Tranny Temp.

[Burnin Coal]

My transmission seemed to be running hot this evening. My truck is a 2000 F-350 with an automatic. Having only owned this truck for less then a month I know nothing about it's history but there is paperwork in the glove box that indicates that the transmission was replaced with a Ford transmission and the tranny is definitely cleaner then the rest of the under side of the truck. Unfortunately I have no idea what model the tranny is so if you could enlighten me on how to find that out it would help.
The tranny temp gauge has never gotten above 150 but this evening while just casually driving around town, no hot rodding, 67 degree outside temps it got up to 180+ .
What is a normal operating temp and what might be the cause of this much temperature rise.

Yeah something is going on with your tranny thats for sure. These things need to stay cool and maybe when they replaced the tranny they didnt flush out the tranny cooler and lines so they might be plugged up abit. Another thing is really, if your gettin that hot running down the road empty, thats not good.

I towed 4 quads down in a 16 ft enclosed with everybodys gear along with a bike in the truck, half load of firewood and anything else i could shove in there. It was prolly close to 60 out that day, and my tranny never saw 160 at most. I would get it into the shop and have it looked asap, i would say you got something wrong. It might be major or minor, wont know until you have it looked at.

I agree tranny cooler and or all lines might not have been flushed. I had one done before cuz I wasn't able to do it myself at the moment do to time and took it to a shop they didn't flush the lines or at least not properly and I had to change the tranny filter 3 times in about 5k miles so I would have it checked for sure. I can't remember off the top of my head but I'm sure my tranny has never seen over 165 hot ridding it and all I don't think it's even seen 160 to be honest but idk at the moment

Where did you guys tap in and put your trans temp sensor? I have the factory gauge on my 2002 but would like to install a real gauge and get actual temp readings rather than the "normal yellow then red". Hope this goes with the thread, not wanting to highjack ya here. Thx
