2k2 6 Speed Transmission Fix/Upgrade (picture heavy)
Disclaimer: If you attempt any of what you see from my post, you do so at your own risk. The following is a summary of my experience.
The Car: 2002 Maxima SE
Transmission: 6 speed, HLSD, RS6F51A
Mileage: 174,000 mi. (approx.)
Situation: November 1st, 2014. I jumped in the Maxima, running late to a funeral in Tennessee. Pushed clutch to floor and started it. I could not get gear shifter out of third gear no matter how hard I tried. Something was obviously broken in the transmission.
After a lot of online research, I purchased a 29,066 mile 6 speed, HLSD transmission from a 2006 Nissan Sentra Spec-V (p/n RS6F51H) from http://car-part.com/. Kindly gentlemen cargo shipped it from a junkyard in Arkansas to my door step in North Alabama for $XXX (will update when I remember it). The following were the only differences in the two transmissions: (1) bellhousings were different, (2) final drive ratio were different (3.812 vs 4.133), (3) Maxima – 1st & 2nd gear dual synchro, SpecV - 1st gear dual synchro, 2nd gear triple synchro.
To Do List:
(1) DOCUMENT EVERYTHING WITH PICTURES!!!
(2) On RS6F51H transmission, swap to Maxima bell-housing
(3) On RS6F51 transmission, swap out SpecV final drive for Maxima final drive
(4) While I’m at it, install Fidanza Lightweight Flywheel and RalcoZ Lightweight Underdrive Pulley

Work Setup:
- Set each transmission on cardboard covered work bench side by side (cardboard to protect mating surfaces on transmission and soak up any grease/oil/fluids)
- For fasteners, blow up and print out FSM pages and glue to cardboard. Poke fasteners through on board where you take them out of transmission
- Take off parts from each transmission at same time, label in Ziploc bag
- For large parts, label and place in its own cardboard box
- Clean as you go (scrape off gasket material, use acetone/cloth) to clean
- Follow both factory service manuals for breakdown/buildup

Based on the pictures below, it appears the spread spring in the 3rd-4th synchronizer broke and lodged itself in to prevent the sliding action between gears.

Excellent post and great you provided such step by step analysis. Only thing is and maybe it's because the pictures are uploading but on my iPhone I cannot see them. Hopefully it's because they're uploading because this is a fantastic post.

New Upgraded Transmission Assembly (SpecV Guts in Maxima Bellhousing)
Cleaned Maxima Bellhousing (Used acetone and cloth)
Cleaned Differential Side of Bellhousing
Maxima Final Drive and HLSD from SpecV
SpecV Reverse Gear Set
SpecV Gear Stacks and Maxima Final Drive in Bellhousing
Maxima Final Drive Meshed with SpecV Mainshaft
SpecV Mainshaft Meshed with SpecV Input Shaft
SpecV Input Shaft Meshed with SpecV Reverse Gear Set
Detail SpecV Main and Input Shaft
SpecV 5th/6th Shifter Fork with Maxima 5th/6th Shifter Fork Rod Detail
The SpecV 5th/6th Shifter Fork Rod had a pretty significant burr on it, and wouldn’t actuate properly. So I used the Maxima version.

Great thread. Thanks for all the pics. I'm obviously a little late to the party just finding this now......curious on this:
Is there any reason why you went with a sentra gearbox instead of a 6th gen gearbox? It's my understanding they have the same gear ratios, both have hlsd, and the same final drive ratio (4.133)...... but the 6th gen can be dropped straight into a 5.5 gen without modification. Perhaps I'm mistaken on that?

^This.
Sentra trans runs around $300 and are plentiful, A +04 6spd maxima trans...... Internally they are the same transmission the only difference is the bellhousing is different because VQ vs QR.

I uploaded all of my pictures that were above in that link. Maybe someday I can resort the thread so the pictures are in the right place.

Anyone know of a cheap bearing puller for these trans? Im trying to get all the special tools I need for the job.
Looking for a consumer version of this I suppose: J39856-Kent-Moore-Gear-and-Bearing-Removal-Kit-

I did all of the measuring but did not have to reshim it. The existing shims were good. I needed no special tools whatsoever I also had no prior experience rebuilding transmissions. I simply followed the fsm.

Wow, that's very impressive! I'm considering doing something similar with a 6 speed, but am unsure if I can tackle the job myself. I got a quote from a local trans shop and they estimated it would cost $600-$1000 in labor, and for that amount I'm wondering if I can do it myself. So the FSM is really that detailed? How has the transmission help up since you installed it?

I'm very green in this area as well and thank you much 6spd_Hayes for the thread this helped me greatly! I'm running into issue though how are you removing the shift forks to remove the gear set? I'm doing a similar swap 5spd for 6spd using the spec v 6spd. Also where can I locate the fsm?
