Strange Transmission Shifts

[rrgrassi]

Here's one for the tranny guru's....

When cold, tranny hits all the gears fine.

When at operating temp, 1-2 is good. 2-3 feels like it is either hunting, double shifting, or going from 2-4, back down to 3. 3 to 4 is good.

Keeping the selector in S does not change the behavior.

The 3-2 valves have been removed, and the EGR disabled. It loes have lock and HVAC vacuum issues, but those have been disconnected and plugged. The car has no problem shutting down.

The tranny was rebuilt or replaced by the PO at 185,000. It is due for a fluid/filter change. Fluid is bright red, and does not smell burnt. It does feel like the selector bushings are getting weak as well.

Thanks!
