Prove you are human: How many forward gears does a 4L60E transmission have?

This happens in other tables as well, depending on year/platform.

In da picture...

So if 0->1 is "44" (whatever that means, for now), then at 43/199.4F it will be still off, at 45/203.0F it will be on, and the actual switchpoint will be somewhere...

Seems like it would also be pretty easy to test yourself, by logging all the related stuff.

You can't write the truck's stock file back to it if the only file you have is one that was made after the old trans was gone. You'd need to have read it out while the old trans was still in it.

These look... similar. But different enough to maybe make a difference. The EGR valves look identical but are different part numbers, I don't know what is different between...

If O2s or injectors are swapped bank-to-bank it creates a feedback loop. As long as everything is good, everything is good. But if either side starts to go away from zero then it just keeps going...

The file you've already read out of it is everything that will ever come out, that is 'your file'.

CTRL+L, find one from before you made the change, right-click & Open in New Editor and save.

What I mean is, what file would you write to it other than the one you already have?

Nuh uh.

Code is not in the manual for 2002 Astro.

There are two TP sensors and two (sometimes three) pedal sensors. The multiple sensors have different voltage ranges and sometimes sweep directions so they can be used as rationality checks for the...

The info in the logs (can't see the tune file, because it wasn't posted) shows as 2004 Sierra LM7. Application matters on these things. I mean, if you want the stuff to work like it's supposed to.

Looking at the third log, if you have new upstream O2s why do you have pending heater circuit codes for both banks? P0135 & P0155. Did you use sensors looked up for whatever the year/make/model the...

Do you not already have a file, and have it licensed? Never read/written to the truck before this?

Also would be much easier to make sense of if you made a log showing JUST starting from a dead stop, accelerating at constant throttle, and letting the trans shift. There's tons of distracting shit...

If the TCM in the reman unit is new-new and has never had any code in it of any kind, HPT will not recognize it. It's got to have a bootloader present or something like that. If the TCM has that...

Pressure Delta between 58 PSIG (400 kPa gauge) in the rail and 14.7 PSIA (100 kPa absolute) is 400 kPa. The Delta isn't either absolute or gauge, it's just a differential pressure.

It's real common for there to be something wrong that doesn't set a Pending or Current code, but still makes it default to max retard in PE. The sensors will still work detecting knock and pulling...

Do you have an AIR pump, and do you want the PCM to think it's available anytime coolant temp is above 36F? If you do have an AIR injection system (I don't think you do) is an '02 Express PCM going...

Type CTRL+N. Type in 'air' (or any other keyword).
