Still battling this shifting matter...

[Christine in FL]

1996 E320 with 722.329 transmission. The original transmission completely bit the dust shortly after we bought the car so I purchased a used unit from a lower mileage crash victim. After the swap, the replacement transmission hasn't wanted to upshift until at least 3,000-3,500 rpm. I have taken the following steps to troubleshoot this issue:

1. Adjusted the bowden cable and even disconnected it completely at one point. - No change, still wouldn't shift.

2. Checked the kickdown solenoid and disconnected it also. - Still no change, won't shift.

3. Discovered and corrected a vacuum leak - Still no change, won't shift.

4. Checked the working pressure and modulation pressure. Both were in spec. I'm going to check the governor pressure tomorrow.

5. Removed and rebuilt the valve body from the other transmission and swapped them out. - Still no change, won't shift.

I suppose my next step is to remove and inspect the centrifugal governor assembly. That is on tomorrow's agenda also.

Question: I have read that the governor assembly is serviceable while the transmission is still in the vehicle. From what I experienced while replacing the transmission, it is VERY tight up in there. Is there some special technique to remove it that will make things easier for me?

Any and all suggestions are greatly appreciated!
