42rle rebuilt 3k miles ago ... could be normal but it take a bit longer for the trans to shift into overdrive than the other gears ... was the same before the rebuild so guessing it's normal but never had another vehicle delay shift into any gear..it's like the shift is in slow motion or something . Then after being in overdrive for a minute or an hour if not on the gas the rpms will go past where it should be then resettle a second or two later when accelerating like it's slipping ... got 125k miles from purchase before losing overdrive and forcing the rebuild... she's currently at 434k miles however it does shift exactly the same before having issues . I guess what I'm asking is .. is there a way to speed up or make more solid , the shift to overdrive or is it totally normal ... rebuild came with 15 months or 15k miles warranty ... will also be adding a trans cooler in the next couple weeks ... before it gets hot
