Yeah, I had that happned to me one.
Right at the "last click" of an ignition key just right befor "Start". All the lights on your panal should comes on. If it doesn't or come up sometimes, I'm pretty sure its the ignition swich.
Mine sometime happen during the driving as well, all the TACH and SPEEDOMETER shut down. Replace a new ignition switch, prolem fixed
On the Tranny. If it shift harsh , so to replace the fulid a few times maybe 2,000 mile or so and put some conditioner. See it will help a bit. Because there will be some old fulid left in Toque converter.
I have a same problem with Accord 90, I bought it at 120K. The tranny shifting hard. Changed the fulid a few times within 3,000 miles after I bought it, add conditioner - now run fine.
