If you watch the scan guage temp, the trans temp goes way up if you a running a steep hill in too hgih of a gear (even when in drive) or in high range. You'll also notive the factory coolant temp guage sucks. It won't budge between 175-215
Yes, factory coolant gauge (non-modified) in both the 80 series and 100 series has a big 'dead spot' in it.
Well known to most MUD members. That is the reason I put a ScanGauge in both of my vehicles to start with.
But for my 80 series...I had to do something different in order to monitor the trans temp.
The Oil pressure gauge (factory) is another thing that would lead one to believe they have little to no oil pressure at idle. Just some of the well known quirks about these vehicles.
The Trans temperature will rise anytime the Torque Converter is not locked. Doesn't matter if you are going uphill or not...though that makes things worse.
