Oldsmobile/Buick Repair: 93 Buick LeSabre, buick le sabre, buick lesabre

Question
Hi, just a little back ground on the problem. (93 Buick Le Sabre) About a month ago we noticed a leak from the front-end passenger side of the car, it was transmission fluid.  What had happened our transmission fluid was leaking in the radiator and into the overflow tank.  We had the radiator replaced and all seemed to be well.  Now I have noticed a leak again in a similar spot, as well when shifting from park into drive, the car seems to stick in neutral, after shifting again from park to drive it will go into gear and drive.  Are you able to tell me what the problem might be?  Our mechanic said that all connections are tight from the radiator, he cannot find the source of the leak.  Thank you!
