It is your car, you can use, however I personally would not. You may have a bigger problem if it doesn't work.

I believe you have drum brakes on the back. Not sure. If so, it probably is the automatic adjuster is frozen. This comes into play when you go backwards and apply the brakes. It is used so that the emergency brake is in proper alignment, that is, it only takes a few clicks before the emergency brakes start being applied. If there were no adjuster, as the brakes go old, you would lose the emergency brakes entirely.

I suggest you have a transmission shop take a close look at your vehicle. That year accord with a v6 and automatic transmission had a recall for the transmission and your problem seems to be a slowly dying tranny.

Take it to an auto parts store
and exchange for a reman

If you are unable to get it out of park and into any other gear including reverse check the brake pedal
switch. The brakes have to be applied on most automatics in order to get the car out of park.
The switch should be attached to the brake pedal
under the dash.

check fuses or see if something might have got jamed in the track and also try movin the part where the seat belt moves back and forth to see if the motor is dying

thats right , just drain and refill, use HONDA trans fluid, takes 3 quarts.

scan it.check the throttle position sensor.and check air duct that goes to throttle body. for leaks holes and cracks.make sure its tight.

run engine codes, had same issue once before it was bad computer good luck

no and should be easy compared to what your used to.  Just put a small dap of silicone at the 4 points the cam bearing caps meet head(don't remove the caps) you will see what I mean when you get into the job. I also recommend distributor  o-ring they leak often and  are also fairly easy. just mark the dist. It will only go in 2 ways it has tabs to align it not gears.
