A friend of mine has a 1992 500SEL with 50,000 miles.He told me today about a major repair of its transmission and just ask me to have a try . I drove it tonight and BTW what a luxurious jet! the tansmission is not as bad as expected. What it does is that

1.it shifts a bit harsh at 1-2
2.a bit slip (about 200-300rpm) at 2-3
3.very harsh when kick down from 2-1

This car is regularly serviced by the dealer who told my friend in the recent service that the transmission needs a total rebuild of $2,000 US dollars!! According to its service record, the tanns was seviced 6,000miles ago. I think the trans is fine but just needs an adjustment.I know that involves the adjustment of the modulator and the blowden cable.I have searched the related topics but I just want some more advises about the way to adjust to improve the above 3 problems!! Thanks Guys!!

Transmission Pressure setting
 

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.
