I-shift trouble

Please help..
Volvo FM D13A I-shift air leaking from the solenoid control valve. i check all the gasket between the transmission ECU solenoid valve and the gear control housing, but the air from the hole under the solenoid valve (4 unit valve linked).

The truck dont run after shift the gear selector into drive position cause when i press the accelerator pedal seem like nothing.

can u please show me where is the shift rail and functioning for total 9 unit of the solenoid valve..

i replace another transmission ECU along with the solenoid valve from other good condition truck but air still leaking, it is possible gear control unit ,changing fork trouble??

both has no fault codes..

 

ya, i can see total 9 solenoid valve and the transmission ECU under the cover right, then can i ask u about function for each solenoid valve?

 

yup, i can read from impact.

i have check with the gearbox, everything ok, i found faulty clutch. how to measure for the clutch wear???

my company have a lot of volvo truck with i-shift and trouble with these transmission after few year, we are not familiar with this and result long downtime. we send to volvo dealer may need 3 week or more. can u please provide me some I-shift trouble-shoot and service manual
