46RE lockup tables

[beargibson3100]

Is it possible to adjust the TCC timing tables? I've gone through the transmission, rebuilt the valvebody and still it the 3rd gear (towing mode) lockup is delayed till 60. It use to be 40. I have all new quality sensors, upgraded pressure sensor (borg warner) ttfre pro shift kit installed. Low stall built converter. After it locks at 60, it will then lock at the 40+ schedule until you drive slower than 40. I'm baffled by this. In standard drive mode it locks normally at 45.

Could you share the tune?
Do you have any log?

[beargibson3100]

It won't let me share the tune from my phone. But I have had the tune from Henifever on there since 2019. Then I broke the one way stator bearing in the converter in 2021. Ever since then 3rd lockup has been delayed. This year I bought the mpvi3 to figure this out, but I don't see a timing table for lockup in 3rd gear. It does show lockup speed, but it has a lower number that cannot be speed, maybe TPS voltage, but thats what I'm trying to figure out. I'll try to share it tonight after I get home.

Output Shaft RPM?

Here is the current tune I'm running.

The apply timing for lock-up is strictly based on TPS , bake switch and VSS signal. Governor pressure and OSS signal has nothing to do with it. Without a log it is impossible to help you figure out which input is causing the computer to command it that way.

What parameters do we need I'm not yet sure what trans sensors I can log on the 46re. I haven't set it up to log yet. What I find odd is that it acts normal when in OD. Heck with the v/b reprogramming kit it locked in 2nd when I was traveling slow enough it wouldn't shift to 3rd.

what you need has nothing to do with what is avail

least that is how it is for my '99 dakota

here is the channel list for it:

these are all the channels it will populate:

and a log:

these jtec 5.9's LOVE corn tho

love it like a fat kid loves cake

Hopefully VCM Scanner is able to pull more parameters than what LilSick has in the log of his Dakota because that's totally useless. You want to have the VSS, brake switch, TCC command, engine RPM and TPS at a minimum. If you can't get that, then you would need a different scanner that can do the job.

Robert, I think I emailed you a few weeks ago about Stacking my separator plates in the wrong order and cracking my drum.

Here is a long log file from today,I have a lot of data there. Near the end I turned tow haul mode on (closed) and initially locked it at 60. then as I slowed I was able to lock it several times down to 40. Then at 40 I gave it enough throttle to kick it down, but you can see after kicking it down and out of lockup it won't re-lock . Only thing I can find odd is that it shows the shift light on until the tcc is commanded on, then it shows the light off. Which is really odd since the shift light is turned off in the tune. I hope y'all can see something I'm missing.

Yup, that was me you emailed about the no reverse and then we found your direct drum was cracked open because the separator plate stacked up was inverted. Everything looks right in there TPS, VSS and brake switch wise, it has something to do with that "shift light" thing it seems as everytime that PID goes to ON the lock-up gets commanded and everytime it goes to OFF it commands it to unlock. I have never heard of this shift light parameter until now, I have no idea what that is. The only "shift light" thing I have ever heard about is on stick shifts where some vehicle will have a light telling you to upshift but it should not apply here on an automatic. So it must be something not set right on the tuning side of things, hopefully someone that knows more about tuning than me can help. I know just enough about the tuning side of things to be dangerous.

I believe the software is the same between manuals and auto's they just change the settings. My 04 wrangler shows the same transmission parameters it just has them disabled. I guess I will pull the tune to confirm it's off.

Yeah check that, and also be sure to share your tune here if you haven't already, cuz otherwise nobody can really help that knows about tuning. I personally only care about logs because all I know is the transmission side of things but for most other people on here it is the opposite.
