Guest ZmeFly Posted January 2, 2004 Share Posted January 2, 2004 Does anyone know if these transmissions are the same besides of course the bell housing. They both take the same clutch kit. I was wondering becuase looking at the transmission calculator, the 84-86T has better gearing then the 83 does. Thanks for any insights.

Mike C Posted January 2, 2004 Share Posted January 2, 2004 The input shaft is longer on the later trans. Won't work. Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted January 2, 2004 Share Posted January 2, 2004 Do you think the input shafts could be changed out? Would this be practicle? I'm going to have my trans redone later this month and now would be a good time to make any changes. Quote Link to comment Share on other sites More sharing options...
Guest ZmeFly Posted January 2, 2004 Share Posted January 2, 2004 That they are not directly interchangeable. Id like to know myself, what Cody asked, if the input shafts could be changed out. Quote Link to comment Share on other sites More sharing options...
Mike C Posted January 2, 2004 Share Posted January 2, 2004 You cannot change the input shaft unless you change the gear ratio. As the input shaft gear and the cluster gear combine to give gear multiplication. This puts you right back where you were. What might be possible would be to completely disassemble the trans and have the longer shaft shortened and splines turned down to make a new pilot. Don't know how hard the input shaft is and how much that would cost. Not sure if the trans case is the same either where it bolts to the bellhwouing. The easiest solution might be to have an adapter machined to adapt the trans to the L28 bellhousing. BUT, if you are going to that trouble, I would buy a brand new Ford Motorsport T5 and adapt it to the L28 bellhousing. You would have all of the World Class upgrades and closer ratio gearing as well. All for $1200. Check out Advance Adapters and see what sort of Transmission or Engine adapters they may have for Nissan. Transdapt might be another good source.
