4l60e question

[Dspurlo81]

I have a 4l60e with 35k on a rebuild. When I left work it shifted just fine for about 2 miles then it lost every gear. I pulled over and let it sit for a minute then I started it up again and it had every gear so I drive for another 2 miles and it lost every gear again. So I repeated that a few times until I called a wrecker. Any suggestions?

even if you loose power to a transmission you will have A gear (so its NOT a solinoid ),so you have a real good problem ,no i cant tell you what it is, ,,,garage time ,sorry
