seems like the outside temp really dictates alot. just got back from camping at evergreen lake about 20 miles north of where i live (allentown). going there temps (outside) were close to 88 and tranny temps stayed about 180-190. coming home outside temps were 68-70 and pouring rain. tranny temps stayed right at 165. did alot of hills and all back roads. actually kicked the truck in the *** just to see how it would react on some hills. when hitting 3k it really pulls well and kept the speed on the steep hills. i usually keep the rpms down to 2k-2500. decided to see how it worked pushing it a little bit since the rv magazine did a peice on the titan and a similar sized tt as ours (weightwise). anyway thought i would keep you posted. all is well, except back to work tomorrow! LOL see ya.

 

I've been thinking of getting a TT myself and was wondering how you like yours so far. What size and weight is the trailer? Did yah do any other mods to your truck beside the tranny gauge? Thanks.

 

Good to see some numbers on the trany temps. Your runing about the same as me. Here in California its been running tripple digits every day for the past three weeks or more. Mostly 100 ro 110 daily. Driving around empty on flat ground I have been getting to about 165 F and then I did a good climb in the heat and hit 195/205 F. with outside temps at the same level. If I go out in the late afternoon or eveing when its down to 85 or a bit lower I run at around 150F. BTW, the humidity is running very high at around 80 to 95%.

Now to do a test later with my TT on the back end. I also should mention I am runing e-fans too.

the tt is about 7200lbs. only factory tow package, nothing else done. i have a 1500lb blue ox wd/sway control hitch that works great. only got to the 210 mark for a short time going up an 8% grade on some steep back roads in north central pa. the outside temps that day were 90-95 degrees and very humid. most of the trip that day was averaging 190. i just wanted to post how outside temp really makes a huge difference! take care.

forgot to answer your question. the tt is a 29 ft sprinter by keystone. it has fiberglass shell with aluminum frame. has one super slide. hope that helps. oh, on the way up i was actually full of fresh water (40 gallons), so that added to the weight big time. coming home i was empty but gauge hot wire not put on correctly so i didn't get to monintor that day. moral of the story, do it right the 1st time! LOL

How are you guys getting your transmission tempetures? Does the ScanGauge give you this info?

 

Autometer Tranny temp gauge installed in a dashpod. You know, up on the dash in the center tray. Got a voltmeter up there too. My scangauge does not read transmission temps, just engine coolant temp.

By the way Jim, I got the shorter sender unit and I will change out the orignal and see if there is any difference between them. Maybe get to it this weekend.

 

If the sender that came w/ the gauge was working, why did you order the shorter sensor? If you've already made the change, was there a difference? I'm curious because I'm going to put my gauge in this week end. Also, when you remove the line plug does tranny fluid leak out?

 

yes it will leak but I do not know how much as when I pulled mine I had the sensor ready and poped it in right away and only lost a small dribble. the hottest my trans temp has gotten is 193 and that was when it was arround 100 out. my temp seems to run arround 95 degrees above the outside temp in normal driveing not towing. towing is about 10 degrees warmer unless I climb a hill.

 

So at what temperature on the tranny gauge do you say its time to pull over and give it a rest??

 

that is a good question I was wandering the same thing.

 

So....at what values do you say it's time to take a break and give the tranny a rest. Here's the scenario.....your towing up a long hill, you got the Live Link up and running showing you tranny temp, speed ratio, slip of the converter. There's a pull off half a mile up the road and your not sure how long this hill is. If my values are below ___fill in the blank___ I can keep going no worries. However, if there getting near or over this level I should pull over and take a break. Where could I find these "danger zones" if you will so I can use my gauges properly.

In other words, why install a gauge if you don't know what your reading.

 

I've heard above 220 or 230 degrees is where to start getting concerned. If you normally drive the truck you should have a decent idea of where the temp is normally, both towing and not towing. If it starts running higher than normal at least you will know and can have it looked at if you feel it's necessary.
