I am attempting move an 01 Saab 9-3 automatic that was been slipping intermittently before it was parked about a year ago. The last straw last year was when it started slipping on the highway (smoke, high RPMs), and was towed to it's current location. I'd like to bring it home (50 miles) to replace the transmission. I was able to charge it up and start it recently, and it seemed to drive around the driveway and parking lot just fine. The fluid doesn't appear to be low, and surprisingly isn't too burnt. My theory is that the screen inside is being plugged up after some amount of driving, and the transmission is loosing line pressure. Does anyone have any recommendation for additives I can dump into this thing to help limp it along for another day? I'm not really concerned about long term longevity here - just trying to avoid paying for another tow. I've got all day, so I can take it slow, take brakes, etc. Thanks!
