My 2001 Toyota corolla jerks when I change gears to reverse the to drive or vice versa.Any ideas? could it be a near future transmission problem? what other problem could it be? or is this normal?

Ethir the idle is to high,or a motor/transmission mount is weak,or broken.Have some one look at the engine,and start the car.Put it in drive,and back into neutral and back and forth.Tell them to look for the engine to tip back and forth,more than 4 inches from where it sets normaly with out a load on it.You can also do this test,by putting it in drive and (ride the brake pedal)hold the brake firm,and gradually accellerate the gas,but have the person looking at engine,position themselves to the side of car(looking over fender)so the won`t be in front of the car,You can do this also in reverse,and you need to.If you get over movement ,then there is a mountor suport,or trans,or more than one,or two of the combinations that are weak,or bad.Also if there are any check engine lights on,it is possible that a solenoid on the trans is bad,making the trans go in gear,to quick,and not gradualy,like it should be.If this was helpful,please let us know,thank you.
