Hello my name is tyler my wife has a 2007 escalade with the 6.2. She was driving to work the other day and the transmission did not want to shift out of first. When it did finally shift it slammed out of first that was the hardest shift then hard shift from 2nd to 3rd, then after those gears it shifted fine in the other gears, pulled codes and got p0776 pressure Silonoid b, p2714 Silonoid d, p0700 and a tps code p0121, is the valve body bad or a stuck Silonoid or is this signs of the transmission going bad thanks

For the 776 code it can be either the trans failing or the solenoid pack because it was stuck on if fluid is dirty like dark brown or black then the trans is probably time for a rebuild and a trans guy should really give an opinion on this one. With the 2714 the same thing what has happened is you had a cople of clutch paks on when they shouldn't have been so it can be an electrical problem. The other code may have set because of what happened.
