transmission cooler

do all f150s have transmission coolers cause today i looked under my f150 and i saw a little radiator type thing with lines runnig to it from near the transmission, and its in front of the engine radiator so i guess tht is a transmission cooler. i never new it had one but its good cause i tow a camper and boat and drive on the beach. but can anyone verify for me tht is a tranny cooler.

There is a good possibility you have 2 coolers, as my 01 had. If looking underneath from the front and you see a cooler, it is the power steering cooler. If looking after opening up the hood, but in front of the radiator, that would be the transmission cooler.

Yes, your truck should have a tranny cooler. It is on the right side in front of the radiator as you mentioned. The lines run down the right side of the motor to the tranny.

Over on the left how ever, there is also a smaller radiator looking item. This is the power steering cooler. It is much much smaller. Trucks without a tranny cooler still have this, so you should see both.

Don't get too excited about that cooler...it is very inefficient except during the simplest of jobs. It does a good job of keeping operating temps where they should be under normal conditions, but that's about it.

On a side note...just reading your signature there, if you plan on getting 33" tires, you absolutely need to budget at the same time for new gears. 33's with those 3.31 gears will suck butt trying to tow ANYTHING.

Your tranny only has a cooler in the radiator because you don't have the factory towing package. The 3.31 gears were only available without the towing package, and your max tow rating is very low, probably around 3000# or so. If you are going to tow anything bigger than a utility trailer, you need a frame mounted hitch, another tranny cooler, and better gears.

yea i have a frame mounted hitch and i only tow a pop up camper tht is about 2500#s and a bass tracker thts about 1500#s but any way the truck gets the job done with no issues. it pulls them both fine. but we have pulled the camper on a 6 hour trip to myrtle beach and the truck was loaded down in the bed of the truck and the people inside and the truck barely squated. probly close to 4000#s tht trip and the truck did wonderfully and some of tht was stop and go due to traffic. i have never had problems with power on my truck. but i will change the gears eventually.

I would also add a tranny cooler. Get one from an F250 Super Duty (or something like it) and your trans will be way better off.

Any chance do those 2 lines run into some sort of module. ( 2 lines into what looks like a 2 inch by 2 inch by 1 inch alluminum block with 2 stainless lines leaving it.) or does this have someting to do with brake lines. Because mine are leaking at the fittings on this module block.

The module you are talking about is a thermostatic bypass. It puts most of the fluid straight back into the transmission without putting it through the cooler when the fluid temp is below the set point.

Try tightening the fittings on the lines to see if that stops the leaks.
