International works but doesn't go 

brought Internacional to St. Petersburg and said? figure it out, everything is ok with it, but it doesn’t drive, the gearbox is astronic (IVECO). The car drove and drove and stopped 600 km after the transmission was rebuilt - everything is new!
The display shows error SID58 and the frequent SM error also lights up.
Everything seems to be clear, there is a problem with the box, the box is not calibrated... why is not clear. The diagnostics of the truck did not show anything specific. well there's a mistake in the box...
Stock? or maybe robots or PSU? there are a lot of options, so we looked into it, it was interesting and unexpected to discover the reason, of course, in the end we had to remove the box to check the mechanics,
