I'm looking for a 36 tooth Speedo gear(pn 52067636, short shaft for 1993-2002) for my 96 ax15. I just swapped in 3.55s from an automatic and have 27.1" tires and according to go-jeeps speedo chart I need a short shaft 36 tooth speedo gear, even though the auto with 3.55s and 27.4" tires came with the 35 tooth speedo(it would be a lot closer to correct mph than the 31 tooth I currently have). Also, are the automatics and manual speedo gears interchangeable or tranny specific?
