Trans Temp

[Mikes7.3]

What is your trans temp gauge reading? Average everyday driving and towing.

[sirnunya]

Daily driving 130-150. I've seen it as high as 175. Don't know about towing really..

I have seen 185 on mine for a short time pulling the RV up a 6 % grade. I backed out of it and it started to fall real soon.
Just driving arounf town it's at 145 to 170

well before my tranny upgrade i was seing at the most 160 while towing but now after the tranny rebuild i easily see 160 on every day driving... ive gotten as high as 190 on a hot day so my next mod will def have to be a bigger stock tranny cooler and a secondary cooler as well.....

I have a late 1999 F350 crew cab dually with the 7.3 PSD.

I see 140-160 degree usually empty. I also see the same temps towing my HUGE 5th wheel toy hauler at highway speeds. I get much higher temps when in stop and go traffic when towing, especially in hills. I have seen 200-210 for brief periods.

I am going to install a larger fluid pan, supplemental cooler and fan. Anyone have any suggestions on these parts?

I am thinking I will get a remote transmission cooler and fan that mounts under the bed and also put a supplemental cooling fan in front of the radiator to help with the radiator and a/c cooling.

There are alot of aftermarket fans and coolers out there, just wondering if I could get some input on what you guys are using.

Just add a 6.0 tranny cooler and be done. You dont need a bigger pan, just makes more hot fluid to cool. You dont need a fan to keep it cool. BTS installs a 6.0 cooler, a 4x4 pan, and delete the bypass valve. Thats what I have on my truck and I have no issues with tranny temps pulling some of the biggest passes in the NW.

Normal driving you should see about 50-80 above air temps. Pulling that can go up, but your fine running temps up to 225 for any amount of time. Get to 230, ya should pull over, put it in N and idle up until they come back down.

A TC lock up switch helps tranny temps A TON. Keep it locked above 28-30 and you will never really see hi temps.
