Gscottyengineering Posted April 13, 2023 Share Posted April 13, 2023 (edited) Hey ya'll! Starting this thread to document my latest project which is DIY rebuilding a junkyard RE4R01A transmission from an '01 VQ35DE pathfinder to revive my recent project R50 purchase with a known bad high clutch pack. I want my R50 to be a Colorado mountain adventure vehicle I can trust to drive far from home and have peace of mind towing a small camper redlining up high altitude inclines without worrying about having a high mileage black box for a transmission. I've never done this before but here are the main resources I'm using for information: 1) Nissan FSM off NicoClub, AT section for diagrams and basic procedures 2) Curmudgeon Transmission's excellent 1 hour and 37 minute video going over the entire rebuild process in detail, with gotchas. Parts list: - Junkyard transmission, high mileage - $150 - PA Cargo / Transtec overhaul kit - $130 - Borg Warner band, - $15 (even though original looked totally fine, it's old so replacing it) - Raybestos high energy frictions - $80 - PA Cargo bushing kit - $25 - Brand new Transtar front planet assembly (one planet has more play than the rest after dissassembly)... I bought the last one in stock anywhere...! - $70 - TransGo valve body shift kit upgrade - $50 Yesterday I pulled most of the transmission apart into component assemblies before deciding to stop and get a better pair of snap ring pliers. My plan is to attack each complex component assembly containing seals, frictions, springs, etc individually to avoid having a giant pile of similar looking parts that could potentially get mixed up. I'll bounce back and forth between Curmudgeon's disassembly and rebuild videos for each major component, doing one at a time until I've got a pile of assemblies ready to go back into the case. Images from 1 hour into the disassembly - Note wear found on the reverse drum bushing, steel is showing through the copper. Incidentally there was a normal amount of copper colored glitter in the pan (no chunks), hoping it's just that and the front planet washers which are known to wear: https://imgur.com/a/2YQFQA7 Edited April 13, 2023 by Gscottyengineering details 4 Link to comment Share on other sites More sharing options...
98dreamer Posted July 8, 2023 Share Posted July 8, 2023 Hey, bro. I'm in the middle of mine, as we speak. Some thing I'm curious about, how the eff do I find out how many tooth/lugs does mine have? I've seen things with 42 tooth and 12 lug and no idea where to count what... Ps. I grenaded my planetaries Link to comment Share on other sites More sharing options...
