None. I've never had any problems with either of my SRT-4s. I don't know why people complain about the trans. Mine shifts well. Then again, I'm a 32 year old adult that drives this back and forth to work. So I'm not powershifting and hitting the BOV every chance I get like the rest of my neon brethren lol. Car has zero issues that I am aware of. Be more than happy to take anyone for a ride that is in my area. The car sits all day.
