Guess I spoke too soon. I thought I'd saved my tranny, but one day I noticed that the torque converter clutch was no longer working. No biggie I thought, just a little loss of gas mileage aint worth a rebuild. Then one day I towed my buddy's boat for him (aprox. 4500lbs.). We had some pretty steep, long hills to clime & like a dumb*&# I put my foot to the floor to show how well the X pulls a load. A few minutes into it I notice a James Bond style smoke screen comming from under the truck, so I ease up on it. When I got home I went straight to the trans. dipstick where I found my just serviced fluid burnt as hell. The trans. was still working well so I thought I'd just change it again. The next morning I jump in to go get some trans. fluid & no upshift! After manually engaging 2nd & getting it up to 45 or so I put it back in D then it went back to norm. I've been driving it that way a couple weeks now. Every time it sits an hour or so, it won't up-shift till I force it, & occasionally sticks in 2nd when I come to a stop untill it warms up. I went ahead & seviced it hoping it would help, NOPE. I'd been considering selling it, now I may have my decider.
