H3 2006 hummer h3 shift solenoid p0787

[austin316]

Hi guys, I recently made an transmission oil change and replaced the shift solenoids, for some reason the truck drives but don't shift.
Reverse 1,2,3 works.

I was getting the code p0787 before and is still there even after replacing them.

I went to autoparts to buy the solenoids, They told me that the Hummer H3 uses 2 of the same.
For some reason the old ones have different marked numbers and I was reading that they are supposed to be different, Solenoid A and Solenoid B, is it true?
Any suggestions on what Im doing wrong?

If you look at the bottom of that parts there are two lines on one and three on the other. Also Did u compare the parts when you pulled them? Did u get a parts at a knowledgeable place

I have replaced them on several 4L60's and they have always had the same parts number.
