TRANSMISSION MAINTENANCE Transmission Lubricants Manual Transmission Service Intervals Standard Transmission Oil Level For recommended types and brands of all lubricants, see the transmission manufacturer's Service Manual and Preventive Maintenance Schedule on page 5-12. NOTE Manual transmissions are designed so that the internal parts operate in a bath of oil circulated by the motion of gears and shafts. The vehicle must be parked on level ground. Check all hoses for kinks, deterioration, chafing, and leaks. Adjust kinked or chafing hoses to eliminate restrictions and prevent further wear.
To ensure proper inspection, it may be necessary to inspect under and inside frame rails and unclip harnesses, hoses and cable bundles. See the Transmission Operator's Manual for information on checking the transmission oil level. 5 (03/17) Y53-6077-1B1 5-153
