I have a 1998 Chevy Silverado. 305, it is slow to go into gear (drive or reverse) from park when not warmed up. Seems to have a slight bit of "surging" until it gets well warmed up. Once warmed up (10-15 minutes) it seems to be OK.
Except, If I have to stop quickly, it bangs into gear if I put my foot back on the gas pedal to accelerate again right away. If wait a few seconds it does not bang into gear..
It has 428000 kilometers on it, fluid is clean, full and no burnt smell.
Has never towed a trailer to my knowledge. I have owned it for over 200000 of the 428000 kilometers.
I love the truck, it rides so nice.
Any ideas?

You've got alot of miles on it. Might be time for an overhaul.
