looks like you took a wrong turn somewhere… Lets start with the first pic. That large connector just inside the drivers door is the STE connector, stands for Standardized Test Equipment. It has NO connections whatsoever to the transmission wiring! The two pins you circled in white(P and...

The driveshafts are pretty steep on the low pinion rigs(~9 deg). The rear DS is also at maximum length(weight/mass) for that type 16 DS, so raising the rear pinion reduces the DS angle and the resultant force from longitudinal vibrations. At highway speed the low pinion driveshafts are way...

Because it was on the pools schedule before it was on the DRMO list:)

The book you want is the MD3070 troubleshooting guide. Google "TS2470EN" and you can find it online for download as a .PDF Like General mentioned a weak connection in the harness could be limiting the current delivered down to that C7 solenoid. pulls in with the peak signal but relaxes...

Sounds like you are following the right path. Be carefull energizing the trans solenoid coils. They use low impedance coils(3 ohm) so they can responde faster, but you must use pulse width modulation signal as direct DC(100% duty cycle) will feed them too much current and cook them… The...

OK, if you are in drive, when you select mode does the display change from 2-7 to 2-5(range pre-select)? like I described above when you select mode the only thing the transmission does is limit your gear range to 5th gear. when it does this, it outputs a mode indicator signal(path to ground)...

What truck are you talking about(year and model)?

Cleaning all the connections at the PPD usually fixes the issue…. Very common problem! Yea I regret teaching the wife to use the Backhoe…

Ok voltage dropping off when load is applied is a classic symptom of a high resistance connection. That or a really bad battery. easy enough to track down though: Since you say you have lights, which are all 12v, i suspect the ground to 12v batt is OK with the switch turned on/load applied...

1. K02 in the power panel goes click when you turn on the IGN switch(one hand on the relay, other hand on the ign sw), but no idiot panel lights in the dash? 2. Does anything else work when you turn on the ign sw? Relay K02 energizing should power wipers, horn, heater blower, transmission...

Well it doing a power on self test is a great sign. But until you can read its codes, it is grasping at straws. Could be something as simple(and quite common) as a wheel sensor having intermittent connection or detection(sensor backed out from tone wheel)…

I believe so. They replaced the original spec roller thrust-bearing with a different roller thrust-bearing, then they replaced that second bearing with the current spec thrust washer...

Well I needed the room for my habitat, so the cooling system and oil fills were getting re-engineered anyway. I actually wound up fabbing my own front wall truss that bolts in the same location, only down at the floor level, arching close over the top of the transmission. I even re-used the...

I actually came across a video of a manual one a while back but cannot locate it. If you could machine a cup to hold one with a gallery to supply fuel to the ports, and position the rack with a vernier caliper, you could probably use an Arbor press to cycle the injector manually. Haven't come...

Cool! Based on the way they did the ground connections from the factory, I am really amazed we don’t have more issues like this than we do…

Here are some 3116 injector test videos… Think this one is out of Albania:) This one is out of Asia?

exactly, its by S/N, which can be located on the right side of the transmission housing, metal plate riveted to the aluminum case.

You need to look thru the tech note bulletins(i think they are in this discussion), and compare the transmission S/N cutoff where they switched to the current bushing from the previous specced needle bearing packages. Compare that S/N to your transmission S/N to see if yours was produced before...

Yea a little smoke when cold is perfectly normal on a 3116…:)

I don’t see it really supporting the frame all that muck as it is narrow and mounted perpendicular to it. Because the engine and trans is located there, trucks don’t typically have any re-enforcement there. Looking at it as a whole, it probably weakens more than it would support as they had to...
