Transfer case differences (1 Viewer)

Is the actual housing of the transfer case different between the 3 and 4 speed transmissions? I have some cases and am trying to identify what they are. Thanks

IIRC there are some minor differences in the nose cone & the ribbing depending on what year case. There are different size idler shaft being the main thing that will make a case unusable depending on the size idler shaft the gear set you want to use is. The 4spd tcases use a diffrent spline count on the input gear than the 3 spd tcases however there are some conversion gears out there with the 4spd spline count & the 3 spd gear cut. The low range on the 3spd & 4spd tcases is different so the gear sets can switch cases if the idler dia matches but you can not mix match gears between 3spd & 4spd.

Somewhere on Mud is the Four Wheeler magazine article from the 1980s (written by a 'cruiserhead) that shows all the FJ40 xfer case differences. There were many small and larger changes through the years, mostly aimed at making them stronger and quieter.

That's a great article with a lot of good information! Thank you for posting that response. I believe I have some of all three later types but this will allow me to verify.

Is that Roadkill Garage Freiburger that wrote that article? Who knew he was an original Cruiserhead?!
