To avoid solenoid overheating and possible internal damage, do not continuously operate the solenoid for more than 2 minutes at a time.
The TCM will normally cycle some of the transmission solenoids ON and OFF to keep the solenoid passages clean and clear. This is a normal function and may cause the valves to cycle open and closed quickly when the TCM is powered up. This can make the pressure gauge needle flicker or move from high and low as the valves open and close, allowing air to exit the ports where the pressure gauge is not connected.
Use of eye goggles is necessary to prevent personal injury.
To avoid transmission fluid contact with exposed skin, use shop towels to cover the test plate parts in order to prevent fluid from being released into the air, as any remaining transmission fluid in the control solenoid valve assembly will be forced out, and bodily injury may occur.
It is necessary to drain the control solenoid valve assembly of all remaining transmission fluid before attaching the test plate. Use caution when attaching air to the test plate, as any residual transmission fluid in the control solenoid valve assembly will be forced out. Use shop towels to cover the test plate ports in order to prevent fluid from being released into the air.
Preliminary Procedures
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
- Remove the transmission fluid pan and filter. Refer to Automatic Transmission Fluid, Fluid Pan and/or Filter Replacement .
- Remove the transmission electrical connector. Refer to Automatic Transmission Electrical Connector Passage Sleeve Replacement .
- Remove the control solenoid valve assembly from the transmission. Refer to Control Valve Lower Body and Upper Body Replacement .
- Ensure that the manual shift shaft position switch is disconnected and removed before performing the test. Failure to disconnect the switch will cause inaccurate test results and possible misdiagnosis.
