1974 454 automatic transmission seems to slip "P" park

by AL PITT

Let me first say thank you for having a web site for novice mechanics. My soon to be 1974 convertible with 454 automatic seems to have a very small sweet spot to maintain a parked position. I do not know if this is a big issue. It shifts all gears well and reverse. No gear slipping when shifting or smoke. I am afraid she will roll away on me. Any thoughts are appreciated. The car sat for 5 years due to owner illness. 90,000 miles and runs strong. Need to know what I am getting into. This is my second C3.
