2003 AUDI CABRIOLET Power Trainautomatic Transmission Problems

I HAVE A 2003 AUDI A4 CABRIOLET 3.0 WITH CVS TRANSMISSION. I HAVE REPLACED ONE TRANSMISSION AT A COST OF OVER 7,500 DOLLARS. THE CAR ONLY HAD 65,000 MILES ON IT AND HAD ALWAYS BEEN MAINTAINED BY AUDI DEALERSHIP IN TORONTO , CANADA. THE DEALER TRIED TO GET OUT OF PAYING FOR THE REPAIR AND AFTER SEVERAL ARGUMENTS ONLY PARTIALLY COVERED THE COSTS. THE CAR NOW HAS 110,000 MILES ON IT AND AGAIN I AM EXPERIENCING TRANSMISSION ISSUES. THE PRND LIGHTS FLASH BACK AND FORTH AND THE TRANSMISSION IS WINING AND SHAKY AT CERTAIN SPEEDS. OBVIOUSLY AUDI HAS DONE A POOR JOB OF DESIGNING THIS TRANSMISSION AND REPAIR COSTS ARE RIDICULOUS. I HAVE ALSO HAD SEVERAL ELECTRICAL ISSUES WITH DASH BOARD LIGHTS , BRAKE LIGHTS BURNING OUT REGULARLY AND POWER STEERING PUMP REPLACED. MY ADVICE. DON'T BUT AN AUDI UNLESS YOU PLAN ON SELLING IT BEFORE THE WARRANTY IS UP...
