Here's what Ross said regarding the adjustment in question:

"Just lengthen the pull rod to the carb a bit until you like the way the trans upshifts. There is a singular lack of rocket science involved. Besides, that is likely all that got changed when the carb was taken off."

Thanks KP, I had seen this post, but didn't fully review the entire conversation. I'll try setting my cross shaft to factory, if it's not already, and see what happens. Does lengthening the rod cause the transmission to shift from low to high sooner or later?

I'm not sure I feel my transmission lock up. Is it as noticeable as the shift from low to high? Maybe it is happening so close to the shift to high that I'm not noticing?


I have a non-Gear Start transmission, so I only have Low and High gears. Transitioning from Low to High while moving is not recommended. I tried it once....scared the crap out of me. High gear has two "gears": first is using the torque converter, and second is the torque converter locked into direct drive. The transition should happen around 35 mph on heavy throttle (if I remember right). Mine is a bit later than that so I need to adjust it. My transition is noticeable. It's not a hard clunk but you can definitely tell when it shifts. My brother-in-law's car is set a bit too far in the opposite direction where the direct drive kicks in very early. His is less noticeable because of that.
