Now I barely have drive gear, is it possible that it's still low on transmission fluid? After I put six quarts in already, I replaced the filter. Also, I think I completely drained it.

If you drain the unit completely it needs more fluid than six quarts.

Here is the capacity and fluid specs:

Total oil volume

(Transmission and torque converter drained)

Approximate liter. 9.5 (10 quarts).

Here are the instructions and how you can add fluid to help fix the problem. Check out the images (below). Please let us know what happens.
