One thing I'm concerend about is the size of the tubes. If the tubes are too small, it might exert a pressure change of some sort. Resulting in less AT fluid circulating.

Also, I would assume that you have to add more than the usual 4 qts (1 gallon) of AT fluid when the cooler is in right?? How much??

I have the second one the perma cool. just get the 16000-18GVW version and you might have to add maybe a 1/4 of a quart bottle of fluid not much at all really, I also noticed a little better shifting with it installed our TCM regulated shifting by alot of factors and fluid temp is one of them.

Cool bro....thanks!!!! Did you hook it up in series with our stock ones, or take it out completely and use the permacool instead?? Again, thanks!!

I have it hooked up after the stocker, much better that way, if you want to get rid of the stocker then make sure the cooler you get is rated 3x GWV

Thanks man. One last thing, I just ordered the permacool kit, does it come with 'EVERYTHING' ready to install or do I have to get some type of fittings at a local car store?? Again thanks man.

I have a hayden 18000 GVW
They come with "everything" but be prepared to buy a longer hose if you want to take it out of the engine bay, most cooler only comes with a very short hose, that is almost ridiculous

Speaking of tranny temps.......if anyone wants an Automatic Transmission Temperature Gauge....I have one for sale -- $30, never used.
