Transmission Issue
Transmission Issue
Evening Benz owners,
I have a problem with my C200 03 Coupe - It revs high when the gear changes from say 2nd to 3rd.
I've only had it for a month and have had the auto transmission replaced, it is still under warranty.
I received this.... P2221 The signal of component Y3/6b1 (Transmission oil temperature sensor) and or Y3/6s1 (starter lockout contact) Is implausible....When I had the car diagnose,
Can someone tell me what it means please as I'm getting stressed out over this.

for a 2003, you would have a W203. You might want to repost in the appropriate category to get relevant answers to your problem
