Vehicle 'Popped Out' of 4x4 in reverse and I lost all of reverse and over drive. Will still shift into 3rd either at 5k RPM @ 40mph or if throttle was released @ 17mph it will shift. Code # P0752 was only code shown but never had any warning lights displayed.
When this code is googled not much is directly associated to exact problem. -
'Popping Out'-- this is on a 02' GMC Envoy XLT -- it makes a wining sound in park and gets a bit louder when in reverse , neutral

If the fluid level is OK, then whining noise indicates that there is a mechanical problem with the transmission. I suggest having a transmission shop inspect the transmission for you.

After pulling the pan to change the filter and fluid, I seen a lot of shiny silver glitter. Not good !! The problem is deffinatly not the fluid or filter, it's much deeper. I found a couple of 100k used transmissions for $400 so my time n knuckles I'm go'n that route.

If you already have new solenoids, then the next step is to check the wires from the solenoid to the Powertrain Control Module (PCM)
