W124 estate e280 - 93 - strange thing...!!

[lukather]

Well give the ol girl a good looking over at the weekend... she's just had two new wings and wishbones so i thought i'd check rear end grease a few nipples...!!

Shes been grabbing at gears recently and put this down to old age and 170k... the gearbox oil and filter were changed at w124 18months ago so i know shes ok that side thought it may be the dif..

Well I put her on front and rear ramps...she immaculate underneath no a sign of rust...re greased brake pipes...etc

took her out on the roads...and she's running better than ever...smoother gear changes than in a long time..and just sounding very quiet... even the engine.....

Anyone shed light on this phenominon..!!! its not just me i can assure you..

many thanks

vacuum is the key to smooth shifting autos.

At your miles the engine mount may be tired/sagging and causing a vacuum pipe to stretch causing a slight leak/input of air.

By jacking front and rear of car you have temporarily caused engine/gearbox to move on their mounts thus relieving the previous stretched vacuum pipe,
thus making proper seal again. But it will likely not last.
