i took my car to the shop two weeks ago to get the 3rd and 4th gears replaced. The shop wanted to put a new torque converter in just in case. They put the converter in and i got the car back. Two days later it started a horrible vibration. I took it back and they found some washers on the bolts that connect the torque converter. they took them off and gave it back.The car worked fine for a day or two and started messing up again. Then they said the converter might be bad so they put onther in. They also replaced the soleniod. Now the car is messing up again. Now they are saying that the person that installed the alarm shorted some wiring harness thats causing the torque converter to mess up. But i got the alarm installed two months ago. If that was the case wouldnt it have messed up the coverter that was in the car before i took it to the shop? i need help i have been with out my car for two weeks!! What is goin on with my car.
