Anyone fooled with this?

Jeff answers:
Here's my method:
I first adjust the linkage under fuel pedal above spare tire, then fine tune
at throttle body - prolly where you need to be.
Take-up slack if upshift is low rpm or too soon, increase slack if upshift
is high rpm or too late.
At the throttle body end, don't lose the spring retainer that holds the
spring on the linkage to the throttle body when you turn the linkage to
adjust.  The spring tension is what moves the throttle body, not the
adjustment so throttle response should not be affected.  On my '89's, the
upshift drops the rpm's 800-1300 depending on the rpm range.  I adjust so
the upshift occurs no later than 4600 rpm WOT. (digiwife)
Works for me.

Good luck,
