BA BTR trans coding

Recommended Posts

Can anybody please tell me if PCM can recode a new trans into a BA falcon with a BTR . 

We have fitted a new gearbox and it’s stuck in one gear with solenoid fault codes 

A replacement BTR doesn't need to be coded.

As long as the BTR is from a BA-FG, your speed source is correct ie if the original box used a speed transducer, the replacement must use one too & there's no issues with wiring or PCM, they are install & drive.  Earlier pre BA BTR's, the internal wiring is reverse polarity.

Did you have exactly the same issue & fault codes before replacing the gearbox?
It helps if you include fault codes when asking for help with diagnosing a problem eg P0753, P0758, P0763 etc. 

Check wiring & solenoids. It's not uncommon for broken wiring in BA's in particular at the C20 connector, occasionally near the ABS module, PCM & trans connectors.
Keep in mind that BA PCM's are failing at a fair rate now & it's not uncommon for them to put the BTR into limp mode & display fault codes for all solenoids.

Example broken wires at C20 connector.

ive had time to have another look at this and discovered there are actually no pins in the ECU for the C plug . 

Im assuming this may have something to do with the lack of auto functions ? 

Any ideas 

BA na PCM's don't have any pins in the C connector.

What fault codes do you have?
