Shift Kit Problem 4l60e

[zz50]

Installed a 4L60E shift kit and now I have DTC issues along with trans not shifting. Codes P0740. P0753. P0758, P0785 and P01860. Trans has 2,3,4 and reverse but must be shifted manually from 2-3 and 4th has no lock up. No shift from 1-2. Has anyone seen this problem before? Truck is 03 Sierra with 4L60E. No issues before install. Anyone have the same issues after the install? All solenoids and force motor are plugged in and valves/springs are checked.

Sounds like your trucks PC needs to be updated with the new shift kit info. Didn’t the shop update or at least tell you to update your trucks PC?

Problem solved... Seems that the solenoids have power to them all the time and the terminals exposed causing ... you got it ... a short and blown fuse. Thanks for the time to look and reply... Shifts good
