how to add trans fluid to manual trans?

[hpcbmw]

I need to change the trans fluid on my 4 cyl 5 speed manual trans 93 mx3. Every car i've done this on in the past has a fill hole big enough to stick your finger in to check the fluid level. From looking at the pics in the manual, the fill and check hole appears to be pretty darn small. How do you fill 80 wt oil from a hole that small? Must take a LONG time. Also - anyone try molybdenum as an additive in these trannys?

I've been searching all over this site and keep finding links that are no good - I think the links were from before the site was re worked. Anyway, there's lots of mention of a 23 mm bolt head to check and fill the trans, but the check/fill head in my car is 12 mm.

I see posts about re filling via the speedo cable, I'll look at that possibility this afternoon.

That's where you fill it. Remove the vehicle speed sensor and get yourself a clear, flexible tube to funnel it through.
