So I just wanted to sort of update on my transmission woes. I finally gave the band adjustment a shot... 2007 SC 2WD 4.0 with 5R55S, almost 125KMI. The bracket holding the shift cable has two bolts that needed to be removed in order to move the bracket out of the way of the one adjusting bolt. I put the truck on ramps so E-brake was set and blocked the wheel just in case. Painted one corner of the 4 point adjusting bolt and adjusted them to 120in/lbs, backed them off two full turns. A while ago I read somewhere there was an updated TSB saying to only go 1.5 turns but I couldn't seem to find anything on it now, so I went the full two - I can always turn them in another half a turn if needed. Anyway, two turns out, locked them down with the lock nuts, reattached the bracket. The transmission is shifting much better than before. It is smoother, no flaring, no more of that annoying banging or bumping on downshifts. No hesitation, pauses or general feeling it is slipping for the first instant on upshifts. Everything is very smooth, crisp and noticeably different [better] than before the adjustment! I have almost 125KMI on the transmission. The past few times I changed fluid there was always a lot of gray gunk in the bottom. I wish I would have done this sooner, maybe at 75KMI or something. The one adjuster needed at least one full turn in, the other at least a half. Hopefully running out of adjustment hasn't caused excess band wear that I could have adjusted for miles ago. Cheers, Dan B.
