Towing and my transmission

[LilGuy21585]

well for my automatic transmission iv always been under the impression that 170-180*F was ok but then i heard 150 was the max, it should never go over.... in that case then im here to ask the question what and how is the best way to reduce temps. im looking at a trans flush this week since temps went to 200*F while traveling any wheres from 75mph flat to a slow and steady decrease to 55mph (gracfuly not tryingto keep 75mph up steady grades) i have never had much time to look around on a few sites but now adays thers more chip and programer addvertise then any redime products to solve the head aches that come with the "so now uv got the chip" ordeal any help would be great and im sure i can return the favor in the future

200 is ok no need to flush fluid unless it smells burnt. 230 is about max temp.

you can pretty much expect your temps to be 90-100 degrees above the outside air temp

150 degrees??!! If that was the max than I would be in serious trouble lol. I always heard 220 and pull over and let it cooldown.

[LilGuy21585]

txs guys i guess i have "babied" my truck then... max i have ever been up to is 210. thanks for the info guys

230 pull over
200 entering red zone
180 is fine
150 is great

all temps are dependent upon outside temperature. If ambient air is 100* and you're running 190* there isn't much you can do... you're going to run 80-100 degree's above ambient temps.

I agree with the numbers above, mine usually runs less than 140 on 100 degree days unless I have the AC on and towing and in traffic, then it may get to 180. I have 2- 40K trucool coolers in series. They are about $120 each.

Is there a standard place for the trans temp sending unit? I'm new to these trucks, and would like to know if there is a "stock" location, such as a threaded plug, just a matter of threading in the sending unit? Also, if locations differ, is it possible that's the reason for a fluctuation or lower readings in 'LilGuy's' truck? I've never had a trans temp gauge on anything, (it will be one of the first I add to my new(er) F350) but it would seem to me the lower temps would be ab-normal, or just the sending unit getting it's info from a cooler location in the trans.
Just my thoughts, I'm new here... thanks for your time!

Yeh there is a port in the side - it's just a plug you un screw.

It's on the side of the tranny, forward the black box with wiring, on the driver side.

If you come to the North carolina meet and greet - I'm sure we could get gauges installed no problem!

[LilGuy21585]

well i was thinking the same Dieselcrawler, i have and edge old style evolution thats where i get my temps off since my att & juice dont display it
i too was woundering where that wire or sensor might be when i get time ill have to look throught m haynes book if it in there.
but for me .... id like to find a digital read out.

you might consider a tranny cooler as well. i have on myself. on a bad day, i will see 180 unloaded.
