How far are you driving? A short distance and it might not warm up.
Since the gauge is functional, and the wiring apparently is alright to the gauge (I assume that's how you grounded it), I'd check the wiring at the sender to make sure it's tight, then check the sender itself, perhaps the wiring was stretched or the sender damaged during the valve body work.

Still...granted different vehicles, but I've got tranny temp gauges on both GMs and they warm up even on the coldest days. It can take a while to get them warmed up though, especially if driven gently and not loaded up at all. Both have shift kits though, so that might contribute.
Does the gauge bottom out at 100*? If it does, it should definetly have gotten over that long before you got home.

I'd say something was up then. I have gotten the Sierra and Silverado both up well over 200* on hot days towing a load.
I'd be suspecting an issue with the sender.

Location of the sender is important. It normally goes to the trans output to the cooler line. This will be your hottest point. Ideal trans temps are 170*, no more than 190*. Excess heat is what kills most auto trans. jd

It's not stock. You can get aftermarket ones from any of the major manufacturers, Autometer, SunPro, IssPro, etc. No reason for you to get one JeremyJ, they're not really helpful on manuals, the temp is much less of an issue (more durable and less heat produced since no torque converter).

As are both of mine. And I can hit 200 on a hot day. It should easily be registering on the gauge after a bit of driving.
I'm still leaning towards the sender. Perhaps you can use a laser thermometer to get some temp readings.
