Can anyone explain what controls the shift points in the OD transmission of my 4.3L '89 s10? The shifting has become very harsh and at elevated rpm since I replaced a blown head gasket. I freely admit to possibly misconnecting something ... but what would cause the shift points to change dramatically like this?
Finally, can anyone suggest a better shop manual to use with this truck than the Chilton's I have?
Thanks,
Peyton
did you re-connect the throttle cable to the transmission ?
is the bracket holding the upper end in the proper position ?
when disconnected, the little plastic doo-bee-joob that attaches to the throttle body arm should be about 3/8" 'shy' of hooking up............in other words you need to pull the inner cable TOWARD the TB about 3/8 to hook it up
It wasn't disconnected
Aha! You hit the nail squarely on the head! Under the bottom nut on the stud rather than over. Enough to cause problems.
I adjusted this as per the Chilton manual ... causing the harsh shifts. Am now experimenting with the adjustment to find the shift point I like.
Thanks for your help
Peyton
