Taking advantage of some decent weather and finally having the throwout bearing sleeve in hand, I decided to install the rebuilt transmission last evening. It went in without a hitch-probably because I've had to do this job three or four times for various reasons, and you can't beat an NOS input shaft for a good clutch-aligning tool. I still need to weld up and re-drill the upper clutch rod arm because the connecting hole is an oval shape from so much wear over the years. I'll probably order a new one down the road but need to try this first so I can complete the linkage installation and shake down the new transmission. I can also see that I'll need to drain the fresh GL90, pull both PTO covers and reseal them-nothing like an M-Series fresh rebuild that still wants to mark its territory....

More to follow,

Gary, Your truck isn't marking its territory, its sweating power.

Thanks Bert!
Well I had to sacrifice my winch money in order to replace the tranny so I want to be absolutely sure it will hold the GL- "life blood"....

Cal,

Make sure to clean the cover bolt threaded holes in the tranny casting and use a thread sealer on the bolts to prevent the gear oil from wicking and leaking from the bolt heads. If I recall they are tapped thru-holes.

Good point, David-yes I recall they are drilled through, and will seal them accordingly. This weekend was a smokeout-brush fires across the bay blew plumes of smoke thoughout Monterey County and it was difficult to breathe, so I stayed indoors and didn't get anything done.
