Hmmmmmmm.....kinda dissapointed in myself.  I just realized that despite covering every other important maintenance item in the 8 years of owning my GV (with minimal work done by con-artist dealerships), I forgot something kinda big.  It seems that I haven't had the manual transmission oil changed since 33,000 miles.  Not good, considering I now have about 150,000 miles on my little truck.  Yikes!  Guess I better take care of that immediately.  Any thoughts on how detrimental this might be going forward?  Please...don't be too harsh on me.  LOL    Trust me, I've already called myself a bunch of bad names since discovering this oversight!  I hope the stuff they put in at 33,000 miles had magic fairy dust in it, cause something tells me it's not good to go 120,000 miles between transmission fluid changes.   

If ya haven't had any problems so far.
Great, Change fluid NOW...
And your good to go.,..
A/T hold up well with D.D.

Betcha notice the tranny runs quieter and shifts smoother.  I drained both of Busters diffs and his tranny oil last night.  He's got 88K on him and I can tell a slight difference in shifting today.  I didn't get to the transfer case though (ran out of time and body heat).  I went with Castrol gear lube.  Suppose it's good stuff.  I've been running their oil in my engines for several years.

Speaking of 5 spd trannys on these trucklets, does anyone on the forum have any experience in taking these 5 spd cases on these apart to replace synchronizers, main bearings or gears?  Or has anyone HEARD of anyone doing this and if so any success?

   I have done it,and it is not that bad.I have read a couple of articles on this site about people doing the rebuild.

Kingzoo, what did you use to separate the housings?  I look at how tight the thing is and made of aluminum to boot and I'm thinking of ways and tools to use to separate them without gouging the metal.  What about pressing bearings... did you press your own or take them to a machine shop?

   We have a machine shop at work,so I have access to most everything needed.I allways use hard plastic seperators and wedges when working with aluminum.It is a habbit I got into when I first started working on firetrucks.Nothing like cracking or marring a small housing that cost about 4 grand.
