I've been living with a geartronic shifter interlock button split down the middle for some time now and it recently completely broke apart so had to repair. It's $100 for the entire shift **** and shaft assembly or $25 for the button alone from IPDUSA. I went the button replace route and it didn't take too long to replace. Attached are some pictures I took while doing the replacement.

Would this same procedure apply to a 2001 s40? Thanks so much for posting this!
