Is it low on fluid? Is it overfilled? Either one will cause it to run hot.

the fluids are at the right level. i was just on the highway, looked at trans temp and said 125 deg. like 10 min later i took a quick look at it and it was at 220. from a cold start and running it takes about 15 min for it to get around 200 deg.

Dan -What brand of gauges do you have? I recently had a similar problem w/mine but mine was bouncing erratically. Diesel manor is sending me a new amp box for it.
