    Trasmission stopped working in all gears while travelling at 40 mph. Engine ran, but each gear felt like I was in neutral. Problem was a spring which cracked and set off a chain of events which killed the pump and other key components. Mechanic said the disc type spring was of inferior quality. Tranny had to be completely rebuilt including replacement of upgraded spring.

    We bought this 2001 Mitsubishi Diamante LS from a used car lot and it is a piece of shit. The Transmission went out 60-90 days after we bought the car for my son. We have put I don't know how many other transmissions from 2001 Mitsubishi in this car and they all have the same problem. To install a rebuilt transmission is $2600.00 and that is more than the car is worth. Every where you read on line you find the same story, the 2001 Diamante has transmission problems. Why hasn't there been a recall?

    When accelerating from a stop sign or red light, fails to shift in to first gear, slowly shifts to 2nd 3rd and 4th gear, sometimes shifts hard enough in to 2nd that it will spill your coffee. Pump has taken a poop a couple of times. Repeated drive, timing, power steering, AC BELTS all REPLACED SEVERAL TIMES, alignment failure repeatedly. A rebuild is imminent.
