new guard on a typical 793F torque converter. |
