Transmission Problems

I have a Honda CRV 2002, Auto, 2 wheel drive with roughly 25,000 miles. Been running smoothly. A couple of weeks ago I left the lights on and the battery went flat - totally dead - no lights even on the dashboard. Jump started successfully and drove around for 1 hour and the battery charged up. For 1 week I could start and drive the car no problem.

I then went on a break and didn't drive the car for 1 week. When I came back, it started without problem but now has developed a rough downshifting into 1st gear as I am pulling up to a stop (in the last 3-4 feet before complete stop). The down shifting into 1st is so rough it jerks the car (and occupants). If I keep the car in 2nd gear ('2') it stops fine without the jerk, so I know the problem is in the auto transmission. Acceleration and upshifting through the auto transmission are all smooth.

Anyone have any idea what's wrong and what caused it and what I need to do about it to solve it? Is it related to the flat battery and if so, why did it only appear a couple of weeks after the initial flat battery?

Thanks for the advice

nnot from the dead battery... but try having the trans fluid changed....

You may need to have the TCM reset. (Transmission Control Module).

Did you ever get a good answer to this? I have the identical problem and have been told many things, not sure any of which are actually correct.

Thanks.
