W210 Lost 5th gear in Autobox...help
 

Hi,

I have a 1997 E320 with just 53000 miles on the clock and I've noticed recently that the autobox has lost 5th gear. The box is still shifting smoothly, just not into 5 th gear.

Also I've noticed that the box will not kick down to change gear, although it will manually shift down if you use the auto-box gear shifter.

Whats going on and what's involved in fixing this problem and are the two problems related ??

Many thanks

Diagnoses starts from the outside first, you have to retrieve ANY codes.

D you have summer winter switch on console in winter?
