Not to steer this thread a bit sideways but what is the "ideal" trans operating temp of a 26' with 403. 26' with 455 and the same for the 23' units? I'm not a "gauge" guy but do see some value in having this one providing i know what i should be seeing on the gauge.....
Good question, so i did a search. The broad general rule across a bunch of transmissions, according to random people on car forums is 180-210 - same range as the engine.

And there is broad consensus that the cooler it is the longer it lasts.
