ditchdiggerjcf Posted September 1, 2011 Share Posted September 1, 2011 Anybody know if I can replace my 5 spd tranny with a late model 6 spd in a 91 model pathfinder? Mainly concerned with bellhousing bolt patterns and the transfer case bolting up. Link to comment Share on other sites More sharing options...
5523Pathfinder Posted September 1, 2011 Share Posted September 1, 2011 They will be different. 6-speed trans has a completly different bolt pattern. Now, its not to say that it cant be done. Just some fab time/get creative time. Link to comment Share on other sites More sharing options...
MY1PATH Posted September 1, 2011 Share Posted September 1, 2011 I wish it was a bolt on swap tho. Maybe some sort of bell housing adapter can be made... Link to comment Share on other sites More sharing options...
ditchdiggerjcf Posted September 1, 2011 Author Share Posted September 1, 2011 I wish it was a bolt on swap tho. Maybe some sort of bell housing adapter can be made... I wish they were the same. Adapters would push the tranny back, which means new driveshafts front and rear, and extensive crossmember fab work. Sounds like it would be way too much of a PITA Link to comment Share on other sites More sharing options...

Makes it a more significant job though. Link to comment Share on other sites More sharing options...
RJSquirrel Posted September 1, 2011 Share Posted September 1, 2011 What's the motivation for a 6 speed anyway? Do you get a better crawl ratio or a steeper overdrive? The 5 speed is pretty well matched for the power/torque of a VG engine as is. Link to comment Share on other sites More sharing options...
Slartibartfast Posted September 1, 2011 Share Posted September 1, 2011 Adapters would push the trans back... or push the engine forward. Assuming the adaptor's not a mile thick, you'd just have the motor mounts to mod (probably a fair amount of work, but at least you wouldn't be doing it while lying underneath). You have to pull the engine either way, right? I'm sure the engine bay has a spare half inch up front. Link to comment Share on other sites More sharing options...

No way in hell I'm pulling the motor to replace the tranny. lol Link to comment Share on other sites More sharing options...
nismothunder Posted September 5, 2011 Share Posted September 5, 2011 If a better crawl ratio is wanted it would be time and money head too re-gear the t-case. Link to comment Share on other sites More sharing options...

It's not the crawl speed for sure, secong gear starts are the norm as is. I tow alot and my 5 speed has some issues and a 6 speed is easier to find in the salvage yards.
