4R100/gauge temperature questions?

Alright guys I just got my trans rebuilt a couple months back and while doing so I installed gauges (glowshift). Well my trans temps have seen 195-200 since the week I re installed it.....only on long stretches though...around town it stays around 180 after it warms up. I drove 60 miles one way yesterday and my temp got up to 220° but my stock dash gauge stayed under half ways.... i continued to drive it even at that temp, and hasnt slipped, no OD light, shifts are still firm cause of the shift kit. Temperature around here on average is 95°, but latley ot been around 100°. My fluid is full and not burnt! I guess my question would be...do you guys think I have a bad gauge? Or if that's even normal? Also I have the stock 7.3 trans cooler. Whats yalls thought? Thanks in advance! (I've read about "mark" saying 220° is hot but not cooking the fluid yet, not until 305°, so I've searched here Google and a few place"s)

When you had the trans rebuilt did you do anything with the trans cooler?

I blew the old fluid out and ran cleaner through it like the trans shop told me too. But that was just through the lines.

You need to add a 6.0 cooler to keep the trans temps down below 200 especially if you tow.

Re: 4R100/gauge temperature questions?

I used to have the same problem on my 02 7.3. It would run around 180 to 200 all the time empty but as soon as I would hook up a load of any size it would begin to overheat. It turns oput my intercooler, radiator and transcooler we plugged solid with dirt and mud. I took it ll apart, cleaned it up and added a bigger transcooler. After that even being loaded heavy in 100* heat it was hard to get my trans temp over 180. Hope that helps.

That's exactly what mines doing! And this crossed my mind cause I drive down 16 miles of county roads a day and these roads get DUSTY also I haven't washed the outside of my truck in a while. I just didn't think this was possible. I'm glad to hear it could be the problem! Ill give it a try, Thanks!

Re: 4R100/gauge temperature questions?

Just bought a 31 row cooler for $40. The truck I pulled it from was an 03 f350 and it had 76k miles on it, the company parked it cause the crankshaft had in/out play. Was this a good find??

Hell yea that was a good deal.

Those new are around $400.

Should cool it right off and solve your temp issues.
