Please Help with 92 Accord LX trans problem

My 1992 Accord LX transmissions D4 light every once in awhile will go out for a couple of seconds in which the transmission disengages for just a second and the D4 light comes back on. I jumped the connecter with a wire to retrieve a trouble code. The check engine light comes on and doesn't blink but the D4 light comes on blinks once pauses and blinks again and again, like it would be a code 1. I was wondering if anybody could help me with this so I know what to repair.

Thanks for any help.

Update: Yesterday when I drove it (at about 50 mph)the D4 light blinked on and off about 4 or 5 times with in about 30 seconds, when it was doing this it felt like the trans. was slipping/disengaging/torque converter unlocking something like that. I took at on a 20 minute trip and it only acted up that 1 time which was about 3 or 4 minutes into the trip. The engine was cold when I started out. When I got home I jumped the connecter with a wire to retrieve a trouble code. The check engine light comes on and doesn't blink and the D4 light didn't even come on this time.

Today: My Dauther drove it and it don't even mess up. It will do it again though.


Thanks for any help.
