john, sorry to hear about the prob.
yes, seems $1300 was good invest, especially if in CAD $.

what will they install? MB new? MB rebuilt? junkyard dog?

you bought the 230 new, right?
same 5-speed auto-box as used on 230 komp?

the figure ive always heard here in ATL is $2500 for "mr MB" to fix the box, plus all associated labor. mr MB wont touch the car, only the box.
