You da man!

I checked it with the strobe I have. Matches up at 1500 and 2000. When doing a pedal to the floor accel on flat road, it revs to 2400 before shifting to 3, then 2100 before shifting to 4. based on the feedback and also the Allison "tips" manual, I'm wondering if it's worth...

I'm looking 👍

Can they be setup as a continuous monitor, while driving?

So where can I download the CAT ET software so as to read the rpm? I assume I'll need a serial to canon cable to interface to the truck. Seems like everything needs it now, even my golf carts connect to my laptop.

Could this happen if the internal speed sensor on either the input or output is flaky? The strange shifting issues I had previously went away the moment I redid those chassis grounds. But I'm wondering if those intermittent overvoltages from the bad alt damaged sensors in the trans? Leading to...

It's running off the pulses from the new delco alt. The "R" terminal. Shows 700 at idle and 1350 at high idle. I've driven it around, seems to be accurate based on driving results. Showing up shifts at ~1800, down shifts at 1100-1200ish. maybe I should get that ET software. I have an old...

Did it peak well above 1750 then come down, or just go there and stop? Mine went up to 2100 then I backed off bc I was unsure of going too high.

No I checked the video bc I was in front of the security camera lol. It was trying to push thru the breaks. I could hear it. Front flexes/lifts a little. I do the rapid warm up procedure a lot in winter so the response is within expectations but I only go lite throttle when I do that. Is it...

Would the Clutch codes only show up during power on? I checked today and the Wtec shows no stored codes. All registers are "-". I previously deleted all stored codes months ago after the starter/overvoltage debacle. So there's been no stored codes since then.

I'll have to check tomorrow. I never owned a vehicle that didn't blow a trans during my ownership. So this would be par. Backhoe's at 6000 hrs and that trans is starting to go. Track loader is immune since it doesn't have one. Items 3 and 4 above don't make sense since the truck drives fine...

Did you break my transmission!? 😂jk

The Allison mechanics' tips manual says https://www.manualslib.com/manual/2494681/Allison-Transmission-3000.html

Hmmm. I tried this on the back drive to my barn which is 7-8 degrees, with the brake held, at temp. Rpm did not "stall", kept going up to 2100+ and I backed off throttle. Truck was flexing, trying to go. Only a couple seconds elapsed. What does this mean?
