I have a 77 G10 Chevy with a 3 speed manual transmission. I got slider door with windows from junk yard and just painted it with plasti dip artwork on the outside and fixed up the inside. I will post pics later on
But now just getting to work on it and today while fixing rust under the van I noticed it might be seeping tranny fluid. I drive it quite a bit. I notice a little fluid seeping.
It looks like a very very slow seeping not a big leak, but I am thinking of going on a road trip so I want to top it off. They guy i bought the truck from did not care for it properly, it runs well but after driving it for a year I think i should make sure that fluid if full.
I want help to confirm if I am right in see what is the fill and drain plug before I start messing with it. I also need to know what fluid is needed for a 77 manual
Is this the fill plug? on the right passenger side of the tranny about half way up. but the thing i see there has a square headed bolt.
