I just bought a 99 Honda Accord ex v6 coupe and when I press the gas, there is vibration. I feel it more in the seat than the steering wheel, and it's more noticeable in the drivers side than the passenger. It doesn't do it when coasting. Do you think it could be the transmission, or something less serious? Thanks!

 

Welcome the forum Accordcurious83: Possible Transmission, when was it last serviced? Before you do work on the trans, check your motor mounts for ware/worn bushings. Trans service per honda ea 30k miles. If you do it once a year it is better for the trans.
