First time- transmission failed- new one installed under extended warranty- has gone bad again last week- they tell me the coolant is leaking into the transmission and has ruined it, the gas tank needs replacing, new radiator, new catalytic converter, new U-joints for the second time. My extended warranty has expired- they are telling me that I need $8000 worth of repairs to fix the problems. That is more than the vehicle is worth with 155,000 miles on it!!! please help.
