Hi,
Well I did some more fault finding tonight on my W126 and it turns out I have 12v going to the kickdown solenoid when B or the kickdown switch is engaged, but no 1st gear.. So, my question is how easy is it to replace the solenoid? is it just a case of unbolting the big bolt above where the wire goes in and thats it? Will I lose fluid when doing this? Thanks, Ben.
