Trans Temps

[96WhitePowerstroke]

I am getting used to having gauges in the truck however I realized tonight that I probably should know a little more about what they are telling me.

I put in a system from GlowShift: Trans, EGT and Boost.


I am seeing about 160-180 on the trans temp. This is unloaded just the truck. From what I have read anything over 230 is cooking the transmission. Where is normal operating temp? I am going to be towing a 44' enclosed trailer with two race-cars.

EGT's - Around town I am seeing between 200-600. What kinda temps should I see when towing?

Boost - 10-15psi around town.

Just looking for ranges and have some idea when I need to back down.

Your temps sound about right. That's where mine run accept my boost runs higher. Towing I've seen 180 trans, 1300 EGT and 28 psi boost.
Is your EGT pre turbo?

Mike - I think I botched the setup - My probe is on the down pipe - I would say about 8-10 inches from the turbo. I was doing some reading (after install!!) and it said that you want it in the up-pipe on the drivers side. I wounder how far off my temps are ...

Any ideas?

I wish i could tell you the difference.
The first thing I did when I got my truck was installed an MBRP 4" exhaust. All it had when I bought it was a downpipe which had the pyrometer in it so I have no comparison.
Some guages like autometer tell you to install them in the downpipe. You could always get a pipe plug and move your pyrometer.

i woul dmove it IMHO. but general rule is add 200*F to what the gauge tells you if your setup is post turbo.
