Trans Cooler

[truckyard1]

I'm looking for a good but low priced trans cooler to replace the crappy little thing that's in there stock. I know summit has some pretty cheap, any particularly good size/brand? I wanna go cheap-ish, whenever my e40d goes i'm putting in a zf5, so no reason to dump money into it.
EDIT: Where the heck is the temp gauge sender?! I replaced the actual engine sender, but I can't find the gauge sender for the life of me! Am I a major DA, or is it that difficult to find?

I've seen people go two routes.

1) they buy an additional cooler to run in line with the other one.
2) they buy a cooler with a fan attached so they're assured decent air flow.

I was thinking about the fan route, but thats a bit more money then I wanna spend on this

Coolant temperature sensor or Engine Oil temperature? EOT is down by the High Pressure Oil Pump. Coolant sensor and switch are both on the front of the engine. One has wiring that comes out of the same loom as the Cam Position sensor and the other is on the pump I think (I can't remember which is the switch (for overtemp idiot light) and the other is for the gauge. Cheers!

I'm putting that on my truck. Should cool about the same as the smaller tru-cool that guys run in the bumper. If i ever run into heat problems i'll ditch it for a bigger one or mount a fan on it, but this one should be fine.

I have a bypassed rad setup and have a derale 13700 cooler with a 10" 650cfm fan. I want to ensure slow speed low airflow situations aren't going to cause me to overheat. I had it all mounted up but my first cooler was factory defective. Jegs was good about shipping me a replacement fast and reimbursed shipping. I'm mounting mine behind the bumper where the air gaps are. I'll take some pictures Sunday when I get A chance to install it.

I had a smaller cooler before that worked ok but of
I was romping around a lot or crawling in 4x4 I would see temps creeping on 200* which I didn't like.

My setup is 155 @ jegs and comes free with the fan thermostat. I don't see why you wouldn't keep your cooling solution with the zf5? My thermostat will kick my fan on at 180 now and hopefully ensure I never see dangerous temps. It's a 16 pass tube and fin cooler. Really nice looking unit designed to be remote mounted.

Edit** this is the cooler, but the free thermostat promotion has ended. http://www.jegs.com/i/Derale/259/13700/10002/-1

Not a bad looking cooler.

And you can't use it on a ZF5 cause they don't have a pump, so there's no way to move fluid through a cooler.

Interesting. That I did not know. You could hook it up as an in line aux oil cooler though!

I looked into putting a cooler on my ZF 5-speed years ago after putting in a new tranny(they do get hot, I had a temp gauge on mine ... up to about 250F pulling a load on a nice grade). It is not a cheap endeavor! You will need modified (or billet) PTO covers, a pump (Weldon, Tilton, Mocal ... not cheap), good Stacked Plate cooler, temperature switch for pump, all the lines and fittings (also not cheap for decent stuff). I sold the truck after we got the 97. I run the Tru Cool Max (4739) behind the bumper on the 97 (also plumbed into the radiator cooler) with a Dieselsite external transmission filter setup. Cheers!
