For the 1984 model year, passenger cars equipped with a C-3, C-5, or AOD model transmission and an auxiliary cooler will have an auxiliary bypass fitting or "H" fitting. The "H" fitting allows transmission fluid to bypass the auxiliary cooler to avoid excessive cooling of the transmission fluid when ambient conditions drop to
- 20 ~F or lower.
Cleaning Procedure - Cooler Line and Cooler for Vehicles Equipped with an Auxiliary Cooler and "H" Bypass Fitting
Visually check the cooler lines in the area of the auxiliary cooler in-line. If an "H" bypass fitting is present, follow the procedure outlined below flushing the cooler lines and coolers.
REMEMBER:
The flushing of the cooler lines and coolers is mandatory after any transmission service that generates contamination. This must be done to avoid repeat services.
1. Set up the torque converter and cooler cleaner (Rotunda Model No. 014-00028 or equivalent) according to the instructions supplied with the equipment.
2. Flush the cooler lines and cooler according to the equipment instructions. This should involve connecting an inlet hose from the cleaner to the transmission cooler-out line (at the transmission) and connecting the cleaner return hose to the transmission cooler-in line. Place the end of the return hose in the reservoir of the cleaner. Do not reconnect the cooler lines at the transmission.

3. Disconnect the auxiliary cooler-in line and the auxliary cooler-out line on the side of the "H" fitting closest to the auxiliary cooler. (Refer to the typical passenger car, truck, and Econoline illustrations, (Figures 15 through 18). This is the field fix installation; production installation may vary.)
4. Set up the cleaner by attaching the cleaning hoses to the auxiliary cooler hoses. Some applications may require inserting a section of cooler line tube in the auxiliary cooler hose in order to attach the cleaning hoses.
5. Flush the auxiliary cooler.
6. Blow air through all the lines to remove residual cleaning fluid.
7. Reconnect all fittings.
8. Check for leaks.
