jeeplover Posted October 4, 2020 Share Posted October 4, 2020 What manual transmission goes best with the 4.0 liter inline 6. Link to comment Share on other sites More sharing options...
jdog Posted October 4, 2020 Share Posted October 4, 2020 depends on year, model, plans for the vehicle, Link to comment Share on other sites More sharing options...
ghetdjc320 Posted October 4, 2020 Share Posted October 4, 2020 AX15, NV3550 and NSG370 all bolt up easily but as jdog mentioned, let us know the use and application. Link to comment Share on other sites More sharing options...

omega_rugal Posted October 4, 2020 Share Posted October 4, 2020 the AX15 may be the best choice... a 95+ with external slave Link to comment Share on other sites More sharing options...
jdog Posted October 5, 2020 Share Posted October 5, 2020 most members will recommend ax-15 cause it works and can be found easily enough. Link to comment Share on other sites More sharing options...
Dzimm Posted October 5, 2020 Share Posted October 5, 2020 I would agree, the AX-15 seems to be the best manual trans offered in the XJ/MJ. Should be fine for any amount of hp you can get out of the 4.0 Link to comment Share on other sites More sharing options...
ghetdjc320 Posted October 5, 2020 Share Posted October 5, 2020 AX15 or NV3550 would both be fine. The external slave bellhousing started in 94. Personally I’d just spring for a new ax15. Went through several uses and rebuilds before I got a good one. Keep in mind too that the XJ/MJ ax15 clocks the transfer case down slightly for better clearance although you can make the YJ/TJ version work too.
