yo2001 Posted May 30, 2003 Share Posted May 30, 2003 Ok, I broke my trans last week. I took it apart this week and found fourth gear all chewed up. (10 teeth missing. ) But what puzzling me is that I was not in fourth gear when the trans broke. how can that be? Does the manual trans ride 4th gear all the time since it's drive gear or something? BTW, myt trans is early 280Z 5 speed. I alos like to convert the overdrive to later model. (somehthing more than .86) All I have to do is to swap the gear set off later trans for the 5th gear right? Thanks Quote Link to comment Share on other sites More sharing options...
Mike C Posted May 30, 2003 Share Posted May 30, 2003 Do you mean the input shaft? 4th gear is 1:1. The mainshaft is locked to the input shaft with a slider. Technically, there is no 4th gear gear set. When NOT in 4th gear, power goes through the input shaft and into the cluster gear for EVERY other gear.

yo2001 Posted May 30, 2003 Author Share Posted May 30, 2003 Ok, I think I'm getting it. Well, I broke the gear right behind the input shaft bearing. So the trans ride on that gear pretty much all the time? that would explain why I broke it when I was in 3rd gear. Quote Link to comment Share on other sites More sharing options...
