Shift solenoid?
Shift solenoid? I posted before about my 4L60E that lost 2nd gear. Here's the original thread:

Here's what's happening. When I go from a stop, it won't shift into 2nd. If I let up on the throttle, it will shift up into 3rd. If I'm cruising at less than 60 mph and go WOT, it "downshifts" out of OD/3rd and tries to hit 2nd, but just bounces off the rev limiter. The rest of the time, the trans is fine.
I drove it like his for about a month and a half now. Last week, while I was driving, it decided to shift into 2nd from a stop. It was a slow, weak shift, but it went into 2nd. For about half an hour after that, the trans worked fine, like normal. The 1-2 shift was strong, crisp and fast like they should have been. Then it had another slow weak 1-2 shift from a stop. After that, it was back to no 2nd at all. It has done this a couple times now. It always has a weak shift, then works fine, then another weak shift, then no 2nd.
Does this sound like a bad 1-2 solenoid?

I would say that is a 1-2 solenoid.......I just had to replace both solenoids in my 2000 S-10, wouldnt downshift into 1 coming to a stop. Plus I see a lot of solenoids being replaced on 4L60E's, must be crap parts.
Solenoids can be replaced in 10seconds with a flathead screwdriver. There right at the edge of a valve body. All you have to do it drop the pan. Just follow the passage lines to see the clips at the end. One clip is holding each of the 2 solenoids. This is from memory so sorry if missed something.
