I'm thinking of installing a Tranny Cooler in my '95 SSE. What type or brand would work? Which would not work? What about size? I've seen some in JCWhitney for about $40. Any thoughts? Thanks.

I don't think so. Usually it'* in front of the radiator. I don't have one. Where would it be?

It'* an SSE, i thought some SSE'* had it, and SSEi had it stock.

Either way, part of the rad is the tranny cooler, is there any specific reason you think you need one?

I still argue that a trans cooler is a good idea for a modded car. One of my main suspicions is the fact that some Series 1 cars (SSE/SSEi) got them from the factory (external cooler) and these transmissions seem to outlast the much 'younger' 4T65 series.

Many members here, myself included, have had 'impending' doom indicated in our transmissions, and after installing 180° thermostats and tranny coolers, had things settle down.

Additional cooling in the summer months can't hurt your car, but it can extend the lifetime of the fritction-dependent parts and fluid. Overcooling in the winter MIGHT be a problem, but I have yet to read/see any proof of that. If you fear overcooling in the winter, a simple manual bypass valve or thermostat controlled cooler may be your best choice.

my transmission was falling out of OD when it got hot outside, and after I put in a tranny cooler it seems to have solved the problem. I might still add some aux cooling to get heat out of the engine bay. I would recommend it if you have a high milage transmission.

I think part of the 4t-65e failure rate is due to the massive amounts of Torque converter adjustment at lower RPMs compared to the 60. Think of it like playing with a clutch on a controlled car. I may get one, depending on how my tranny is after the build.... No L27 in a Bonnie has seen that kinda power...

The 4t65'* have a factory defect where a part of the transmission doesnt get enough fluid due to a crappy valve or something. We had to get a new trans to get the problem fixed. This problem is documented by GM, they even make a kit to fix it I think.
