PDK Hard Downshift 3-2-1

Recommended Posts

Hey folks, just sold my 2003 Boxster S Tip 4 weeks ago and was excited to pick up a 2010 CPO Boxster S PDK w/Chrono two weeks ago. Flew from Seattle to Louisville for a quick 2400 mile road trip home. The bad, as soon as I drove it off the lot it was shifting extremely hard (thunks) in lower gears 3-2-1 in both sport and non-sport mode, but it did fine in upper gears on the freeway home. Once home it continued to get worse so I took it into the dealership and they downloaded a software update (TSB# 35/09 ENU 3730) after I had to convince them it was not just because I was newbie to PDK. It was better but still pretty rough. Oddly enough when in sport/manual, the downshift was very smooth. They said it would take a couple hundred miles to adjust and after 350 miles it suddenly got much smoother the last couple of days. I also have some of hesitation in 1st gear noted on other post. So the question, is this normal operation for the PDK and would I expect it to keep getting better?

btw: I've done a lot of research on other boards and have found others with similar PDK issues, but no clear resolutions.

Update: After another week and a few hundred miles more, downshifting has continued to get better in all modes, so it looks like the TSB update did the trick! Still has the slight delay from dead stop though, but it appears this has been a long standing issue without resolution, even on 981s.
