Tranny problem, request info.

Hello all,

It looks like there is a lot of experience here, so I hope someone can diagnose my problem.

On my way back from vacation, my 94 accord started skipping a beat once in a while when pulling long hills. I thought it was a bad plug or wire, so I kept driving. It gradually got worse (luckily I was near home by this time), until it started making a medium pitch whine, kind of like a gear not quite engaged. The transmission was basically out of fluid when I checked (oops).

I re-filled, and the car runs fine in D3, but when it is in D4, and shifts into the highest gear, it makes the noise.

I checked the solenoids, and they clicked when I apply 12 volts, but I'm not sure what else to check.

My question is do I need a complete new tranny, or is there something small I can replace or fix to get the car back on the road?

thanks in advance.
Allen
