Here's how I understand the shift tables...
The 4 buttons (tables) control shift points by %tps and mph. This allows control of both part throttle and WOT shifts. For the upshifts, this is the mph where the shift occurs. For the downshifts, this is the maximum speed at which the downshift is allowed.
On the main shift tab, I leave the upshift mph low (stock), change the downshift mph to the same as the tables, and change the upshift RPMs. I was thinking the same as Flyer - the main tab is max/min values at WOT.

On parish8's down/up shift issue... I have noticed that my 1-2 shift can occur at different-than-expected mph/rpm after a hard downshift, sometimes under/over-revving by more than 100rpms. But, going from a stop with no 1-2 shift at WOT is harder to figure out. How far (mph/rpm) past the shift did you go?
2 suggestions:
1) maybe lower your shift rpm/mph a bit while testing this so you don't hit 7K again... ,
2) try setting the shift mph on the front tab a few mph lower than you want it to shift.
good luck

 

uuuhhhhhh OK?
I guess it's just easier if I can actually see what you all are referring to.

In my head you are referring to the 4 tabs on the right and the main window when you open up the transmission tab?
all 3 columns have to match what you have done in the tabs correct?
or do you leave these alone. I thought I was understanding this better but now I am confused again

 

I called the 4 tables Buttons (Norm, Hot, Perf, and Cruise). Parish8 is calling the 3 main tab columns the "front" tab.

I have seen people who say they only change the 3 main tab columns. I have also seen people who work mainly in the 4 "button" tables. I do not think it is necessary to have the 3 columns match the 4 tables. It is still not perfectly clear when the PCM decides to use which tables, as evidenced by parish8's unusual shifting results...
hope this helps

 

01 Thunder, as far as your original question, I agree with parish. Most of the part-throttle shift tuning is based on your personal preference. I smoothed out my factory shift curves a little bit, but not as much a parish did.

 

sorry for the confusion i haven't been very clear.

i first adjusted the "normal" tab, it helped alot but i had that funny shifting at 40-55 when going to wot.

then i put the "perf" and "hot" to the same numbers as well as the numbers on the main tab, this caused it to not shift at all when i was at wot but it did give me the shift down at 50mph and hold it there, just wouldn't shift.

next i put the main tab numbers back to stock, this put me back to where i was before with the funny down shift and up shift.

i think just modifying the "normal" tab might be the way to go and then mess with the numbers on the main tab but not go as drastic as i did before and see if i can get it to do what i want.

 

ok then that makes since.
that is what I have done,I made my shift curve as smooth as parish8's.
havnt up loaded it to the truck yet, because I have worked 26 hours in the last 36.
but I will and will see if it helps.
the only problem Im having right now is the down shift from 4th to 3rd. it's set to low.
wont shift out of 4th if im going faster than 80mph
maybe this will fix it
Thanks guys

 

01 Thunder,
Know what you're saying about the 4-3 shift... I have done that myself. I just adjusted the normal shift table and the 4-3 on the norm column of the main tab to correct that kind of thing...

 

so on the normal tab where there are the cells. do you adujust at 0% or 100% to help it down shift correctly?
also I'm alittle leary about messing with the main tab, i'vealways heard you have to have things just right or it screws it up?

 

if you just want to adjust the WOT shift points all you have to do is adjust the rpm's on the main tab.

goto the normal shift tab if you want to adjust your part throttle shifts, you need to adjust whatever part of the shifting you are unhappy with, i did most of the table and like it alot better but it still needs some work. i was driving into a 30+mph head wind today and it was on the verge of downshifting all the time.

 

sorry if I am sounded like a broken record, but I have it narrowed down to that I need to change the main tab for my down shifts, and yes parish it is at WOT that I am unhappy with the kick downfrom 4.
so how close do the up shift and down shift need to be. my rev limiter is set at 5700 for my 3-4 shift
although I do like the fact that I no longer need to have the throttle down 3/4 of the way to get it out of 4. Got it to be about alittle over a 1/4 and it will get out of 4th and into 3rd. so I am getting somewhere with it
