986 Tiptronic gearbox - problems with 3rd gear

[NewArt]

It's an odd beast that tip. Mine does what you describe but only in 1st when on starting on a hill. No codes,no leaks, fluid level is fine. I replaced the electric harness inside the pan 2 years ago when I was getting the D-4. Transmission works fine in manual mode flailing through the gears on the track, just that one little gremlin. Keep us posted on what you find. Note that fluid level is important and sometimes needs to be adjusted ( read topped up) after a fluid change as the ATF works it's way through the system.

Ah, you did the battery/reset thing already. To be honest I know very little about those tiptronic but somehow I have a feeling it is management related. As in software.

Saying that; with all of that management & controls that the tiptronic runs onto, seriously, I can't think of any possible way that a gear could have been damaged. Unless originally faulty from factory then, unfortunate mate :/ Feel bad for you because that is not going to run cheap, removal inspection alone. That (@dealer) might runs you more than simply finding a second hand + swap at your local indy shop. Investigate that before (get quotes)

Raised by NewArt, that manual mode might be a little bit more forgiving - have you tried? If you are not having issues in m-mode, my advice is buy yourself one of those padle wheel (by RAID) and keep it on m-mode. Personally I can't recal when was the last time I've driven the car in auto mode mate, must have been in 2009 or something (when I got the wheel).
