Dear Sir i have Nisazan zentra gear not change...

Thank you for contacting us 
Dear sir 
P0965 fault in the pressure control solenoid B
You have to check these items first 
1. Check the transmission fluid. 
2. Check the ttransmission fluid filter. 
Then 
You need a specialist in the automatic transmission that can do overhull for the gear and change the fault solenoid or change the body valve of the gear. 
The last option that you have to replace the gearbox with a second hand one from the scraps. 
Best regards
