I can start the car just fine and I can move in reverse fine but as soon as I put it in drive it only goes up to about 20 maybe it sounds like it's not shifting and the engine is reving but I don't go any faster a friend said it could be a sensor or a valve cap but I can't take it in anywhere to find out the problem because two wheels are flat and I have no way to inflate them. Thanks I hope you can help
My car has an automatic transmission.
