Powerglide shifting problem, vacuum ?

So here's the problem in my 63 wagon {350/powerglide}, when the modulator line is hooked up I have no up shift, When its disconnected it will up shift then slip at full throttle, Idk its driving me crazy I changed the filter and modulator and its doing the same thing. I have the modulator line hooked to the back of the intake is there to much vacuum? , mind you this is my first powerglide

Do you have the throttle linkage from the power glide to the carb hooked up?

The vacuum on a glide only controls internal pressure, not shift timing.

Is this glide a recent rebuild or an old unit ?
Dont worry how old you are... it is the mileage on your body that adds up.

The linkage is hook to the carb, the powerglide is an old unit it ran fine with my L6, I don't have the kickdown hooked up I just recently found the V8 linkage would this affect shift points? I do plan on going with a th350 when i get some extra cash you know how it is when you have a couple classics , Maybe my glide ready to take a dirt nap or is there still hope for it?
