I haven’t drove my 540 in 5 months because of an unrelated issues (front drive shaft snapped and destroyed my pan) but today I went on a drive and the car slipped every gear after second gear then I got a drivetrain malfunction and was stranded in the road. Pretty sure I need a new transmission although it doesn’t make sense the car only has 60,000 miles on it runs fine just doesn’t drive fine anymore, any thoughts cause I’m very confused 😕

I am going to venture to guess that since you snapped the driveshaft, you drive it pretty hard and have it tuned pretty aggressively. You have a lot going on there and not nearly enough information to guess, but I would not assume you need a new tranny since it's slipping through all gears.

Is the tranny tuned?

My bad, I failed to mention the car is actually stock, (has a stage 0+ tune and no transmission tune) im more of a calm driver I don’t really beast on my car, the night my front drive shaft snapped I was doing 65mph.

Got it. It may just be a transmission software update? You probably don't want to hear this, but I would take it to the dealer.

Anyway, sorry for not being more helpful, be sure to follow-up this thread with what it is.
