TRANSMISSION OIL COOLERS
Q. The trans cooler in the radiator is leaking and is expensive to repair. Can I use a Hayden transmission cooler to eliminate it?
A. Yes. Always choose one of the larger Hayden coolers when eliminating the radiator cooler to compensate for the loss of cooling from the radiator. In most installations we recommend use of the radiator tank cooler to provide maximum cooling and to comply with most manufacturers warranties.
Q. Should the cooler be installed before or after the radiator?
A. Hayden recommends installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission. Installing the cooler before the radiator will still provide additional cooling and may be necessary in some difficult access applications.
Q. Can you over cool the transmission fluid?
A. Transmissions are not highly sensitive to cool operating temperatures. However, in sub-zero (20-30° F) weather conditions transmission fluid can actually gel up in an external cooler and cease to flow, causing damage. Use of the radiator cooler actually helps warm the fluid under these conditions. It is critical in extreme cold conditions to use the original equipment cooler in series with the auxiliary cooler and allow the vehicle to warm up before driving.
Q. What is the difference between an Ultra-Cool® and Rapid Cool® trans coolers?
A. Ultra Cool® is a tube and fin (serpentine) design that is a time proven cost effective design. The round tube design is the strongest and most reliable cooler design but only gets cooling air on the forward facing side.
The Rapid Cool® design is a plate and fin design similar to most radiator designs. The flat plates allow more contact with the cooling air. This provides a design that is about 1/3 more efficient size for size than comparable Ultra Cool® models.

At this point I'm not running a stall converter. I have been looking at the Hayden plate design. Seems to be a good compramise for size and price.
