I have a jeep. A 1995 YJ wrangler with a 4.0L a swapped in NV3550 out of a TJ rubicon, and factory air conditioning (no releveance here, I just like bragging since I have owned it since new). After years of hard abuse my original Ax15 lunched a main gear shaft and was completely undriveable in anything below 3rd gear and I swapped in a 30,000 mile NV3550 from a TJ that had been in a fire. The tranny was always questionable because of the fire but it has held up for years without issue. However, lately there has been the slightest crunch going into third gear and I noticed the other day I can grab it and snatch it out of gear even when on a load. I think the synchro is shot. This is actually common with the NV3550 - they were the 3/4 ton truck tranny (NV4500) guts shoved into a jeep specific aluminum case.
As this is my daily driver, and I have owned the truck since it was new I try to keep the costs and time off the road to a minimum while still trying to do everything myself. I swapped the tranny in so it is no biggie for me to pull it.
costs for a rebuild kit is between $300-$400, tools are $150. A reman tranny is $850 with a one year warranty. A new one is about $1500. From what I am reading online I should just suck it up and put in Redline MTL fluid and live with it until the tranny has "real" problems like broken shift forks or blown 1st and 2nd gear sycnhros.
so what do you guys think? am I kidding myself here? or go for it?
