- Off-Highway Truck:
- 793D (S/N: FDB1-UP)
The problem that is identified in the technical information bulletin that follows does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.
Reports have been received from the field of false warnings of low transmission oil on some 793D Off-Highway Trucks. When you check the sight gauges, the oil level is correct. Do not overfill the transmission in order to eliminate the false warnings. When you overfill the transmission, permanent damage can be done to the transmission and improper transmission operation can occur.
If the false warnings of low transmission oil occurs, install a jumper wire in order to close the circuit. The jumper wire will disable the 172-8660 Liquid Level Switch (Torque Converter) ( Transmission Oil) that is part of the 240-7186 Torque Converter Gp .
