Fluid Condition Check

1. Perform the fluid level check.
2. Observe the color and odor of the fluid. It should be dark reddish, not brown or black. Odor can sometimes indicate that there is an overheating condition clutch disc failure or band failure.
3. Use an absorbent white facial tissue to wipe the fluid level indicator. Examine the stain for evidence of solids (specks of any kind) and for signs of antifreeze (gum or varnish on the fluid level indicator).

If specks are present in the fluid or there is evidence of antifreeze, the transmission fluid pan must be removed for further inspection. If fluid contamination or transmission failure is confirmed by further evidence of coolant or excessive solids in the transmission fluid pan, the transmission must be disassembled and completely cleaned and serviced. This includes cleaning the torque converter and transmission cooling system. Do not perform any further checks before cleaning and servicing the transmission. During disassembly and assembly, all overhaul checks and adjustments of clearances and end play must be made. After the transmission has been serviced, all diagnostic tests and adjustments listed in the Diagnosis by Symptom chart must be completed to ensure the concern has been corrected.
