My 06 Silverado 1500, 5.3, 4l65e, 4x4, 145k miles, started shifting into second very softly the day before yesterday. Until then it had always been a very firm 1-2 shift, especially at low throttle. The fluid isn't perfectly clean, however it is not burned, does not smell burned, and there's no metal in it.
If I manually put the shift lever in "2" to start, and stab the throttle it will slip. I did this once. When driving very nicely it will still be a positive shift I can feel from 1-2, the same for putting it in "1" and letting it shift itself. But under normal driving conditions, I can still feel it, but it just slides into second.
All other gears work correctly, or at least seem to. OD works perfectly as far as I can tell, with no hunting in and out of gear, the TCC stays locked up perfectly. Could this just be a problem in the valve body? Or are the clutches for second toast? It seems weird to just happen, it does not seem to have gotten worse.
Would it be worth it to do a fluid and filter change, or is that just throwing money away at this point? I'm dreading this. I had nothing but problems with 700r4s, and I'm not going through that nightmare again. Nothing would last, rebuilds, used ones, the best one was one that a friend and I rebuilt when we were 19.
