need opinions...

i posted about a week ago about my transmission slipping very very rarely, but slipping none the less. i discovered yesterday that when the car hits a big bump, or if there is a lot of weight in the car, it slips. yesterday i hit a very large bump and it slipped for about 5-10 seconds and then caught and ran fine after that. i have had my car looked at (brakes, etc.) and the guy that looked at it and said i have a transmission leak, but not fluid. does this mean that when i hit a bump or have extra weight in the car it causes the engine and tranny to momentarily disconnect? please any imput will help i am slowly narrowing down possibilities.

Maybe the torque converter is bad
