FYI, you can't read gearbox code through the obd port! They have their own port and it requires a dedicated and much complex software to read them. The obd is only for emission related issues. The symptoms u r having sound Like the bands are slipping inside the box. Like I said take it to a place where they are capable of reading the gb module and see what can be done from there
