AUTOMATIC TRANSMISSION OIL PRESSURE DATA TRANSFER –
GDS MOBILE (8-SPEED TRANSMISSION)
Description:
This bulletin provides a procedure to transfer oil pressure data to the TCU using GDS Mobile. This
procedure is necessary to reduce the TCU learning time and improve the shift quality.
 Before replacing an automatic transmission: Input the data into the TCU using the GDS.
 Before replacing a TCM: Back up the oil pressure data from the old TCU into the GDS and
then transfer the data to the new TCU.
NOTICE
Before installing a transmission, use the GDS to transfer the pressure characteristics to
the TCU. If not, take a photo of the new tag or record all digits on the new tag. The
barcode tag is difficult to read after installation.
The oil pressure characteristics barcode tag location is shown below.
