Hello Buster. I checked the pins and the whole area for corrosion. I didn't find anything. Everything looks good. Also, is that an alright ohms reading that I gave for the speed sensor? Could it be working but giving bad info? I don't know what the reading should be so I was just asking. But everthing on the pins did look clean. Again, any help or answers that you can give is greatly appreciated. Thanks.

The resistance of the speed sensor is typical for that type of device. Further, if the PCM did not receive a correct signal from the speed sensor DTC P0722 should be set along with the CEL being illuminated. Additionally, the speed sensor is not involved in selecting Winter Mode which is not working as expected.

Since the wiring from the PCM to the solenoids is OK and the solenoids are new, it is possible the PCM is defective. To see if the PCM is properly controlling the shift solenoids you could hook up a Red and a Green 12 Vdc LED in parallel with each solenoid. When the PCM energizes the solenoid the LED will also illuminate. If you use Red for shift A and Green for shift B you can tell what the PCM is commanding. The alternative is too obtain a scan tool that can monitor the shift solenoids.

Thanks Buster. 12 vdc LED. Where could I get them and also how should I hook them up? I'm not familiar with it. Sorry for so many questions. But thank you for answering them.

You can get the LED's at Amazon. The LED has a positive and negative lead. The positive of each LED is connected to E-22 Pin 43. The Green negative to E-21 Pin 5 (Shift A) and the Red negative to E-22 Pin 31 (Shift B). Basically, your substituting a LED in place of the ohm meter. Ideally you would want to splice wires to the vehicle harness wires and run them to the LED's located where you can see them.

The PCM energizes the solenoid by grounding the control which is why the positives are connected to E-22 Pin 43 which is +12 Vdc supply.

hey rideforlifevegas I talk to buster he is a really good help and looks like is the transmission not electric like we was thinking he say is probably one of the couch to be exact is maybe the second cluch and the reason for that at least on my case was cause I have to drive it with very low ATF on it! if you can work on transmission there is an other conversation he got about this and he share a video where they show how to do it you self. am not that good about that so I will take it to a shop and I will post what happens when I get it back good look!
