funny shifting on the 727

[gtxrt]

what would cause the tranny to shift at 4500 wot most of the time and won't downshift at a higher rpm but the weird part is every once and a while it would upshift at more of a normal 5200 rpms. tranny was rebuilt and the line pressure was turned up a little. kickdown is adjusted all the way.

You could have some leakage in the governor circuit such as poor ring seal or a mechanical issue with the governor itself.
A pressure test would be in order.

Your tranny probably came out of a big Chrysler that had tall gears. You likely need a governor change. A&A transmissions can set u up. Kim

Differences in the upshift/downshift rpms sounds like leaking/sticking valves in the trans. If the trans fluid is old, try changing the fluid/filter.

 

[gtxrt]

fluid is changed. are saying sticking valves in the valve body ?

 

[Geoff 2]

Yes. Or warped valve body/case allowing leakage.
