'96 C280 with the 5 speed auto (with manual shift select options below).

The car shifts poorly in and out of third. When being driven normally the car changes from 1st to second without incident, then on the change from second to third the revs rise (either a little or a lot, depending on the throttle position) and after about a second there is an accompanying 'bang' thump in the back and the car selects third. Something less severe happens on the change from 3rd to 4th. The car has recently had a transmission service which did nothing to alleviate the problem.

Any ideas would be much appreciated.

sounds like clutch pack, rebuild time me thinks.

a valve body could cure it though

I'm thinking it would be more cost effective to buy a gearbox from a breakers yard? Would any W202 gearbox do, or will it have to be one from a C280?

I think you'd have to get a gearbox from a similiar engined car. One of the digits after 722.6 (in the gearbox model number) refers to the power output of the engine it's designed to match.

Apparently the transmission is a 722.604. Any idea what (besides C280s) had this transmission, so we could widen the breakers yard search?

Not sure what other models would share this number. Curiously my C280 V6 has a 722.606 gearbox.
