4L80E shifting issue
Problem is when I spin the tires off the line and get out of the gas it shifts to 2nd, then when I get back into the gas it kicks down to 1st, but then the trans never gets a command to shift back to second. The log shows that 2nd gear was not commanded to shift until after I got out of the gas bouncing rev limiter.
On a good run with no spinning, the trans is shifting fine.
Can anyone see what is going on with this setup? I am stumped....
Thanks.
