Merc S280 Gear shift results in car jerking Good Afternoon everyone,
My Merc S280 is facing some gear shift problems. It jerks quite hard when shifting from 2nd to 3rd gear. Mechanic said may need to overhaul. Anyone done this before? How much would it cost? Thanks in advance guys. |

Re: Merc S280 Gear shift results in car jerking Happened to my W124 before. It was the longshaft couplings & u-joint (not too sure with the correct terms), and not the gearbox afterall.

Re: Merc S280 Gear shift results in car jerking Before jumping into an overhaul....check all these first
Prop shaft coupling ...both gearbox mounting Vacuum modulator pressure, try turning anti clockwise.a bit by bit till smooth After all these You can decide weather to overhaul or change a second-hand gearbox

Re: Merc S280 Gear shift results in car jerking Good suggestions raised by Schenks.
The propeller/drive shaft coupling = flex discs. These are wear and tear items so good to check their condition first. If cracked, change and see if shifting improves. Gearbox and differential mountings - Likewise. Vacuum modulator for gearbox - Another likely candidate. I would add when was the last time your automatic transmission was changed together with the filter? You may want to do that as well and observe if it improves before going down more drastic routes.

Re: Merc S280 Gear shift results in car jerking I'm no expert by far, would it help to have the OBD scanned first to see if anything's wrong?
