well im getting my tranny rebuild and i was wondering how many quartz does it need. its a 1994 lx auto 204XXX

 

I don't know if it's all the same, but for a '98 I had it was like this:
The total (dry fill)was 6.6 quarts.
Drain & fill was 2.6 quarts.

It may not be the same all years, but it'll give you an idea of how much stays behind when you driain it.

 

Ask your dealership. You'll be there anyways getting the fluid.
ONLY USE HONDA TRANNY FLUID

 

I think the last full rebuild I did used 7.5 quarts
Good idea to go ahead and put a quart into the TC before install, so it doesn't start up dry.
Then after the trans is bolted up and axles are in you can put in 4 quarts, thats enough to start it up, shift thru reverse and drive, holding the brake of course, then shut it off and recheck the fluid level.
