I've got a 91 suburban 3/4 ton 4x4 with a 4L80E trans that just in the last 3 days has started shifting in n out of 2nd/3rd. Does it a couple times then drops into od fine. I've never had an electronic trans, always 350, so I'm not sure where to start looking. It's shifted hard, to me, since I've had it, but dunno if that's normal or not. It is sitting on 35 inch ties with 6 inch lift as well, dunno if that's an issue or not. Thanks in advance for the help.
