has anyone actually drilled and tapped the stock trans pan for a trans temp probe ?

 

The gauges you install will be more acurate than the ones on your dash. Iwould not worry about doubling up. Tranny temp, oil temp, water temp, picture of your wife, whatever.

 

i though I was the only one that had issues seeing around my a piller

 

i've never really had a problem at all with seeing around my A-Pillar as it is now.

 

A vacuum gauge can diagnose problems in their early stages
and by watching vacuum (it is just 30-MAP)
on flat sections, downhills, and hills
you can learn about how your gearing is set and what potential
gains you might get with different ratios.

An EGT gauge is useful if you intend to increase airflow with cylinder head, valve, throttle body changes or camshaft changes with the Ram's speed-density computer system.

Even more useful is a wide range O2 sensor if you intend to make large improvements.

It is sad to admit it
but a oil temperature sensor and gauge
for the troublesome 9.25 differential
might give a warning and save money
if the pinion bearings or the oil seal in front of them fail.
