Attention: TDR Forum Junkies 
06 QC 4x4 5.9l, 48RE. 200k miles.
Last week, I installed the Superior shift correction kit (K48RE) and the Superior Extreme Duty Servo kit with Band strut, etc. The shifts were firmer and more predictable for the first 50 miles. Then I parked it overnight in 15deg F temps, and the next day, it felt a little sluggish when shifting. 30 Miles down the road, and sluggish has turned to slipping a bit, and 10 miles later, sitting on the side of the road. No forward gears whatsoever, although reverse is fine. Towed to shop, dropped pan and the fluid is for sure burnt. It look like "clutch dust" in the pan as well. Fine black material?
From what I've read so far, the rear clutch pack has maybe failed? I'm not really an expert, but I can follow a good set of directions well. I don't think anything was screwed up on the install of the kits (I could be wrong). It is possible that the clutch pack was a time bomb waiting to go, and the shift kit was enough to push it over the edge?
Where do I go from here? Its my daily driver, but I only tow a small (7x14) enclosed trailer, maybe 8000 miles/yr., so I definitely don't abuse it, in that regard. I'd like to get another 200k out of it, but it has a fairly easy life. I can get a reman from O'Reillys pretty reasonable, or should I get a more built unit? Is there something else that I'm missing, like maybe it isn't the clutch pack?
I appreciate your advice and comments.
Thanks!
