You have a viscous fan clutch, they are always on, lock up varies based on the heat that flows across the unit.

you don’t want anything that is contant power…just keyed, unless the draw is so small as to not drain the battery. You can just pull directly from the rear battery…but that could and can degrade the rear battery. Not sure why you need this temp gauge, but its You’re truck. The TOT is readable on...

thats great, except your truck is 24v….you can wire a relay to be activacted upon turning The 24v ignition with 12v on the other side, or if you have 4 speed truck you can tap off the 12v feed to the TCM at the transmission relay.

A “good” transmission shop should be able connect up the TCM with the snap-on Diag tool and take the place of the TCM, my shop does/did for an issue I had…the TCM in the box is nothing special and with the schematic, a good tech can make up a quick harness to interface the tool to the plug, it...

The clutch pulley was designed to take the stress off the generator shaft and all if its mounting components when The truck is Turned Off, also to allow the gen shaft to freewheel when the rpm’s spikes And the gen shaft times to catch up to the other spinning fixed components. not uncommon to...

Just buy the bolts in stainless steel, I try and use SS socket cap bolts on all the turrets I install and sell. also, apply a sealant on the bolt before you insert the bolts, that’s how the factory does it.

You Need a drier and condenser.

50/315 is not correct…look at an ambient OAT to see what the LOW/HIGH should be.

I don’t believe the filter can be installed correctly without the separator…..the separator is all plastic.

I wish folks would research what a shock does as opposed to a spring….i promise you, on a Hmmwv you wouldn’t notice a difference if you just ran 0070’s, 71’s, 72’s or any other shock, it’s the springs that make the difference in ride quality.

Here is a working Catalytic converter

Black smoke is excess burnt fuel, white smoke is excess unburnt fuel. black smoke is generally a bad turbo or clogged Catalytic converter….a once a week affair in the shop. here was last week

Turbo trucks use the cannon plug version of tach, the signal comes from the generator, the 5 wire tach gets its signal from the tach drive that has a signal generator for the ste/ice, that signal generator may now come from the STE/ICE frequency converter Used on turbo trucks.

And what model truck do you have?

every TPS I install is just bolted on and set midway…generally in the same spot as the one I took off. ive had the them just plugged in and laying on top of the pump and the truck shifts fine…

till you get the transmission shifting accordingly, the TCC is on the bottom of the list…these issues work themselves out many times when you fix major issues, TCC doesn’t happen till you are at about 40-45mph and off the accelerator, that’s a separate test, and 99% of the time the brake switch...

But of course you can drive without a TPS, but you will get funky issues, at my shop, we fix issues, we don’t bypass them… last time I had this type of issue, the TPS was wired wrong near the fuel filter where it plugs in the harness, an hour with a schematic and a meter? I had it fixed as 2 of...

Remove the snout, and swing it to the side…much easier to work it.

There in NO 5/16 hose anywhere on a hmmwv….period. all transmission soft lines are 3/8, the only other size used is 1/4 on the fuel injection pump from the fuel filter and on the fuel tanks return.

Just what does “not shift well” mean?
