My 94 accord is making a thumpin sound behind the front seats and I can feel it when I put my hand down thumbing right in the middle just behind of the front seats. I have no idea if it could be the transmission or what. It is a straight drive. Does anyone have any idea what that can be?

 

When does it thump? When you put it into drive, while you are driving or only at certain speeds?

There are no drive train components behind the front seats, but you could have worn out transmission/engine torque mounts causing the engine to rock and the exhaust to move and bump up against the floor behind the seats.

Pop the hood, have someone else start the car, step on the brakes and put the transmission into drive and see if the engine rocks, while listening for the thump. Do not stand in front of the car, stand off to the side, just in case your brakes aren't up to par.

 

Thank you I checked it out and I think you're right on with the mounts being wore out

 

Check to make sure your rubber exhaust mounts holding the pipe are in good shape as well and not missing or torn. Sometimes a combination of front motor mounts and the pipe "free ballin" join forces to cause noise.

 

Thank you guys
