I have a '69 400 with TH400. I just had the Trans-go shift kit installed when my car was in the shop getting the heads ported.
I got it back two days ago and it doesn't seem to be kicking down when it is supposed to. It will kick down at odd times during acceleration but not when floor it.
Before it went to the shop it seemed to kick down correctly.
How does the kick down system work for my car and what should I be paying attention to to get it working correctly?
