As long as it is not he engine I would not worry too much. Does the car drive smooth ? These transmission are not smooth, they are not quiet and they are well "German" Japanese transmission are very smooth but delicate, the European transmission for the most part are cluncky and strong (I am not including the Panther Tank from WWII in this comment). Make the transmission a winter project, if this is not your daily driver. The way I look at it...my car is not my daily driver, I will do any project on the car, and when I get then I will finish another day, if I get stumped, I will ask for help. I think your mechanic is saying, don't stress out, it is an old car and things will go wrong.
