False overheating
I saw a thread here not to long ago about a guy who was having a false reading that his truck was overheating. The gauge would climb but the engine wasn't actually hot. Somebody mentioned that the voltage regulator for the gauges could be going bad.
Anyway, I think I might be having the same problem now. I'm not sure what the cause is yet. But if So, where is this voltage regulator and how do I go about testing it?

Right now I'm kind of suspecting a sticking thermostat. Temperature fluctuates between 200-210. But never gets any hotter.

IVR part number for 71/72 Bumps was D1AZ10804A. Mounted on the back of the cluster. You want me to run it on the Ford locator or you gonna buy one where you used to work?

I'll find one if I nail down that thats what it is. At first I thought so but I've measured engine temp a few different times now and it is actually running warmer.
It seems very odd that it starts doing this right after the tranny install. But the trans is always right at about 180. I don't know what's going on. It's just bugging me.

Haha, false alarm guys. I figured out what was happening. When I swapped the tranny I forgot to hook the ground strap back up. The one that goes from the firewall to the bellhousing.
So it was my fault...

My temperature gauge would always warm up with the engine and then peg a hard right indicating an overheating issue. I don't remember seeing a ground strap when I pulled the transmission, or now that the front clip is off. Maybe I had the same issue?

Possible. The strap in talking about goes from one of the upper bellhousing bolts to the firewall right behind it. Just an open/bare wire strap. If there wasn't one there, I'd recommend installing one. Even though the truck works without it, it does these kinda things.
