Fluid Line/Hose: Testing and Inspection
When internal wear or damage has occurred in the transmission, metal particles, clutch plate material or band material may have been carried into the
torque converter and radiator. These contaminants are a major cause of recurring transmission troubles and must be removed from the system before
the transmission is put back into service.
Whenever a transmission has been disassembled to replace worn or damaged parts, the radiator must be cleaned by using a mechanically-agitated
cleaner, such as Rotunda Torque Converter/Oil Cooler Cleaner 307-FO11 (014-00028) or equivalent.
Inspect cooler tubes and fittings for damage and leaks. Tighten fittings to specification. If leak persists, replace fittings and tubes as necessary.
When one or more of the transmission fluid cooler tubes must be replaced, each replacement tube must be fabricated from the same size steel tubing as
the original tube.
Using the old tube as a guide, bend the new tube as required. Add the necessary fittings and install the tube.
After the fittings have been tightened to specification, add MERCON V Automatic Transmission Fluid XT-5-QM or equivalent meeting MERCON V
specification as necessary and check for fluid leaks.
Whenever a transmission has been disassembled to replace worn or damaged parts or when contamination is suspected, the following procedure
should be used:
1. Conduct backflushing with Rotunda Torque Converter/ Oil Cooler Cleaner 307-F011 (014-00028) or equivalent. Test your equipment to make
sure that a vigorous fluid flow is present before proceeding. Replace the system filter if flow is weak or contaminated.
2. To aid in attaching the cleaner to the transmission steel cooler tubes, connect two additional rubber hoses to the transmission end of the steel
transmission cooler tubes as follows:
^
Connect the cleaner tank pressure tube to the steel transmission cooler return tube (longest tube).
^
Connect a tank return hose to the steel transmission cooler pressure tube (shorter tube). Place the outlet end of this hose in the solvent tank
reservoir.
3. Turn on solvent pump and allow the solvent to circulate a minimum of five minutes (cycling switch on and off will help dislodge contaminants in
cooler system).
4. Switch off the solvent pump and disconnect the solvent pressure hose from the transmission cooler return tube.
5. Use compressed air to blow out the cooler(s) and tubes (blow air into the transmission cooler return tube) until all solvent is removed.
6. Remove the rubber return hose from the remaining steel cooler tube.
