1997 Chevy Lumina 3.1 mileage: 73,000. Very hard shift (bangs) from 1st to 2nd after driven 40+ miles. I had the trans serviced at about 68K and asked the mechanic to clean the accumulator. (He said the trans was dirty but no other problems.) This did not remedy the problem at all.

The problem with your transmission is probably due to the fluid pressure control solenoid in the valve body. Replacing it and clearing the codes in the drive train control module should solve the problem.
