E4OD code 622
Original tranny lost Drive, Bought a used and installed, It goes real high rpm in 1st gear before shifting directly into overdrive and shuttering from low rpm. Gives a code 622 shift solenoid 2 failure. Is this something electrical I can try to repair or an internal transmission issue?

Codes do NOT identify parts - they identify CIRCUITS and signals that are out of the expected range.

Then use any decent digital multimeter (DMM) to measure resistance (Ohms) between the SS2 terminal and the VPWR terminal of the EEC connector (EEC unplugged):

Do not damage the wire or terminal during testing - use the appropriate meter probe to make contact with the circuit.
