Hi,
Before I pull this thing out, I want to make sure it's the trans. Yesterday I took the car out and everything was fine driving down the freeway. After getting off the freeway as I was pulling away from the stop it felt/sounded like something was going to come thru the floorboard of the car. I don't know how to describe it other than it sounded like the drive shaft was hitting the floor of the car when I was moving. I checked the drive shaft today and the joints are fine as well as the rear end. The only thing I notice is when I put the car in reverse it hits pretty hard and it doesn’t matter if it's from park, neutral or drive.

Thanks
Brian

 

Check your tranny mount.

 

Did that when I checked the driveshaft. Also checked the converter bolts.
