Can I use 98 outback manual center diff in my 01 rs manual trans?
I think the answer is yes but just want to verify? Thanks

Thus is what confuses me? 3 different subaru specialty shops say It will be alright. I dont know much at all about trannies and gearing nor what the viscous coupling has to do with final drive. I want to believe them but need a concrete answer before I go throwing parts on a transmission that werent intended for it.

after being elbow deep into my transmission i am going to say that unless your dealing with the wrx 5mt, where the center diff is not 1:1, it should work fine as long as it slides on to the shafts
on the legacy's & rs's the center diff doesn't effect the FD that's all taken care of by the ring and pinion gears in the front and rear diff's |

Look at both transfer sections (bolted onto the main gearbox). I'm pretty sure the 98 was a "phase II" type, easily identified by the lack of a flat access panel bolted down on top. I know the 01 will be a phase II. If both are the same, the center diff will literally plug and play.
If the 98 trans has that access panel, you will need to swap the entire transfer section, including the housing and shift selector shaft, along with the center diff. They are not interchangable by themselves. FWIW, this can all be done under the car, without pulling the trans out completely. Jay Storm |

98 Outback tranny is still a phase1 and uses a different center diff than all the 99+.
You cannot use a 98 on your 01, sorry. phase1 is up to '98. Phase2 is 99+. Put that Outback tranny in your RS!!! You'll love the shorter 5th gear! People, please do NOT confuse "Outback" with an "Impreza Outback Sport/Outback Sport (OBS)." |

I thought 98 was the first year of the phase 2 trans. Maybe it was one of those mid year things.

This is why the OP should look at the trans for the access panel on the top.
It most certainly CAN be done, as I just did it a few months ago on my Forester. The entire transfer section has to be swapped with it, but it can be done. '00 Forester using a 96 Impreza center diff (and housing). Jay |
