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

[Fast355]

I'm challenged to understand how a 4.3 V6 TBI Distributor Tach Signal is a substitute for 4.3 V6 CKP signal?

I don't actually know that the '0411 needs a factory CKP signal to operate a 4L60E. I've never tried using an '0411 for stand-alone transmission control.

I've copied / cloned / fabricated the factory way of doing things, and that has worked out for me.

Oddly enough, V6 tach signal is the same as a 3x reluctor and a V8 tach signal is the same as a 4x crank reluctor. There have been guys feeding the HEI tach signal into the OBS Black Box on carbureted L31s for years.

That was my understanding, does this also mean that it would be possible to 0411 swap without a crank reluctor?

I guess it depends what you wanna do, gotta consider all that ckp / cam correlation that vortec engine use.

Trans is unknown, but throwing out every single solenoid and tcc electrical code at once seems odd

Seems to me like solenoids are missing power or ground?
Maybe back probe at the trans connector to verify grounds and power is reaching correct pins?

[MikaelT]

is there a way to to segment swap the trans config from a 1998 bin ? I know there is some on the site but I dont even know if its compatible with tuner pro

[ralmo94]

Segment swaps have to have the same operating system on parameters.

[MikaelT]

it was indeed the pink wiring powering the trans that did not have 12v on it, I supose it take it from somewhere else I didnt power up in the harness, then I got the speed sensor to read something as well and im out of limp mode and actualy shifting gears ! now I cant say if the calibration are good or undrivable but it is a pretty damn good start. I will post my finding soon for the people of the future tyvm for taking the time !

Glad you got it figured out.

What Size tire and Ratio are you running?

Speedo Should be pretty close if you are running 3.42's and 26 inch tires,
If running something else, would be best to have the proper VSS settings, as shifting is scheduled by MPH, not RPM

[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.

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.

just came across this, look like minor difference in 2002 vs 98 4l60e ? could that be an issue ?!
