juno1228 Posted July 20, 2024 Share Posted July 20, 2024 (edited) Will an auto trans from a non-turbo 1992 300zx fit in my '95 SE-V6 pathfinder? I see they use the same trans model but I'm not sure if the transfer case will fit? thanks in advance Edited July 20, 2024 by juno1228 Link to comment Share on other sites More sharing options...
Slartibartfast Posted July 20, 2024 Share Posted July 20, 2024 Maybe? I imagine you'd have to open up both transmissions and swap over the output shaft, but I haven't had either unit apart myself. The usual replacement is a first-gen Xterra or Frontier trans. The design was revised a little and is supposed to be better/stronger than the original WD21 trans. No idea how either version compares to the 300ZX trans. Link to comment Share on other sites More sharing options...
juno1228 Posted July 21, 2024 Author Share Posted July 21, 2024 What years are the first gen Xterras and Frontiers? Do they need to be 4wd? I'm only wondering about the 300zx because I found a sort of cheap one used. Thanks Link to comment Share on other sites More sharing options...
Slartibartfast Posted July 21, 2024 Share Posted July 21, 2024 Looks like around '97-'03 for the Fronty, '99-'04 for the X. If it's got the 3.3, that's the one you're after. If it's got the supercharged 3.3, that one's supposed to be built a little tougher, but IIRC the torque converter and flexplate are different from the non-super'd ones, so make sure you get those with it. Again, it may be possible to make the 2WD variant work, but I'd expect it to turn into a bit of a science project. Link to comment Share on other sites More sharing options...
juno1228 Posted July 22, 2024 Author Share Posted July 22, 2024 Hey! Do you know if I should install a new transfercase too? Or will the current one on my Pathfinder still work? Link to comment Share on other sites More sharing options...
Slartibartfast Posted July 24, 2024 Share Posted July 24, 2024 I would keep your old transfer unless you know there's something wrong with it. The later transfer will work if needed, but you may need to swap the lockout plate and shift linkage to make it work right. There's a difference in chain design between early/late transfers, but I have not seen evidence that one is actually stronger than the other.

adamzan Posted July 28, 2024 Share Posted July 28, 2024 In theory all you'd need to do for the 300zx one is swap the tail housing and output shaft, but I don't know what other internal things they changed. Also the gear ratios may be different and not as applicable to a truck application. Link to comment Share on other sites More sharing options...
peejay Posted July 28, 2024 Share Posted July 28, 2024 Don't quote me on this, but according to this site, the gear ratios (and nearly everything else) should be the same: https://hgmelectronics.com/blogs/hgmelectronics/re4r01a-and-re4r03a-transmission-control-and-the-compushift-sport Link to comment Share on other sites More sharing options...
