Transmission Cooling
Inspection and Verification - Automatic Transmission
NOTICE: Install a new Oil-To-Air (OTA) transmission fluid cooler as part of a transmission overhaul or exchange. Failure to follow these
directions may result in transmission damage.
NOTE: When internal wear or damage occurs in the transmission, metal particles and clutch plate material can travel into the torque converter, the fluid
cooler tubes, the radiator in-tank transmission fluid cooler and the Oil-To-Air (OTA) transmission fluid cooler. These contaminants are a major cause of
recurring transmission concerns. To prevent future concerns, remove these contaminants from the cooling system before placing the transmission back
into use.
1. Clean the contaminants from the transmission fluid cooling system. Carry out the following:
-
Transmission fluid cooler backflushing and cleaning See: Component Tests and General Diagnostics/TorqShift/Transmission Fluid Cooler
Backflushing and Cleaning
-
Torque converter flushing
-
Torque converter cleaning and inspection
Also carry out the transmission fluid cooler flow test. See: Component Tests and General Diagnostics/TorqShift/Transmission Fluid Cooler
2. Visually inspect for obvious signs of mechanical damage, incorrect component installation and system leaks. Repair as necessary.
-
Install a new or remanufactured radiator when fluid is found leaking from the in-tank transmission fluid cooler.
-
Install a new OTA transmission fluid cooler if there is leakage from the fluid cooler, and always as part of a transmission overhaul or
exchange.
3. If the fault is not visually evident, GO to Symptom Chart - Automatic Transmission Cooling. See: Symptom Related Diagnostic
