I guess I should write up my transmission temperature gauge then. I installed it for exactly the same reasons that you listed. It *may* have helped me prevent transmission damage once, and has certainly helped me "sleep easier" especially when the transmission heated up that one time. I have since then installed a transmission cooler.

I'll work on a real writeup, but the hardest part of the install is mounting the gauge.



Mine was installed by hacking a Mustang II pod to fit the Trooper A-Pillar. They may make a pre-formed pod for your truck. I plumbed the sensor into the pressure line from the transmission. It is 1/8" npt, so a t-fitting and 2 appropriately sized barbed fittings and hose clamps finished off the plumbing. You can locate the host from the transmission by tracing the hard metal line that exist closest to the front of the transmission. The return line connects to the transmission further back in the vehicle.

While installing this, be VERY careful of leaks when doing this. A dry transmission will last far fewer miles than a hot transmission. This is also a good time to install a transmission cooler if you so desire. This would be plumbed into the return line for optimal performance. Also be sure to check and refill the transmission fluid after you are done with either of these procedures.

I'm still interested. The place where I had planned on mounting gauges isn't idea. It only has about 3/4" of clearance behind it, so I'd have to find some low profile gauges. The other option is to remove the cubby hole in the lower DIN sized radio slot and put 3 gauges there.

If I could fabricate things out of plastic that didn't look like old dog toys, I'd make a panel to put where the ash tray is and put two gauges there.

I just installed my gauges in the VX too.

Oil pressure, volt meter and boost.

The oil pressure sender threaded in where the old idiot light sender was, and the idiot light sender is now where the 5mm plug was from the factory. Very easy install.

If you can keep a secret, I'll tell you that I didn't use an adaptor. 1/8" BSP and 1/8" NPT are close enough that it threaded right in. I even tried a 1/8" NPT tap in the threads first, and it didn't cut a single thread before it bottomed out. So I wrapped the sender in teflon tape, threaded it in and was good to go.

As mentioned, I did have to move the factory sender to the top hole, and install the new sender in the bottom hole.

Yes, I was referring to the transmission cooler line.

As I recall, the oil filter housing is 1/8" BSPT, not 1/8" NPT. Honestly on my VX I just threaded in the 1/8" NPT sender with teflon tape on it. Yes there is a difference in threads, but at 1/8" it was close enough that I couldn't tell the difference. It seems that there's enough variation in the precision of NPT from different companies that at that size it's a wash, but if you're a purist there are adapters available.

You should add a few more for that airplane effect:
