Has anyone installed one of these? http://www.zzperformance.com/grand_p...ts1.php?id=547

I would like to know if it could really replace a conventional cooler.

I highly doubt it would replace a cooler of any resonable size, but I would think it would help some with cooling but how much.... We don't know.

Anything that promotes and compliments an auxilliary cooler is beneficial for hydraulic transmission fluid.

The optimum temperature for hydraulic fluid is 120 F. Temps above this value are detrimental to the long term health. Replacing fluid often is one solution.
Most of our trani'* run about the same temp as our engine coolant. This is too high IMO.

The GM designers have many other considerations they have to consider that are no always good for wringing more HP from a drivetrain.

I may seriously consider this mod.

Cruising on the highway my trans sits at about 155 while the coolant is 180. If I start to really get on it for a while, it'll climb closer to 180-90. Either way, it'* still too high if your 120F value is right though.

I seriously doubt that pan would be capable of removing even 5 degrees of heat. A trans cooler is far more effective.

I think it would do a little better than 5 degrees. I mean its basically like a heat sink.
There are pans like this that are advertised to drop temperatures up to 45 degrees. Those designs are a little better though imo.

But, taking in account the cost of the pan, it can't really be worth it. You could get a great viscosity controlled auxiliary cooler for 50 bucks.

The fluid would have to stay in the pan for longer than it does during normal circulation to lose any heat there.

I agree, that'* hardly worth the cost or effort.
