Here is a strong diagnostic article for you. Because this plate can fail in atsf a way where it will produces speed sensor or solenoid codes, there has been at times confusion with diagnosing the N2 and N3 wtsg sensors.
Unaware, the vehicle is started with a dry transmission sump. As a side note, the N2 rpm reading in 1st and 5th gear will not be actual input shaft rpm. This drum has the front planetary sun gear attached to it and it lugs into the B1 clutch on the pump. Sections of this page. This transmission does not have an output speed sensor.

Interestingly enough, the advertised gear ratios for this vehicle are as follows: But it will definitely ensure that the new TCM you put in will not get loaded with fluid 722. The next interesting aspect to this equation is the Output Speed.
