68 with auto clunks shifting into drive or reverse
I searched through all 27 pages in the transmission and differential discussion section and did an advanced search but could not find an answer to my question, so I am posting here hoping someone has the answer.
I am the new owner of a 68 convertible with an automatic transmission and the Hurst His/hers shift. When I shift into either drive or reverse, I get a clunk and the car jerks (forward or reverse depended on what I am shifting to). The idle speed does not seem excessive because when I am at a stop light with one foot on the brakes the engine sounds right (sounds like if it were much lower rpm, it might stall). Can anyone shed some light on this problem (what is causing the clunk and what can I do to eliminate or at least decrease it)?
