I have a 2007 volvo S40 T5 AWD with 25,000 miles. When driving at slower speeds and I let off the gas, I hear a “clunking” noise similar to driving over a lose manhole cover. The car makes a very slight jerk as well. I notice this as well between 2nd and 3rd gear, but not just then. I am thinking transmission problem, but don’t know and want some info before heading to the dealer. ideas? Thanks.

Unless its under warranty you don’t need to take it to a dealer unless you have one that you trust. The first thing I would check is the engine & transmission mounts. Any decent mechanic can do that.
