Fluid Condition Check
- Carry out the Fluid Level Check; refer to FLUID LEVEL CHECK .
- Observe the color and odor of the ATF. It should be dark reddish, not brown or black. The odor can sometimes indicate that there is an overheating condition, clutch disc failure or band failure.
- Use an absorbent white facial tissue to wipe the fluid level indicator. Examine the stain for evidence of solids (specks of any kind) and engine coolant gum or varnish on the facial tissue.
If specks are present in the fluid or there is evidence of engine coolant, the transmission fluid pan (7A194) 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 repaired. This includes cleaning the torque converter (7902) and transmission cooling system. Do not carry out any further checks before cleaning and repairing the transmission. During disassembly and assembly, all overhaul checks and adjustments of clearances and end play must be made. After the transmission has been repaired, all diagnostic tests and adjustments listed in Diagnosis by Symptom must be completed to ensure that the concern has been corrected.
