Hi Davis,

I recently sent my '92 300SEL for a trans overhaul excluding the valve body at 97KMiles and my immediate reactions was the changeover is a little jerky like what you are experiencing.

The pressure setting are given for all Transmission models and thus kind of factory setting standard.

I have been told that at standard factory setting the transmission will keep the running life of the transmission going although its a little jerky during changeover.

However you can set it to be softer at the expense of early wear and tear. How true is it I dont know and mybe some senoir members can advise on it.
