Let me share, my car TCU (transmission control module) kong and I am practically stuck on gear...was outstation at the same time, it's was absolute panic - had to drive 200 km stop start before I reach nearest RNR for towing, due to stipulated distance

Checked with SC - the cost blew me sideway - rm2500 not inclusive of labor for new TCU. Then I surveyed around and found a specialist who advertised ECU repair. Again arrange for tow truck to sent to sg buloh - total repair rm1.5k - with 6 months warranty, whereas new TCU replacement at SC - 1 month warranty.. just sharing, maybe your SC give longer warranty..
