 I bought this car used from a local dealership.I have found the gas mileage to be great but the transmission has a mind of its own at lower speed and sometimes while slowing down to a stop it clunks into a lower gear.Its disturbing and annoying (almost scares me) when it does this.Sometimes when I put it in gear (mostly in reverse it hesitates and then goes in gear suddenly.I have to make sure I always have me foot firmly pressed so it doesn't lurch forward or backwards suddenly.I don't know if this is normal for all Jettas this year or not but it makes me think that I could have transmission problems down the road?!It does have plenty of pickup when I put it in "sport mode"
