Hello Alfonsas. Nice to hear from you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Has anything been done to try and locate or resolve the code issues yet?

added grease to the gearbox. the code disappeared, later reappeared. now the code is gone. where are the problems

Thank you for your reply and that information as this does help me better understand the situation. Please give me one moment to type out some info for you. I’ll be right back! Thank you for holding Alfonsas! The codes coming up indicate an issue with either the 1-2/4-5 shift solenoid failing inside the transmission, a wiring issue leading to the solenoid from the transmission computer to the solenoid itself or a fault with the transmission computer internally to where it has to be replaced. In order to determine the cause, the wiring has to be inspected for any issues. If a wiring fault is found it will need to be repaired. If the wiring is o.k. then the solenoid has to be tested to identify if it needs to be replaced. If the solenoid has to be replaced this can cost over $300 to have it replaced. If the solenoid is o.k. then the transmission computer would need to be replaced and programmed by a dealer and this can cost over $700 to have performed in some cases. Below in the link is the testing procedure that has to be followed to pinpoint the issue. If you do not have the tools to do this testing yourself then a shop will need to perform this for you.
