I had this happen at 75 mph some 45 miles from home... got it working in low range... and then it kind of stayed... was able to continue another 20 miles further into the adventure and head back home... it acted up about a mile from the house... had to drive the last mile home in low range... if someone ran gear lube in this device, or ever engaged 4x4 without a front driveshaft, or with hubs disengaged it damaged it... I think mine failed because I had a 6.2 Diesel in front of it... another friend had his fail because someone used gear lube to fill the case. you can replace this with an NP219, NP228 or NP229 without having to change the driveshafts. If you try to use an NP208 you'll need a different shaft rear shaft I believe... the case on the 208 is noticeably thinner... so it must be the rear shaft. You might be able to find the viscous coupler at a transmission shop. Or via on-line parts... shop around though as this part could be very, very expensive and it may be cheaper to swap the entire xfr case. If you're up in the PNW I highly recommend Dave's Lynnwood Transmission Service, Dave Sr. would be your best bet, but Dave Jr. might be a good source as well. Olympic 4x4 may have a case or know of one... Crown Automotive parts distributer might have the part, as might BJ's Offroad. you can let Dave, BJs or Olympic know I sent you, might get a price break, or at the least a hard time. :) the 228/229 isn't a bad xfr case, but I don't like that it doesn't have a high lock feature like the 219. I do like the full time capability of it. In the XJ models the NP242 is a nice unit, has 4x2, 4x4 low-lock, 4x4-high-lock and 4x4-high "open" like your np229. rumour has it that the 228 has a center differential unit instead of a viscous coupler, however when looking at a variety of documentation, as in shop manuals, parts lists, etc. it's listed both ways... so if you can find a 228 you may get a center differential unit instead of a viscous coupler that lives in the 229 for certain. Then NP219 was used from 80-82 and does have a viscous coupler but I've had several without problems, and don't recall of hearing about any failing... I'm not sure if an XJ xfr case could be adapted... but they are almost all slip yoke setups which are NOT desireable... the rear seals leak and if you get broadsided by a Saab that submarines a bit it'll pull your rear driveshaft out and you will have to be towed home... don't ask me how I know about that problem... ;) I'm on my windoze box editing some fotos right now or I'd provide some links, they'll be in http://wagoneers.com/FSJ/tech look for the transfer case directories, also check JEEPS and XJ/tech. in the meantime, if it does fail you should be able to move about in low range... just try not to merge on the freeway like that or you might have a saab submarine story... john ----- - ------------------------------------------------------------------------ -o|||||o- fahrvergnugen y'all Snohomish, Washington - where Jeeps and VWs don't rust, they mold http://AMSOIL.com/redirect.cgi?zo=283461 http://JohnMeister.com HTTP://WAGONEERS.COM http://fotomeister.us - ------------------------------------------------------------------------ On Mon, 25 Jul 2011, geronimo-at-pipeline.com wrote: # Hello John, # # i sent an email via your website, and then i found your email on a page so i am sending as well to this address just in case # Maybe you guys can help me resolve a weird problem # # I ran into a problem on my GW 90 (transfer case NP229) that drove me nuts for the past days as I cant understand what is going on # # Feels like the transfercase is disengaging (like going in neutral) when I am in 2x4 high gear. # # How it happened # # I was driving when I had to brake very hard and while stopping I heard like a whistle , like pinions trying to get in gear, same as when going from high gear to low gear if the transfer case is still spinning till i can get in in gear.

You can deduct that I currently have 204kmiles on the original trany and TC. Fluid has been flushed twice on the trany, when purchased it was dark. I ran 6 or 7 quarts until the fluid was bright red, then ran the remainder of the carton 6 quarts. I did some HD towing one winter bringing another wagoneer to the ranch.... then redid a trany flush and filter change. We can either keep it private and pass the infos to the group.... let me know what you think?
