danny,
the challenge with your question is that the accuracy of the vdo gauges on the dash is questionable at best. the temp gauges are non linear and at least on my previous 90 newell with the 8v92, highly inaccurate. they become more of an indicator of temperature trend....
the vms pc that is talked about hooks into your detroit ddec engine control system and reads out exactly what the temp sensor on the engine is giving the engine controller. that is what most of us use. i used it on my 90 and i use it on my 02.
the answers about temps are also different dramatically between the 8v92 you have and the series 60 that others have. i have had both. i was much much more concerned about engine temps on the 8v92. the rear mounted direct drive fan radiator setup is far inferior to the side mounted hydraulic 2 speed fan on the series 60 newells.
that and the 8v92 reacts far more harshly to overheating. most that have the 8v92 start to have panic attacks with the vmspc starts reading above 200 degrees. at 205 michael day starts hyperventalting....ha
your tranny temp of 120 i would guess is suspect as michael said. it is too low.
the piece of mind of having the custom digital dash from the vmspc is worth the 400 bucks or so it costs.
when you toast a 8v92, there are cylinder o rings that melt and put coolant in the oil. becomes a no fun situation pretty quickly
the 8v92 is a great engine. just needs to be kept cool. in trucks, and other coaches they had i believe a better cooling setup than newell did on them.
that said, many have no issues ever. but all savy owners keep a close eye on engine temps.
