Hello all. I have a question about what I think is a backwards minded Sherman Step up Step down. The reason I say backwards minded is because it shifts exactly 180 degrees opposite of the diagram. Shifter against the housing it will shift forward. Pull to neutral and pull away from housing & it will shift forward and backwards. When pulled out and forward it roars VERY loud. Is the a such thing as a copy cat aux trans or did someone make a weird and terrible mistake and reassemble it using a mirror? Oh, and I ve been using it in one working range for 9 years. Ready to fix it. Thanks in advance y all.
