I agree with nodd89. Here's something from another PT forum..........

There is a Technical Service Bulletin out, TSB 18-007-01, that I read about that may help with the automatic shifting problem you are bringing up. From a previous post:

"The bulletin effects Pt Cruisers with automatics built before 02-08-01. The fix is a software update to improve the feel of a 2-1 coast down bump and a better passing gear response from 3-1 or 2-1. The update is supposed to provide a smoother crisper shift and get rid of the coast down bump. The soft ware will make lock-up of the torque converter
less sensitive to throttle changes while on the highway. Recommend if you want the up date complain of a firm down shift when coasting to a stop sometimes."
