I thought I would follow up on what action I finally took relating to this thread as well as the much longer one titled "1990 Q45 - Transmission mission".
I ended up shipping my Q45 to Jerry Tucker at All Import Service in San Diego. Jerry was great to work with! The work ended up costing about $500 less than we had estimated it would over the phone. I've got a "new" transmission, cam guides, radiator, transmission cooler, water pump, steering rack boots, etc.. The report back was that I've got a very nice car that's in great shape and was worth putting the money into.
And talk about good service... last weekend Jerry drove my car back to me!!!

9 hours or so from San Diego to the San Francisco area. His wife followed him in another car. They dropped my car off. spent the afternoon in San Francisco, headed south for an hour and spent the night in a hotel near some friends. I paid him for the gasoline for both cars and a night in the hotel. Saved me hundreds from having it shipped home. He said they felt like taking a road trip!
So I've got my car back and it's working great. I want to thank all those who gave me their input along the way. This board and the other Yahoo owners club are great! I'm a happy guy. And once again, THANKS Jerry!! I wish you had a shop a little closer but I would work with you again in a minute if the need arose!
