This video shows you how to replace the transmission shift solenoid (solenoid pack) in a 2010 dodge ram 1500.
My truck was giving me a random check engine light every so often stating that the gear four had an incorrect ratio. After research I found the shift solenoid could be the issue.
Tools needed:
1) ramps (i had two sets)
2) 8 mm socket
3) 19 mm socket
4) 1/2 " ratchet
5) 1/4 " ratchet
6) wire brush
7) drill
8) flat head screw driver
9) filter wrench
