okay guys sorry if this is a stupid question , but as i was working on my 95 12v, (its on an engine stand) i was looking at that big water to trans cooler and i said thats just a waste of space for my future twins , so i pulled it . im going to be putting on a new performance style trans cooler and figured i didn't need the water to trans cooler unit , but im not sure if really need it, please let me know what you guys think, and has anyone here done it? also just in case yall wanted to know, the truck is a daily driver with very minimal towing and minimal dragging. no pulling.
thanks for any input.

Just move it. It helps heat the trans in the winter and cool it in the summer. I still run it on the race truck because it helps cool the trans between rounds.

does anyone else have any more input, would it be okay to run with out the cooler?? let me know your ideas/reasons to use or not use the water to trans cooler.

I tried to run with out it on my last truck and it was tough. I had to mount another fan mounted cooler under the bed and even though both coolers were the B&m super coolers with the LPD on a cold day it didn't want to warm up. For cooling on a hot day you would be amazed at how efficient that oil to water cooler is. On this truck I mounted it roughly where Brandon did and am much happier with the set-up. My vote goes to keep it.

 

I'm with both of them ^^ Mine is coming off and getting relocated , not sure exactly where i will put it yet , but i will think of something.

Brandon , what did you use to connect to the aluminum lines coming out of the stock trans cooler?

 

My DTT builder says to always keep it..

Jegs PN# 799-639230 - Have to be careful and trim only the flared end on the stock line. We've run these on 3 trucks now and haven't had an issue with leaking or blowing off.

The cooler does more to keep fluid temps up in cold weather than it does to keep them down.
I feel that in Calif you can easily get by without a cooler.

 

That's what i was worried about , and why i asked, do i need to use AN fittings? Brass should work i would think , there isn't alot of pressure in the cooler lines.

 

well i read what infidel said and forgot to mention that i do live in CA, and temps were i live only get to maybe 30 degrees at the coldest and in the summer they get up to 110 degrees. don't know if this makes a difference but thought i would let yall know. thanks for all the replys.

Which auto are you going to use? What is your planned driving habits?

The 90 comes with a non lock up converter. The fluid coupling is much better than newer (locking) stock converter, but you will still heat up the fluid if you do a lot of city type driving especially with a heavy foot.

 

driving habits are, mostly like an old man, with the occasionally smahing of the throttle to pass someone or blow a little smoke, i will install a trans temp gauge to monitor my tranny, i will be useing the 1990 727 tranny. thanks

FYI, for anyone interested , a transmission heat exchanger off of a 2000 peterbilt , w/C15 cat , and an 18 speed eaton , is much smaller physically (slightly longer though) than our stock heat exchangers, and it already has JIC fittings on it , no need to adapt pipe thread to JIC , they are #8 JIC also so they will flow a very good amount of fuel , they use 3/4 hoses for coolant , but the new ones come with an adapter from 3/4 to 5/8 hose.

Expect to pay around 375$ CDN for one though.

 

Keep the cooler. Mines at the same spot as Brandon, I just used 1/2 heater hose. My truck isn't as fancy as Brandons. The oil cooler/heater cools and warms-up the tranny on cold and warm days. If you don't run the cooler, get an electric fan tranny cooler and a good tranny temp gauge. I would also replace the stock tranny cooler with a big as you can get tranny cooler. My tranny gets hot towing up here in the great white north, imagine in 120 deg towing a 20k trailer in some hills in sunny smoggy caliy.
