I am looking at a used e46 with high miles (122,000) and want to know if SMG should be a concern. I know the miles are mainly highway miles in this case but I will be pushing the car hard since plan is to turn it into a track toy. I previously tried this car at the track and loved the smg at the track. Thanks!

 

smg failures were like 6-7 years ago on these but anything that involved at 122k can go at anytime. it's a crap shoot. gl with it

 

122K is a lot of miles but remember that the SMG is the exact same part number as the manual tranny, with a hydraulic arm on it. So, really the only thing that can fail is the hydraulic arm from my understanding. Because of the SMG's precise shifting, clutch wear is minimal.

I wouldn't worry too too much, but go get it inspected!
Oh, and if it's an 01, make sure it underwent the rod bearing recall

It's one of those things that is random. It is not a usual part to fail, but stuff happens.
