The transmission bolts are horizontal, how do I add fliud into it? hehe...dumbass here.

 

You need a pump as the filler inlet is on the top of the case. But why do you think you need to add any? Did you have a leak?

 

I add the fluid by running tubing (find discarded but not used tubing in the operating room) from the engine compartment down to the filler opening and a funnel type device at the tubing end.

I suppose auto shop hoses can be used, etc.
