AX-15 options or replacement

Hey all,

I have been having some issues with my AX-15 on my 98 TJ, only 88k. I believe it is the throw out bearing that is whining which might have been caused by a slow leak I found and it was too late by then. Also, drained the fluid in the tranny and found some metal filings in not good. I am not really sure what caused this so I am gonna take it to a local guy to look at before I do anything. My question is if you all have some knowledge on some options for me. I was searching the web and on here and am just getting some ideas. It seems another AX-15 would be the best bet but I am not sure what years...97-06? I also read about another option of an NV3550 but I am not sure if that will bolt up to my bellhousing and transfer case. I am also gonna look at what was actually damaged in the tranny to see if it might be easier just to have the damaged parts replaced instead of buying a whole new tranny. I really would like to stick with a manual for what its worth. Hope you guys can help!

I am looking to have my 97 TJ trany rebuild also. it is an automatic and my 2nd gear band is shot.
got a quote of around 975.00 to do it.
Mine has 93,000miles.
Looking to see if this price is in line with a rebuild
Also concerned about having to have this done at 93,000 miles.
All maintenance is regular and just changed the fluid and it looked great.
It is what it is but curious if this is common or not.
2007 Rubicon Unlimited, stock w/MyGig.

RIP 97 2.5L TJ/2BB/Pacesetter Headers/Cold Air Intake/32in ProComp Mud Terrains/6in smitty flares/DynoMax exhaust.

the folks at rockland standard gear ( say the ax-15 is FAR superior to the nv3550 which has had shifting and parts availability issues since jeep replaced the ax-15. I also think the nv is not a direct replacement. You can buy a new ax-15 from them for 995 with your core, others on e-bay sell them rebuilt from 645. RSG has a highly modified , bolt -in ax-15 that uses parts from a supra turbo and can handle 485ft/lbs. for1695 (overkill for a stock jeep). just some info...
