occassionally while slowing from 15 miles per hour to 5 miles per hour, i’ll hear a vibrating sound coming out of the engine area like a gear trying to catch and then when i slow to 5 miles per hour, i hear a snap like it just caught or snapped into place and fixed itself. The car drives fine while this is happening, and at all other times. I have 125K miles on it and it has been well maintained. Originally i thought the sound was coming from the front right tire area and had the brakes and shocks/struts checked… The sound could be more centrally located though. What is that?
Hard to say, but if it is the torque converter not releasing properly that is a significant problem. This issue needs attention to be sure you don’t have a major problem.
