1992 400E ticking when in reverse
 

I have a 92 400e with 175K (2nd owner) and have maintained the car very well. I have a ticking sound when in reverse and mechanic is saying its a clutch plate? or something to this effect (says could be just the front or front and rear components) he is stating $1600 (if only front) to $3800 in repairs depending on the severity...can anyone shed some light on this? Is this accurate? He says common, as he has done it twice to his 300e with 300K on it. Is there a lower cost path to fixing it? I do trust them as a shop but know they are towards the top of the cost factor index for an independant.

Don't wait too long or the higher option$$$$ will be the only option!!!!

Reverse clutches worn out...approx 10-12 hrs & parts for the reverse clutch only repair.

Reverse Clutch Pack...Mine was doing that too. If you don't get it fixed you will eventually lose Reverse.

A suggestion: Spend the extra cash to have the whole tranny worked through. Dont' dare pay to have it removed and reinstalled with the tech only replacing your reverse packs. You are at the mileage where you likely have wear on other forward drive clutch packs. You probably have some seals ,links and cables that could stand some attention too. Since they are gonna open her up anyway, have them go front to back.

I did that with my 92 400e at about 168K (I was experiencing reverse ticking, slow engagement of drive from reverse and occasional slipping between 3rd and 4th during extreme acceleration)

I got out of my shop for just over 3K ( an independant MBZ only shop) ...that included replacement of all the worn packs, every seal and gasket, cables, etc....The slow engagement to drive was fixed by replacing a pin that was designed too long from the factory. They pulled it and fabricated a shorter pin (forgive me, I don't remember it's proper name).

net, net...she shifts crisp and clean. Good luck
