Auotmatic trans. questions
 

Last summer my trans would not go into reverse at all and engage into drive with some hesitation until the car was completely warmed up, then it was okay. Before I put it in storage for the winter, I added a can of Sea Foam auto trans conditioner, and that has cured the hesitation problem, only now it engages into gear very abruptly in both reverse and drive. So my question is: do I leave it alone and let it bang into gear, or drain the fluid and add new and hope it cures my problems? TIA for any help/advice.
