installing Transmission Temp Gauge help

i've never seen a write up for a Trans Temp Gauge and it wasn't too expensive - $50ish shipped


my main concern is it like drilling into an Oil Pan for a Oil Temp gauge or is there any areas i need to avoid?


hoping its a straight forward install and any help is appreciated


install on: 03 - Accord - 4 Dr. - Auto - V6

I actually installed one on my 03 a while back when I added the cooler. Since I was already modifying the lines, I just added a "T" adapter in the line that the sensor could plug in to. Easiest way to install a sensor. I would not recommend drilling a hole in any part of the motor or trans to try and tap the sensor. Go to the lines.

Since you have a V6 you want a transmission cooler, not a heat exchanger. User t-rd installed one and it fixed his problems.

Scan gauge is great and all, but you need to KNOW what you are doing when you go into custom gauge territory. There are some custom gauges already figured out, but they don't always work. I had tried a cat temp gauge and a buttload of air to fuel ratio gauges and none of them worked.

when you say buttload of A/F Gauges, did you ever try the Wideband?

i know they are more than basic A/F gauges but mine works okay


i.e. before my J Pipe and PCDs, i was usually in "Optimal" but after...it says i'm running "Rich"...i'm fine w/that than running Lean


where did you tap the Sensor wire?...i remember having to tap a wire on the Pass. side next to the ECU

Scangauge as in this bad boy. You can PROGRAM custom gauges. Wasn't talking about adding another o2/afr sensor.

When I added my cooler and temp gauge, I actually bought a new hard line that comes out from the filter and cut it in half with a hack saw. I then filed the ends for any burs and added the new rubber hose lines to the two ends with hose clamps. So the hard line comes out from the filter and faces the front of the car instead of going to the back, has a hose connected to it that goes to the cooler, then another hose from the cooler coming back to the other end that was cut which goes to the back of the transmission. My temp gauge is "T" tapped in the return line from the cooler. Really wish I had tapped in the line going to the cooler instead so I could see what temp it was before the cooler. In any case, to me this was the easiest way to tap in to the line. Plus since I got a new line to modify, I still have the original one in case I need to change anything back.

I would not tap in to the radiator hose for your transmission temp. This will not give you a proper reading on your transmission temp. You already have a gauge from factory for the radiator temp.

thanks, much appreciated!...do you by chance have any pics of your set up?


that's my biggest thing...i want to see how much of a difference BEFORE adding the Trans cooler. I would think Temps would also vary during Winter/Summer? I don't do much rush hour driving but Members have stated improvement w/Trans cooler in stop and go traffic. Just wanna try and put some numbers behind it

Unfortunately I did not take any pics while installing it all. I'm usually doing the work by myself and don't like handling my phone while my hands are dirty. I got my Aspen shortly after the install and I've been driving it so she's been sitting for a couple years under two tarps so it's kind of hard to get pics now as well. Especially with the drop in temps and high winds we've been getting lately. Really don't want to mess it during this mess.

The four cylinder has an in line filter. Which would make it easier to tap in to. The V6 has the filter internally and is supposedly "not serviceable". Although many of us have changed it. To my knowledge with everything I've researched, the V6 does not run to the radiator like the I4 does. Which is odd as my wife's 2000 V6 does hook in to the radiator. I recently discovered this when I had to replace her radiator.

The pipe I modified is called the Pipe A (Atf). Part number 25910-RDG-305. Like I said, I bought a new one for like $40 and cut it just shortly after where the banjo nut goes through it in to the filter assembly. Turned it to face the front of the car and hooked up the other side as normal. Was a little tight to remove the old one and hook the new cut one back in. Then I simply ran two new hoses from each end with new hose clamps to the new cooler I installed. Added a "T" tap on the line from the filter assembly to the cooler so I could hook up the temp sensor. This was my only mistake. I should of done it on the return line from the cooler instead so I can have temps after it ran through the cooler. One of these days I plan on changing this. As it is now, if I remember correctly, I was seeing temps of about 120-140. This is in the hottest days of Texas heat. Again, before the cooler.

V6 does NOT have an OEM cooler running to the radiator, it only has a hockey puck like warmer.
