/diy/ - Do It Yourself

I need some kind of temperature sensors for the drivetrain of my school bus motorhome since the gauge cluster is not working and it only displayed oil temp anyways.
as you can see in picture the transfer case is turned 90 degrees and its a real concern that the fluid might not reach the gears or not splash enough to keep them cool/lubed.
only the rear diff is oem, the rest of the drive is from a 7.3 psd

idealy there is some kind of temp monitor with 3 channels (tranny, transfer case, rear diff) or more (oil, coolant) all in one screen and not costing a shit load of money
