“TRANSMISSION LOCKS UP OR HARD DOWNSHIFTS AT SPEEDS OF FIFTEEN MILES OR BELOW ON DECELLATERATION. FOUND RECALL CAMPAIGN NUMBER 99V138000, DATED JUNE 02, 1999, HOWEVER WAS TOLD MY VIN NUMBER WAS NOT ON RECALL LIST. I CHECKED THE INTERNET AND FOUND HUNDREDS OF BLOGS OF COMPLAINTS INVOLVING THE EXACT SAME PROBLEM. IF THIS IS A KNOWN FAILURE AND A RECALL WAS ISSUED WHY NOT TO SOME VEHICLES AND NOT TO ALL TRANSMISSIONS THAT WERE AFFECTED. THE JAGUAR PERSON I SPOKE TO WAS VERY DEFENSIVE AND WOULD NOT LET ME GET A WORD IN EDGEWISE, KEPT REPEATING THAT MY VIN NUMBER WAS NOT ASSOCIATED TO THAT PARTICULAR RECALL. THIS IS A TRANSMISSION PROBLEM THAT HUNDREDS OF OWNERS ARE FACING AND SHOULD NOT BE ASSOCIATED TO A PARTICULAR VEHICLE. I UNDERSTAND THAT THE XJ8 HAS THE SAME TRANSMISSION AND HAVE THE SAME PROBLEM ASSOCIATED WITH THE TRANSMISSION. *TR”
