Q: It makes noise when I hit the brake my mechanic thinks it's the transmission

asked by on

My car has 116000 miles It makes a loud noise when slowing down my mechanic said this model year has a problem in the transmission and only the dealers or someone with a special license is allowed to fix it. Is that the only thing causing this problem? How much is to fix it at the dealer? How much should it be at a licensed mechanics? How can I find a shop that's licensed to do that work? Thanks

My car has 116 miles.
My car has an automatic transmission.

If you cannot locate an authorized independent Mercedes repair facility other than a dealer then I’d recommend going to a dealer for this problem. I would suggest going to a trained Mercedes shop for transmission problems, otherwise you may not get a correct diagnosis and repair. These transmissions take a specialized scanner to check and test this vehicle. Not many shops would have the tools that are needed to pinpoint the issue.

However, If you’d like a second opinion on this, consider having one of our mobile technicians diagnose the noise firsthand. Best of luck.
