View Full Version : Transmission clunks

I have a 1994 Prostar 195 with a LT1 engine and a std 1:1 ratio trans. When I shift into gear it has a small clunking sound. My neighbor has a 1993 205 Prostar and his trans is very quite when shifted. Is this something to worry about?

Clunking sound is not good. If the tranny shifts at the proper RPM (meaning it doesn't increase RPM's before shifting causing the clunk) then there is the possibility of damper plate or something amuck in the tranny. If it is increasing RPMs then shifting causing a clunk it is just a throttle cable or linkage ajdustment.
