transmission temperature

[JPR]

What is the recommended operating temperature for the transmission?

I am thinking about going with a cooler mounter under the floor of the cab with a thermostatically controlled fan. Due to the intercooler install, I had to go with a smaller transmission cooler. Yesterday it did not seem to be keeping up in 70-80° weather with strong head winds and a trailer.

Remember that the internal temp could be as much as 150° higher than the pan temp.

So find a temp switch in the 100-140°F range?

My thought is to remove the extra trans cooler in front. Then add the hose connections to the transmission pan for the new system. Either this cooler or a similar home made system

sounds like you have got that figured out now just finding a fan with a switch or changing one out to get the correct temps will be the trick. hope you and the family had a pleasant trip and Thnaksgiving

DON'T remove the factory cooler! Auxillary coolers will augment the factory cooler, but they cannot replace it. Leave it there and add whatever you buy to it. People in the past who have dosconnected the factory cooler had problems to no end with heat.

I was planning to keep the lines connected to the radiator, just removing the small aux cooler that was mounted in front of the grill. Currently it is tucked between the radiator and the intercooler below the a/c condensor. A very tight fit.

Oh You already have an aftermarket cooler. Why don't you just relocate the aux cooler you already have? Maybe no fan, but if you put it in a place of high airflow it may help alot more.

I could not find a place big enough for the plate type cooler that I just removed in the nose of the truck. I had to trim the grill just clear the intercooler and the receiver hitch prevents placing it behind the bumper.

I saw a pic once of a gm pickup... the owner put two coolers over the cab mounted to the headache rack ;p Plenty of airflow. And large fast moving articles

Napa makes a relay setup with a temp probe(installs thru the primary radiator fins), can't recall the #'s. Had to put one on my 88 Ranger 351W conversion. Had same problems no space and too much heat. The relay worked well as it has an adjustable pot dial and could dial it in to turn on a fan at a large variation of temps. Location is definitly a problem with all the goodies up front and is the best location for air flow. I opted for the side framerail at one point but was too concerned with road debris and couldn't get enough air flow.
Chickened out and dropped in a toploader 4 spd. No more cooked autos.
Final auto in(3rd) lasted 1200 miles and was a worked up C-4.
Now I just use the relay for the primary cooling system.
Too much

Ramon - trip was nice except for the stop and go traffic on I-35 including multiple accidents on Sunday.

Ron - even if I swap to manual that is in the garage, I will still need a trans cooler (it is 6 speed).

I've eliminated both the radiator trans cooler and the factory air trans cooler. I replaced them with three 15,000 B&M stacked plate coolers. I mounted them 3 across right behind the grill. The trans has yet gone over 150 degrees. Of course, I don't have an intercooler, so I can mount them in the for optimum air flow. I would strongly reccomend that you add additional coolers in the transmission lines, as opposed to trying to cool the fluid in the pan. You could add a deep pan with cooling fins that run through the fluid if you want additional cooling through the pan.

Acording to Brian at BTS, I got a Super Duty Tranny cooler and mounted it behind the bumper cutouts.

Clicky here

He said "that is all the cooling that you will ever need".

It is running through the Rad. first, then to the aux cooler. Never had a problem according to the tranny temp guage. allways stays

gotta tell ya guys,when i had my reman jasper e4od installed it came with the extra cooler,i installed a 140 to 300 degree gauge,and i have only had it hit 140 one time pulling a trailer in 100 degree heat.
the other day i used one of those infered heat gauges,and it read 130 degrees at the pan,no trailer or load in bed.
