I've got to ask @Dynamic what has to happen for the transmission to downshift out of overdrive to 3rd gear? 


I'm wanting the truck to hold road speed with the cruise control (vacuum cruise) and it will hit a hill or grade and the speed fades way back like -10 MPH from set speed then it downshifts and struggles to make up the lost speed as it climbs. 


Now the TV cable if I add a bit of pull to the TV cable it makes the shift rather overly firm (bang). A neutral position is a good firm shift. Slight bit of slack shifts mellows out a bit more. This doesn't seem to make any impact on the downshift while in cruise. 


This leads to the fact the cruise module might not be pulling enough to get a downshift or what? That why I want to ask the transmission guru! :)

I know with my truck, if I’m cruising along in 4th locked, it takes almost %100 throttle to get it to drop into 3rd locked. Might be the same with the 96 but not shred just figured I’d chime in with my experience.

Like I've posted in my Back to Spark Plug thread I'm going to change up the tires from 235/85 R16 to 245/75 R16 to aid in the low-end response. This size change will add 26 revs per mile more and the tire is about 1 inch smaller. Then the face will be 10mm wider. Should give me a nice boost to the gear ratio.
