SUBJECT:
Inspection Procedure for A/T Fluid Cooler
Hose Connections
INTRODUCTION
This bulletin will provide an inspection procedure for the A/T fluid cooler hoses and piping connection points between the radiator and the transmission assembly.
SERVICE PROCEDURE / INFORMATION
^ If oil seepage or residue is found at any of these connection points, first determine if it is transmission fluid (ATF) or possibly a different fluid from another source. In some cases, it could be residual seepage left over from a prior repair or original vehicle assembly.
^ If necessary, clean any residue using brake cleaner or parts washing solvent then thoroughly dry the area with a clean cloth.
^ Start the engine and allow it to idle for 5 minutes. Next, hold the engine at 1500 rpm for another 5 minutes. Re-inspect the connections for any recurrence of ATF seepage. If seepage is found, replace the hose(s) as needed and clamps. IMPORTANT: Do not reuse the hose clamps. When replacing clamps, never substitute a different style or type of clamp other than the original application. Incorrect specification clamps may not be fully effective at preventing leaks.
^ In the event a hose needs replacement, once disconnected, carefully inspect the sealing area of the companion metal pipe for any damage or scoring as shown in the shaded area of the illustration.
^ If seepage is not found after the first test and inspection, run the engine again at 3000 rpm for 5 minutes then inspect the connections again. If OK, the procedure is complete. If seepage is found, replace the hose(s) and/or piping as necessary along with the clamps. Repeat the test procedures after any hose and/or pipe replacement to verify the repair is complete. REMINDER: Do not reuse the hose clamps.
