my 1st to 2nd gear was very rough
then my truck started to run through all the gears by 18 mph 1st to second 10 mph then 2nd to 3rd 18 mph
which way would I turn the screw in the modulator to try and correct the problem?
or should I just get a new modulator?
I believe my vacuum pump works
any input would be appreciated
