So does anyone know how much fluid I need for a drain and fill on a 1993 Accord automatic?

I don't want to buy too less because I have to order another quart then and that will cost me another $10.00 in shipping. I don't want to order too much because it will just sit there. The internet offers conflicting advice, I see answers from 2.6 quarts to 4.

Also do I absolutely need a new drain washer? I don't want to do this and then find out it's leaking and have to do it again. I also can't buy it from Honda because the parts dealers charge too much shipping for a tiny washer. Is there some other place I can get these?

Do I do this after driving around for a bit to warm up the engine?

And realistically speaking, let's say in the worst case scenario the bumping feeling is due to the torque converter going bad, is it even feasible to assume a fluid change would even do anything? Is it even possible? For example, if it's totally physical and the torque converter is worn then I don't see the fluid change doing anything. But if it's acting up because the fluid quality or consistency has gone downhill but the hardware is still good, then a fluid change has a possibility of making it better.

I'm not asking for a guaranteed answer because obviously that's impossible, but from anyone who has experience, what goes wrong with the torque converter that might make it impossible for fluid changes to really make it better, that sort of thing.

Stop by the dealership to get the washers, or have them order them. They won't charge you shipping.

 

Honda uses an aluminum washer with the drain plug, it can be reused many times, as long as you clean it up and wipe of the drain plug since it got a magnet inside to catch metal, just wipe it off before you put it back in, and try not to over tighten it and crack the case.
