Harsh Shift on Coastdown
Checks
DEFINITION: Harsh shift on coastdown
Fluid level low and/or contaminated,
or unit filled with the wrong type of
automatic transmission fluid (ATF)
Calibration
Automatic Transmission Input
Speed Sensor Assembly (73)
Automatic Transmission Fluid
Temperature Sensor (36) - part of
the Automatic Transmission Wiring
Harness Assembly (33)
External Automatic Transmission Control Valve Body Assembly (39)
Remove the automatic transmission control valve body assembly (39) and
inspect the items listed. Inspect the internal bores and the valves for signs of
wear and/or damage, including internal contamination. If unable to verify any
repairable concerns, replace the complete automatic transmission control valve
body assembly (39).
Inspect the ATF level and color. Perform "Transmission Fluid Check" and make
sure that the fluid does not smell burnt, and shows no sign of coolant cross-
contamination. If unable to determine if the transmission has the correct type of
fluid, drain the unit and refill with the correct ATF and retest.
Using a scan tool, verify that the current calibration level downloaded into the
transmission control module (TCM) is correct for this platform, including that the
correct TCM is being used for the platform. Refer to the appropriate service
information to verify that both engine and transmission calibrations are the most
current up-to-date level.
Inspect the automatic transmission input speed sensor assembly (73) for loose
electrical connection and/or signs of physical damage that could cause erratic
output. The magnetic end of the sensor should be free of any metal shavings/
particles, including heavy friction material build-up. If metal or heavy friction
material is found, diagnose the cause and repair as necessary.
Using a scan tool, verify that the transmission fluid temperature is correct. If the
transmission fluid temperature is NOT correct, diagnose and correct as
necessary.
