Hyster H155FT:
Trans wont calibrate

Fault code 522800-13 "Transmission Valve Calibration"
I have tried the trans calibration procedure multiple times and it will start the procedure but skips over "Calibrate Xmsn Valve Xmsn Calibration 0" and goes to "Calibrate Xmsn Valve Xmsn Calibration 1" It never finishes Calib 1, just goes on and on and never completes or kicks out. Never says Failed-out of range etc. I have Hyster PC service tool and shows 522800-13 as inactive fault but wont clear, also wont clear out of display, as soon as you turn the key on shows code in screen. Cant find any incorrect/implausible data with pressure sensors etc.

Did you ever find what was stopping the calibration?

Once the transmission is up to temp, it "should" start to calibrate the valves. You have to keep the parking brake on and your foot on the brake pedal the entire calibration. If you take your foot off, it starts over.
