Built 4l60 slipping on 2-3 shift
Built 4l60 slipping on 2-3 shift I'm having a problem with a build 4l60 slipping on the 2-3 shift only. I have shift time set at 0, line pressure maxed out. It doesn't matter where I set shift points at it will go to shift when I tell it to bounce of the rev limiter then shift into 3rd. It does it on motor 380whp and nitrous 500whp. Its taking .9-1.0 sec to complete the shift.
Any ideas

sounds like the tranny is toast
Set the shift MPH low, shift RPM to 200 RPM below where you want it to shift, then set the rev limiter 200 RPM above that ... if it's still slipping to the rev limiter the clutch packs are toast most likely
Check the trans fluid color and smell, if you have a drain plug, drain a little (just a little) and see if it looks like goldschlauger brand fluid

I had the same issue after installing my new Level II.
I raised the rpm on my fuel cut off and I thought that would work but I overlooked another table for while it was in gear.
That solved my problem.

Call me tomorrow. I'll be happy to discuss it with you.
Send me your .bin files and I'll see if there is something obvious.
Most likely, it is your transmission. The 3/4 clutches are critical to proper WOT shift timing.
