Transmission Shudder 700

Hi, I need your help.

Whenever the a/c on, My tranny(AW71) shudder when shifting. First I thought if I do tranny flushing and change the oil, the shudder will be gone. So i did it. The result is the shifting is smooth and no shuddering with the a/c off but, it's still shuddering when the a/c is on. I wonder if there is a correlation between bad a/c compressor and tranny cause, I know my a/c comp. is bad (i'm going to replace it). So please give me your advise.
BTW, I use Pennzoil Dexron III to flush and replace the old oil.

Thanks,

David Hutabarat (91'740TIC)

    I would replace the compressor, since you already know that something is wrong with it. Also replace the engine and transmission mounts, since they are probably allowing the engine to move a lot. The front ones are hydraulic and you get a lot of engine vibration when they go bad. The rear transmission mount tends to separate from oil attacking the rubber.
    That should cure your problem.
