Because transmission fluid cools, lubricates and transmits hydraulic power, it is critical to maintain adequate fluid levels in your system at all times. When the fluid level is too low, the converter, bushings, bearings and clutches do not receive an adequate supply of fluid. If fluid levels are too high, they can aerate and cause your transmission to shift erratically or overheat.
For maximum performance and protection, transmission fluid and filters should be changed according to engine manufacturer recommendations. Harsh environments, severe operation or extreme duty cycles may require more frequent change intervals. Periodic inspections of drive shaft components, electrical charging system, transmission oil coolers and engine cooling systems should also be performed to identify potential problems and protect against transmission malfunction.
