my tranny is good when im moving. if i give it hell i can only get it up to like 200 degrees. but when im in traffic i can get it up to like 230 degrees. my tranny sensor is in the pressure line before the heat exchanger. and it is not slipping. will a cooler with a fan on it help

 

I have the same issue, I have been thinking of going to an electric fan

 

I beleive this is common. I've seen a minivan go way higher than that sitting still. The deal is the tranny has to slip everything to sit still so makes heat. A cooler fan certainly will not hurt, although those things pull alot of juice. Make sure you have enough extra power available for it.

 

if your gonna be sitting in traffic, shift into neutral to keep the gears free and the fluid cycling

 

Good advice, that's what I do if I'm sitting at a long red light or in heavy traffic.

 

does anyone know if the plate style coolers work better then the tube style coolers

 

i've heard some negitive feedback on the aftermmarket trans coolers. something about the fulid trying to return back through the lines or what not, but dont quote me on that

give dave goerend a call = 563-778-2719

 

If you're talking about the stacked plate design then yes, it's more efficient than the older tube design. Don't know about the drainback issues. I wouldn't see a problem with running one though.

 

Well, here's good timing for ya! I just installed a complete kit from bd-power.com Auxilary trany cooler. It lowers the trany temp about 75-100 degrees! It's complete, electric fan and all. I have a temp. sensor on it that turns it on once the fluid coming into the aux cooler is 180 degrees it'll turn the fan on, or wire it to the ignition and it'll run the whole time the truck is on. Great investment especially if any of you are running expensive fluid in there. Not that expensive either, check it out!
