Procedure for using a tank heated transmission fluid cooler line flusher
CAUTION: Whenever the transmission has been serviced or a remanufactured transmission has been installed, the transmission fluid cooler
tubes and the remote filter manifold (if equipped) must be cleaned and backflushed to remove any contaminants or transmission failure will
occur.
NOTE: Install a new oil-to-air (OTA) cooler as part of a transmission overhaul, or when installing a remanufactured transmission.
NOTE: Early build transmissions are equipped with a remote transmission fluid filter which is located on the driver side rear of the transmission.
When carrying out an overhaul or installing a remanufactured transmission a new filter element must be installed.
NOTE: Repeat repairs will occur if the transmission fluid flow does not meet specification. To avoid repeat repairs, carry out the fluid cooler flow
test. See: Testing and Inspection/Component Tests and General Diagnostics/Torqshift Automatic Transmission/Transmission Fluid Cooler Flow Test
NOTE: Plug the flusher into a 110-volt outlet and allow it to heat up to the correct temperature.
NOTE: Carry out this procedure with the oil-to-air (OTA) cooler and the transmission removed from the vehicle.
NOTE: Leave the remote filter lines connected.
1. If equipped, remove the in-line transmission fluid filter. Install a straight pipe with hose clamps in its place.
2. Remove the remote filter and magnet (early build vehicles).
3. Clean and reinstall the remote filter housing (early build vehicles).
4. Flush the transmission cooler return line first.
1
The transmission cooler return line can be identified as the line that runs from the OTA outlet (driver side) to the rear of the transmission.
2
Using the appropriate fittings and quick disconnects supplied with the flusher, connect the flusher pressure and return lines to either end of the
transmission cooler return line.
3
Switch the flusher pump on and allow it to run for 60 seconds.
4
Turn the switch off after 60 seconds and disconnect the pressure line.
5
Blow air through the cooler line until the fluid is drained pack into the flusher.
6
Disconnect the flusher return line.
5. Flush the transmission cooler pressure line and radiator in-tank cooler as follows:
1
The pressure line and radiator in-tank cooler must be back flushed, then forward flushed. This is necessary to thoroughly flush the in-tank
cooler
2
The transmission cooler pressure line can be identified as the line that runs from the OTA cooler inlet to the front of the transmission.
3
Using the appropriate fittings and quick disconnects supplied with the flusher, connect the flusher pressure line to the radiator in-tank cooler
outlet. Connect the flusher return line to the transmission cooler pressure line (the cooler line near the transmission bellhousing).
4
Switch the flusher on and allow it to run for 15 minutes.
