Torque Converter Contamination Inspection

Torque Converter Contamination Inspection






NOTICE: Do not use water-based cleaners or mineral spirits to clean or flush the torque converter or transmission damage will occur. Use only clean transmission fluid designated for the transmission and converter being serviced.

1. If a new or remanufactured torque converter is not being installed, the following steps must be completed.
2. With the torque converter on a bench, pour a small amount of transmission fluid from the torque converter onto an absorbent white tissue or through a paper filter and examine the transmission fluid.
3. Observe the color and odor of the transmission fluid. The fluid should be red, not brown or black. Odor may indicate an overheating condition such a clutch disc failure.
4. Examine the stain on the tissue for evidence of particles (spec of any kind). Examine the transmission fluid level indicator for signs of antifreeze (gum or varnish). If particles are present in the transmission fluid or there is evidence of engine coolant or water, a new torque converter must be installed.
5. If there are no particles or contamination present, drain the remainder of the transmission fluid from the torque converter.
6. Add 1.9L (2 qt) of clean transmission fluid into the converter and agitate by hand.
7. Thoroughly drain the transmission fluid.
