Transmission stuck in high gear

[VinceWeiss]

I just put a new valve body in my 2006 Silverado with new accumulator pistons and solenoid’s and now that I have it all put together I went to drive it and it seems like it is stuck in a high gear like second or third and it has reverse has anyone had this issue before, is there some thing to reset like a transmission module?

There is no transmission module on a 4L60e.

 

I'm not an expert on that specific repair but obviously something didn't go right. What made you want to replace the valve body?

I just took the truck on a better road test, all gears are working other than 1st, if you put it in drive it starts in 3rd, and you can manually shift it into 2nd but not 1st. I saw on some other forums it could be solenoid A is that right?

I replaced it because my torque converter wasn’t locking, and so far from my test drive afterwards overdrive is good now just no 1st gear...
