Need help on downshifting issue.

[stroker97k1500]

have attached my current tune below.
I am currently trying to figure out how to make my transmission down shift from 3rd to->2nd from 55mph to 78mph over 65% tps. I have tried changing the throttle kickdown table. I haven't messed with the down shift part throttle table as of yet as I didn't know how that would affect it. I wanted to get some advice first as what I was doing wrong, or where I needed to be looking.
Thanks for any help!

IIRC, throttle kickdown is pretty much for WOT. The part throttle tables are where you need to make your changes.

The way I usually read the downshift tables is:
Assume the value of the 50% tps cell is 30mph. So, when you're going 30mph, you will have to apply 50+% throttle to get the trans to downshift.

If you're going to be changing the trans tables, check the spreadsheet I made in the trans forum. It'll help you prevent crossing the upshifts/downshifts and torque converter tables.

Thank you for sharing that! It makes a lot of sense now

Remember these 2 things:
- upshift tables: operating point must cross to above the curve to trigger upshift;
- downshift tables: operating point must cross to below the curve to trigger downshift;

It doesn't matter if the operating point moves vertically or horizintally.

I moved this to the trans section.
