Why wouldn't you fill it through the dipstick tube? I wouldn't do what your suggesting, I don't think any of the bolts access the inside of the trans to fill it. Dip stick tube only.
The mechanical sai
d it didn't have a dipstickn he said we could fill it there.
I just don't know of I've messed it up. It wont change into third gear
correctly since we changed the fluid.
