Transmission Bolt Size Question

Hi,

Can anyone remember what size the fill bolt is on 88-91 Civics? I think
its right around 17mm, but I want to know for sure because I am away
from my tools and want to just buy/borrow a wrench for only that bolt.
I've got a transmission leaking due to a new driveshaft not fitting
correctly in my transmission and I want to top it off before I put
another ~120 miles on it on my way to where I work on the car.

Thanks a lot,

Mark

It is a 17 mm bolt head on my 91 Civic LX manual transmission.

Also, I have a vague recollection that the last time I changed the transmission
oil I couldn't get a socket and ratchet in there and so had to go out and buy a
17 mm open end wrench.

If possible, bring both a combination (open end and box) 17 mm wrench and 17mm
socket+ratchet to the job.

Thanks a lot Caroline. I'm going to just get an combo wrench. That's
what I've used in the past. I think there are such things as low profile
sockets, so with one of those and a slim breaker bar you would be in
good shape to deal with extremely stuck filler bolts. I previously had a
heck of a time getting the filler bolt free on a '91 DX sedan. I had to
use a vice grip clamped down as tight as I could clamp it, and I struck
it with a hammer.
