Default B&M # 80212 Trans Temp guage Install on 99 XJ

Ok, I just installed my trans cooler by B&M. Needed some additional hardware so it prolonged the project but luckily had family to help me out with what I needed. Finally got that installed and it's all good.


OK, got the package from the Fedex guy. Picked it up from Streetsideauto.com. I had a gift certificate for $25 so I took advantage of that. (My version of extreme couponing ) They had it shipped to my door in 1 day.

Here's what you get.....





Coupling and sensor



But the morons forgot to tap the threads. How does that work?





This is how it's SUPPOSED to be hooked up.



They decided to give me 2 green friggin garbage bag ties for no good reason though.


I had some fittings and stuff left over from work and if they were just a tad bit longer, it would have worked.




So, for now the job is put on hold and I barely got past checking to make sure all the parts were in the box and the other reason is because it's now 10:30 at night.

To be continued........

Ok, time to continue......

Well, today was a much better day. 1st thing was to tap the coupler that wasn't done by B&M.



Got out the hole saws (thanks again Dennis!) The correct size is 2 inch or 51mm.





Now it was time to figure out where I wanted to mount it. I tried a few different spots but ultimatley put it where I have seen them mounted before. I didn't like it anywhere else. I kind of liked it near the gear selector but there isn't enough clearance underneath for it.

Now that I figure out location it was time to start ripping stuff out.

Emtpy out all your crap that you forgot you stuffed in the center console.



Start taking the center console assembly out. It's easier to put the 4wd selector in 4 hi or 4low and put the emergency brake on to slide it out over the handle. Also remove the center dash bezel (goes around radio, vents, AC/heater controls ect..)

Double check your hole saw to make sure it's the correct size and install it on the drill to make sure there is no wobble to the center bit or hole saw blade itself



Trace out where you'd like your guage to be mounted and find the center to make your 1st drill







Looks good.



hook up supplied nuts to hold into place with the supplied bracket.



Run the wiring accordingly by following the directions that come with the guage. These directions are very detailed.

I hooked up my wires as following

Sensor wire- obviously routed to the sensor on the trans line (coming later in write up)
Ground wire- Mounted underneath 10mm bolt that holds the shifter assembly to the floor
Ignition wire- To positive wire to left side lighter assembly (Only has power when key is *on*)
Illumination - ran wire off of 12v positive for indicator light to gear selector assembly



Once that's done, install the center console and get ready to wire it to the Jeep. I installed these connectors because I figured it's a Jeep, this won't be the last time I'll be working on something inside. So this will be an easier way to disconnect and reconnect everything.



I wasn't sure which lighter ran off the ingition only so I tested and ran the ignition terminal from the guage to the lighter wire.

I ran the ground wire to one of the bolts that hold the shifter assembly in. you'll need a 10mm socket to remove them.

Start to button everything up.



Reinstall your CB if your vehicle is so equipped.



Now admire your work



Start wondering why you keep burning body parts getting in and out of the Jeep.



Ok, time to run the sensor wire

I ran mine through the fire wall and stole some real estate already available to hide the wires.





Ran the wire around to the passenger side and tied it along with the wiring to the alternator.





Set up your fittings with teflon tape, cut about an inch or so on your line. I used the supply line from the trans to get actual temp not cooled temp.

Hook up the wire to the sensor and remount the holding bracket. You're all set. Run the Jeep in gear holding the brake for a few minutes and then let it idle for about 10-15 minutes. Check for leaks. Take your new trans temp readings and enjoy.





Now, go count all your change you had in your ashtray. I had 16 bucks in there!

great walkthrough!!!

I need to do the same...I am weary about wheeling with autos. I burned up the auto in my F350 a few years ago after a day of wheeling. Not fun.

Nice Write-Up, and Awesome location for the gauge!!!


Now... just gotta ask, what kind of temps are you running now with your B&M SuperCooler installed?

awesome, i will be doing this same thing, i was thinking about welding a nice little bung in my trans pan but this looks MUCH easier. my only worry is how accurate it really is being that far away from the trans its self. i know that just popping my hood and driving down the road on a hot day my jeep tells me before hand that it was hitting 210 220 for the coolant temp. then after with the hood popped it suddenly dropped to under 190. so.... wind apparently makes a big difference in how the sensors of this style read.

Thanks man!

Temps vary depending on load obviously but.......
On the highway (long distance) it stays in the 160-170 degree range
Normal around town driving it stays about 180-190 degrees
Wheeling, I've only had it above 210 when climbing part of the mountain at Rausch Creek but otherwise I never have a problem keeping it under 195 on the trails.

Sorry it took so long to answer you. I didn't know you posted to the thread. I didn't see the notification.

Thanks man. Yeah, I did alot of research before purchasing the cooler and glad I did. It works better than expected. It's not necessary to get the guage but it's nice to have. I'm just a nut when it comes to stuff working right. I like to see what everything is doing. My Jeep would look like the cockpit if I had the means to do it. I have LED's to let me know when my rad fans come on just so I know they are working.

I was concerned with the wind hitting it as well. Where the lines mount, they are pretty close to the block, there's enough to block air flow in that location. If anything, it would get hot air from the fan cooling the radiator. It's not that far from the transmission and it's taking the reading right before it comes out of the transmission so that's pretty much as close as you're going to get as far as an accurate temp is concerned. If it gets hotter at the transmission, then you have a larger problem than the cooler.
