Transmission Not Go Into Gear problems of the 2003 Mini Cooper S

Failure of 2003 Mini cooper manual transmission. My car has been under regular maintenance. I first noticed the car losing power going uphill, then it became difficult to put the car in gear. Next morning I was unable to get into reverse, was extremely difficult to shift and some gears could not be engaged. At a stop light I began hearing a very loud grinding noise, like metal in a blender, the car would not engage in gear, I had to be pushed out of the intersection. The dealer offered nothing. My private mechanic found metal shreds throughout the transmission. Said a bearing had come loose and destroyed the interior of the transmission, all at 65k miles. He also said the engine could have failed while on the freeway at high speeds and this could have been life endangering. Also the power steering pump went at 30k miles. Both very costly repairs and the transmission locking up a very serious life threat. The replacement costs for the transmission were $3k and that was from a private mechanic. Online research shows a plethora of consumer complaints and information that Mini cooper knows about this. Neither the local dealer nor corporate office would offer any help in replacement costs.
