I was going through the 68rfe programing and have 2 question.


First: There is a graph for each of the following, normal, T/H, DSM,CRUISE. What is the DSM stand for? got the other three.

Second: Looks like the rpm on the graph are output shaft rpm not engine. is this correct.

Is it Driver Select Mode?

Yes correct, Driver Select Mode.
A bit tricky because the trans code is shared between the gas vehicles as well, so each mode might actually be used differently on different platforms.
