With a rubber-tipped blow gun you introduce air into the various passages in the case to apply the bands/clutches and listen for big air leaks.
Thanks, John. The kit I used had me install a plug with a smaller hole in it into the front clutch apply passage in the case. Any idea what the purpose of this was?
Not the john you questioned , but that plug is to slow the apply of the front clutch due to the increase in line pressure making it happen faster without it . It would not cause the sluggish feel or cause your soft 1-2 shift.
