How do I calculate tq converter slip?

[danl]

I know all the numbers to enter on this page:
Racing Calculators - TCI® Auto

Except the rear end ratio. There is another reduction done inside the trans after the planetary and before the final drive. I think this is what is messing me up. If you put just the final drive in you get some really bad slip number, like 36%. I know the real number is in the mid 4's for "true" "rear end" ratio.

What is this number!!!!!

You mean auto drag on the drivetrain vs power? I'm having a hard time comprehending what your saying jack.

The Kiggly mod does have full line pressure right?

I want to know what number to put in for rear end ratio.

Does this chart help? Tranny gear ratios for DSMs

 

[Auto RS T]

3.545- Manual Trans
3.307- Auto Trans

I also see it there on My1glaser's chart.

I could never get a definite answer to this...i've just been comparing rpm/trap speed/tire size between converters to figure out what ball park efficiency should be in. I know the final drive of the trans and rear end ratio but haven't been able to get the right final figure. I hope you figure it out...
