I recently had to replace the top tranny bolts because the person that rebuilt my tranny for the p/o put the wrong size bolts in and they weren't seating, causing pretty obnoxious vibrations. Getting to the top bolts isn't that hard. Just get a helper and be creative with several feet of extensions. Pulling the motor, however, also isn't too bad.
