8. Check the Transmission fluid and adjust if necessary. Refer to the Service Information for the
proper Fluid Fill procedure.
9. Perform the ADAPTION PROCEDURE whenever the TCM and/or the Transmission has
been replaced or major Transmission repairs have been performed. If none of these apply,
proceed to ROAD TEST PROCEDURE.

11. With the DRBIII
t
, reset the Transmission adaptives. Resetting the adaptives will set the
adaptives to factory settings.
12. Drive the Vehicle until the Transmission Temperature is in the specified range.
13. NOTE: Perform the Coast Down Adaptations first. The Transmission Temperature
must be greater than 60° C (140° F) and less than 70° C (158° F). Failure to stay within
these temperature ranges will void the procedure.
14. Perform 4 to 5 Coast Downs from 5th to 4th gear and then 4th to 3rd gear.
15. NOTE: For Upshift adaption, the Transmission temperature must be greater than
60° C (140° F) and less than 100° C (212° F). Failure to stay within these temperature
ranges will void this procedure.
16. From a stop, moderately accelerate the vehicle and obtain all forward gear ranges while
keeping the Engine RPM below 1800 RPM. Repeat this procedure 4 to 5 times.
17. Obtaining 5th gear may be difficult at 1800 RPM. Allow the transmission to shift into 5th
gear at a higher RPM then lower the RPM to 1800 and perform manual shifts between 4th and
5th gears using the shift lever.
18. The TCM will store the adaptives every 10 minutes. After completion of the Adaption
