SYMPTOM/CONDITION:
Transmission high shift effort may be experienced in cold weather operation at ambient temperatures below 32~F (O~C). Shift effort improves as
transmission reaches normal operating temperature.
On 2WD vehicles equipped with the KM130 (R5M21) series transmission the lubricant viscosity may be the contributing factor.
On 4WD vehicles equipped with the V5MT1 series transmission the lubricant viscosity, synchronizer rings and springs may be the contributing factor.
DIAGNOSIS:
If, after a cold soak, the transmission shift effort is found to be excessive during the initial start up, and the effort improves as the transmission reaches
operating temperature, inspect the transmission in the area of the fill plug. If there is no white dab of paint just above the fill plug, perform the following
repair procedure.
A dab of white paint above the fill plug indicates the following procedure has been completed. Refer to the appropriate service manual for additional
diagnosis.
