Ok everyone, sorry for going dark but got distracted by work and other things. Got a chance to go through the troubleshooting guide and did some other tests. My findings:

1. First, I determined I had a much worse pan leak than I realized. Looks like it was overtightened in the past and each bolt hole was raised way above the mating surface. I found a spare pan and fixed the leak, refilling to verity that I had full fluid. Same issue persisted.

2. Next, did more engine checks, including a compression check (120 across all cylinders). Everything looked fine with engine performance.

3. Finally, went through the road tests in the auto-tranny troubleshooting guide and the car failed the torque converter stall test by more than 600 RPM.

This seems to indicate that the torque converter is bad, according to the troubleshoot guide. IS this a common failure on these transmission? Is there any variation on the torque converters I should know about? Any tricks for installing the converter that perhaps I didn't follow?

Thanks!
Brian
