In thinking about it further, I may just be doing the press-and-release interpretation because old '70s carbureted engines needed that press-and-release to reset the choke before starting. Obviously that doesn't apply the same here.

I interpret it as push it and release it, then start. But that's why I included the references in parentheses, in case you want to read it yourself. That procedure I wrote in created by stitching together several different parts of the puzzle, from different places... otherwise it's hard to...

I finally had a chance to use the above procedure to recalibrate the throttle position sensor and transmission. It worked like magic. The transmission shifts really well now, up and down. It even stays in 3rd until the truck has come to a complete stop for 1-2 seconds, which is nice because...

WTEC II/III Transmission and Throttle Position Sensor Calibration: WTEC II TEPSS requires calibration after replacement. Procedure found in TM 20-3, page 8-5 (p 637). Procedure for WTEC III is similar, and is in the manual on page 8-7 (p 639) immediately following the WTEC II procedure. The...

Thanks, I'll check for it. What's your thinking here? I have my foot off the gas to slow down, the TPS can't tell that, and so it downshifts early while it's still at too high a speed (and then the RPM jump up)? If it could tell it would know to wait longer?

No, no codes. And I followed the throttle adjustment procedure in TM, I'm not sure if that covers the throttle position sensor adjustment too. The procedure had me loosen the throttle until it contacted one stop, then floor the pedal and adjust it until it touched the other stop.

Before the engine swap, it seemed to shift at appropriate speeds. It would shift up into 7th gear by maybe 40-45MPH (in 7th while driving around town), then down at a lower speed that felt ok (maybe 35-40MPH?). I don't really know what it was doing, because it wasn't noteworthy. I just know that...

Because I don't have a tach, and the truck isn't working correctly. I swapped engines, and during the swap we broke the engine speed sensor. Now the truck shifts way harder, especially down, than it used to. So I'm actually trying to figure out what's wrong, and it seems like a good...

I was doing this by myself, so I had to start the engine to measure. I had installed it to 2 turns back from bottomed out in contact, as the TM said. I was reading 0.025VAC, with the engine running. I turned it in to about 5/8 turn backed out, and am now reading 0.260VAC with the engine...

Just another 3116. It happens to be a 290HP out of an MTV, but that wasn't really intentional.

I called the Cat dealership, and it's not an engine part. Does anyone know anything about it that might help me track one down (military or civilian part? part number? etc.)? I'm trying to get this engine swap done to be in the parade on the 4th, so I need to move quickly.

On the Cat 3116, there is an engine speed sensor (part 4) screwed into the driver's side of the bell housing (TM 9-2320-365-20-3, 7-38, Page 406). Two questions... 1.) Are replacements available? Is it a military or civilian part? 2.) What does it do? Is it only used for a tachometer...
