yes im having trouble with a transmission on my car.

What is your question?

my problem is is that my trans. was working fine and the next time i started and drove it, it wouldnt shift into third,i changed the fluid and all to no avail. even though my fluid didnt have any shaving or smell burnt at all. i tried to change the two single selenoids on the transmission to no avail, but was wondering if maybe it had someting to do with the lock in selenoid or shifting selenoid. i cant help but think its an electrical failure the way it had quit. no problem with tranny slippng or the like before. i checked the two latter selenoids i was talking of that i didnt replace and they both seemed to be engaging when i put a hot wire to them. the question i guess im trying to ask is that in the cars electrical system what is it that put the spark to it or makes the wires light up going to them. does the car have to be rolling at a certain speed or does tach have to be revved up. etc. for there to be a spark going to them to make them kick in, just in case there may be a fault or short in my wiring. (or if this could even be the problem?). but like i said, i had no slippage, no smell of burnt or dirty fluid. its like it just happened all at once. i know hondas of this year have had tranny problems. but nothing i read seemed to apply. any thing that you could tell me would be greatly appreciated
