Not sure what model I have yet, 4 cal gas motor 2 speed manual trans. My transmission input shaft slid out of the clutch disk and into the transmission. I can pull it out and it engages in the trans splines, but it easily slides right back into the trans. I have to pull the trans to get at the back of the input shaft to see what went wrong, but I can't get the trans to come forward out of the differential. I have removed the top cover, all the bolts, lifted, jacked and even tried a ratchet strap to pull straight back. So far I got about a screwdriver blade of space and no more. Is there a trick to get them apart?
