Looking for help for a 700r4 tp 4l60e swap using 0411 pcm

[MikaelT]

3.42 and 215/70 r15 (26.85 inch.) but yeah I will need some fine tuning, its shifting a bit too fast at low throttle, and I know very litle about tcc lock and all that stuf so I need to comfirm that it is working as it should.

looks like 12202088 OS

I think I went with a base calibration from a 2001 s-10 2wd wich seemed closer to my astro's spec than a 4x4 blazer.

215/70-15

751.13 revs per mile

751.13 * 3.42 gear ratio
=2568.8646 trans revolutions per mile

2568.8646 * 40 pules per rev =
102754.584 vss pulses per mile.

Change HO104 TOS Revolutions per mile to 2568.87
And HO101 VSS pulse per mile to 102754

And that should get things shifting at the MPH you tell it to.

what does 'ho104 tos' stand for ? I found the pulse per miles setting but not the other one

That's how it's labeled in the xdf I have. It's transmission revolutions per mile

TOS is trans output shaft

got it, I was using universal patcher thats why ! ill look into those table in the morning, definatly a lot of data to digest. Realy apreciate you helping me out. Just blew my 350 on my k2500 and getting this van running was my only option to have something running again. tyvm

That sucks about the 350.
Universal Patcher is an awesome tool.
I can't remember how it's labeled in UP, but I believe it's under speedometer.

The shift tables if I remember correctly are labeled 1-2 line 2-3 line, and so on. Under transmission category.

I had tunerpro installed as well, I went ahead and downloaded the xdf package and found the tab exactly as you labled them.

Here you can see up shift to 4th is commanded before lk in 3rd.
4th is set to lk at 46 mph
and 2nd lk is dissabled

Here is a copy of my spreadsheet I use to aid in shift schedules.

I already put in your stock tcc and shift tables for normal mode

It should help you visualize the changes you make and how it affects other parameters with the graphs.
