I have a 1994 Mazda B2300 with a manual transmission. The transmission performs great...its a little jerky, but I believe that is just the way the truck drives. It never slips or won't go into gear...basically the transmission works great. My problem is when going down the road when I let off the gas the car the transmission makes a clanking sound when the gear grabs. If i ease off the gas it lessens/prevents the noise all together or if I press the clutch in then let it out in the same gear it doesn't make that clanking sound either. I'm looking to sell the truck and would like to know what to tell people is wrong or if its an easy fix I would like to fix it myself. Any advice?
