That is exactly what I was looking for...is it necessary to unhook the transmission downshift rod and remove the downshift lever? Only reason I am asking is that it looks like the lever is still there in the picture.

no you shouldnt...that pic is actually from the page to R&R the switch...with also directions on adjusting.
