Summary
Some customers may complain of a shift shock felt when shifting into 3rd, 5th and/or R range with no A/T related DTC stored. The symptom can be temporarily repaired by A/T initial learning procedure, but may recur after multiple driving cycles. Applicable situations: *Shifting up: 2-3, (4-5) *Shifting down: 4-3, (6-5) NOTE: (4-5) and (6-5) are felt more than others due to the gear ratio. *Shifting into R: D-R, N-R, P-R Improper control logic of the TCM may cause improper learning of R-3-5 brake engaging speed during certain driving situations. To correct this concern, the control logic of the TCM has been modified.
