Trans will not shift out of first gear?

[DetailsUnlimited]

Refreshed trans and all went well. Drove for awhile after and did a few run throughs. Then went to store to pick up a few things and back. This morning went to drive and now will notl shift out of 1st. What is my next step to finding out why?

Start checking solenoids and speed sensors. I'd check for stuck valve. All those things should allways code but you never know. Wheel speed sensors can do it as well.

X2 , check the Engine speed sensor ( bell housing ) and Turbine speed sensor ( main case ) If you forgot to plug them in or the came out it wont shift out of first gear .

All plugs checked and good. Still no codes. 1st and reverse still. Will solenoids and stuck valve tommorrow. Thx for the help. Will post what I find.

Look at the pins in the sun connector for the output speed sensor. They can bend.

Tech2 is not reading any pressure on solenoid B. Pulled pan and VB and removed solenoid cleaned reinstalled and still no good. Will order new one and replace.
