MERCMAN, Thanks for your input. I will monitor the outputs of the TSS and VSS with my Autotap while driving the vehicle to try to determine if there seems to be a discrepancy with their readings. I will also monitor the fluid temperature during exended freeway driving to determine if the trans fluid temperature is excessive. During normal highway driving (55 MPH) the trans fluid temperature seems to top out at the engine coolant temperature (198-201 degrees). Keep in mind that the temperature here at the time of the test was 94 degrees.
