I have seen 2 basic types of external tranny coolers.
One looks like a small radiator and mounts in front of the stock coolant rad. and relies on air flow to cool.
The other has it's own electric fan and can be mounted anywhere.
My concern with the first type is I have several large offroad lights in front of my grill. I need as much air flow as I can get to my rad. Will I be reducing airflow to rad. if I bolt a tranny cooler in front of it.

My concern with the 2nd type is if the electric fan fails and the cooler is mounted so natural airflow does not hit it I may not know until tranny temps start to climb.

How reliable is the Troyer fan mounted tranny cooler vs. a Tru cool or the one Dirtydog's friend sells without a mounted fan.

I will be ordering this week so any help would be great.

 

i'd just put the tranny cooler in front of the radiator and forget about it...but try to mount it without using the radiator with those nylon straps...make a bracket for it and mount it where its "windy" and you'll be good to go..as far as the tranny temp goes...you could allways install a trans temp guage to keep 'an eye on it ...zap!

 

I just installed a $40 cooler from Napa and also a B&M inline cooler gage last weekend. The cooler went in fairly easy. I installed it inline with the factory cooler, spliced into the 5/16" steel line. The cooler didn't come with any useful fittings so I had to go through the brakeline fitting display and scab together the correct ones to go from the steel line to rubber hose used for the cooler. I wasn't very impressed with the B&M gage. It was the only one I could find that installed inline. The connection to the sending unit kept grounding itself out so I had to add some extra washers to make it work right. Instructions were useless. It still jumps around quite a bit while driving. I have only drove my truck 4-5 times, so I will see how it works after my fix. Haven't towed my trailer yet either. Hope some of my jibber jabber helps you out.

Good point about the fan failure, but the high quality of the fan used in this unit ( provided it doesn't get whacked by something like a stray rock ;-)), should make that a manageable risk, far outweighed by an 'active' cooler's benefits ( better temp control).

Mount it where TP recommends and you should be fine.
