Having trouble with transmission not shifting properly .
I'm trying to get some feed back with a rpm error .
I replaced the transmission on my 2001 clk 430. The car rides but not shifting properly all errors were cleared and one keeps popping up something to do with
Rpm revolution or something . I also have 20" rims on it and added spacers to the front spring to lift the front a little. If any one has 20" on 2001 clk430 please give me some feed back on tire sizes offsets and if you had to replace shocks or any type of transmission module programming. Any help would be greatly appreciated.
Best regards!
