Transmission Temp Gauge and Boost Gauge Install?

SilverBullet21 · 08-09-2007, 02:03 AM

Newb here.....Anybody have or know of a good write up on how to install a temperature gauge on a 2003 48RE tranny? Boost gauge? I looked in the 3rd gen. tech articles but couldn't find one. (may have missed it). Also tried google and no luck. Finally got the gauges in and not sure where to put the sensor. is the install an easy tap in somewhere or would i have to drill?(drilling scares me haha) thanks for the help.

boost gauge is too easy you'll replace one of your intake bolts with a boost bolt hook your lil rubber line to it, and be done
I saw a neat way to hook up your trans temp without drilling DieselManor - Taking the Mystery out of Diesel Performance™ has a replacement transcooler line with a place to screw in your probe built into it...other than that you can drill your stock pan or buy a Mag HiTec pan...that's what I'm going to do.

We carry fitting to splice into the rubber hose section of the hot line to mount the temp sender. As for the Boost gauge, boost bolt, a hollow bolt, is the easiest way to install one.

I apologize...let me amend my advice...check with sponsors before you go lookin' elsewhere...the sponsors actually care others may not.

On my 07 I purchased the gauges from Geno's and they have an adapter called the Acu Temp Adapter. The temp probe screws into the adapter and the adapter has a groove that fits over the hot cooler line. Works great no cutting, replacing any lines. In addition, if you buy the boost gauge from them they supply a boost bolt free. Sorry I see now that you already have the gauges, anyway check Geno's garage for the Acu temp and boost bolt.

Diesel Nut can get ya going!!!! :thumbsup
I used the replacement cooler line from dieselmanor, before talking to dieselnet, and it turned out to be a bit more costly and time consuming than i planned (I drained/spilled out almost 5 quarts of ATF the hard way... ) - it works good and is very clean looking, once it is installed correctly!

DieselNut, is that a "vampire" type fitting to rubber part of the cooler line for trans temp?

Just a suggestion here. As for the Tran's Temp, Additional fluid capacity and Cooling is a bonus with the auto, you may want to consider a DD pan and put the sender in it.

This is what I made up to tap into my hot line for a Stewart Warner trans temp gauge. I plan on having a fun weekend with it.

This is the one we use.

If you use hose pliers or needle nose vise grips you can limit the amount of oil that drain out. You will have SOME drain, no way around that.

Also if you let the truck sit for about 12 hours (over night) most of the fluid will drain to the pan and there is minimal loss.

I had good instructions for replacing the cooler line (thanks diesel nut), but figured i knew better after seeing the cooler line was connected higher than where the pan bolted to the tranny. after i removed the cooler line, I only drained about a quart from the line, but then almost 4 qts from the (cooler line hole) in the tranny about 2 inches from the pan line...
didn't know there was that much fluid in the trans ABOVE where the pan bolts on. i thought the truck was "level", but i musta been wrong!

guess it never hurts to put fresh atf in there, even if it was only a month old...
