I try to be here most weekdays and some weekends. If you respond and I do not respond back right away I will do so as soon as I can.
Dear customer,i understand the problem present what you are presenting in the transmission is known as a transmission bump or kick usually due to oil pressure problems. As you aalready replaced the transmission fluid, the problem may be on the oil pressure control valve so it has that error code.
The oil pressure valve is the valve in charge of supplying the information to the valve body to know at what moment to perform each gear according to the pressure exerted within the transmission, when it is defective, the transmission does not know at what pressure to perform the changes. Therefore, when putting first gear, it kicks abruptly due to ignorance of the pressure in which the transmission is.
You will need to first check the condition of the transmission pressure sensor.
The other possible cause is that the first selenoid is getting stuck or has problems, as is the pressure sensor, and the first-gear solenoid or solenoid valve, when damaged, applies gears abruptly.
Lastly, dear customer, I recommend you also check the transmission mounts/supports. The bases are the supports that hold the transmission to the vehicle chassis. These supports are made of rubber. These rubbers eventually become damaged, which causes the transmission to move more. Abruptly, in any case, you are already presenting error codes regarding the transmission, therefore it is very likely that the defect is in the transmission interval as explained above.
Have you understood me dear customer?
