Only first gear works, codes p0732 and p0700

Hello,

It sounds like one of two things could be happening first the input shaft speed sensor can be off causing the codes or you have a TCM that is out. I would first try removing the electrical connectors from the TCM and check for corrosion on the terminals.

Here is the location of the sensor and the TCM so you can see whats going on.

Check out the diagrams (below). Please let us know what happens.

Cheers, Ken

I forgot to add that it is the R/T 3.5L, but I think it is the same in that diagram. Just got it onto the jack stands to check out what you advised and a thunderstorm began rolling in. I am shade-tree for real. Lol! Will let you know how it goes when I get to it. Thanks!

Lol, yep a little tough in the rain. Please let me know. :)

I just crawled out from under her and all the connectors look new on the inside. I am not sure if it matters, but with the front end jacked up, the second gear noise seems louder. Perhaps being further from the ground has that effect. what do you think Mr Ken?

Can you please shoot a quick video with your phone so we can hear the noise? That would be great. You can upload it here with your response. That way I can tell you if it is an issue or not. Also, did you try the speed sensor?

I have not changed the sensors. How can you tell if they are bad? I will get you that video ASAP.

Here is the video:

Great work on the video. :) I do not think a turbine sensor is the problem it looks more like the TCM has gone bad, but to be sure lets run the codes and check for power and ground at the TCM. Here are three guides to help us run some tests and the TCM wiring diagrams and the location (above):

Confirm power and ground at the TCM check fuses and the transmission control relay.

Remove the electrical, connector to check for corrosion and the TCM as well. Check out the diagrams (below). Please run some tests and get back to us.

Wow, this is great information! I will start working on it tomorrow if I have time. I was talking to my above stated loved one (aka Pawpaw), and he said that it started running hot and had a shop replace the thermostat. The mechanic had a hard time purging it, but did it "successfully". On the way home from the shop is when this problem began. I am going to see if the mechanic may have disturbed a pertinent wire around the thermostat. What is your thoughts on this? I will let you know what I find. Thanks!

Yes, double check his work then use the wiring diagrams and guide to troubleshoot the problem.

I have pictures of some things and a description, but I cannot upload the pictures. It says invalid file type.

Okay, I did some digging around and came up with a few possible issues. I hope you can read my handwriting in my diagram. That diagram is a connector that comes off the TCM bottom connector, but not directly. Once it gets to the firewall, it splits and this one goes down to the transmission. The two that do not have description and show no voltage are the two speed sensors. I read the diagram and saw that the black/light blue ties in with several other things. The engine temperature sensor happens to be one. The next two pictures are of a component on the intake manifold, just above the thermostat. The last picture is of the plug and wires that go to it. I have no idea what that component is, but I think it is shorting out, and causing my problem. What are your thoughts?

Finally! Here is the above mentioned diagram that I drew:

The wiring connector in the picture you can see one of the terminals has pulled out? Can you check that for me. Also, what color wires go to the part in question? This sure sounds like a speed sensor is not working.

So far I cannot recognize the wire colors. I am going to have to cut back a good ways because they are burned. Yes that connector is loose and the wire will pull out of the back. It was secured when I pulled it off though. I tested the speed sensors as described in the link you provided and they were not getting juice. They checked out good on the wire test also. However, I could not get my hands in a good enough spot to unravel the ground splice I spoke of. I still could not get power by grounding elsewhere.

I think we are getting side tracked here. It still sounds like the TCM is bad because it acts different in the autostick mode. If you have tested all the wiring power and grounds it only leaves the TCM.

My life story! Do you think these wires shorting out could have fried the TCM? I am going as far as I can on the harness without removing too much so I can at least tape them up so they do not touch.

Yes, bare wires can create all kinds of problems. Tape the wires up and let's find a used TCM to see what happens.

I am having, some trouble. Which of these two "boxes" is the TCM?

It should be the one in front of the PCM check out the diagrams above shows the location. Upload a picture if you have questions

This is mine. Do these numbers have to match exactly?

They do not have to match, see if the color wires going into it are the same that are in the wiring diagrams earlier in the post.

I ordered one that has the same numbers online, cannot see the wires on them. I will have it in a few days.

Wish us luck! let me know.

Alright, computer did not work, got another last night (cheap on eBay). Input and output sensors should be in tomorrow. I the morning I will try the second computer. If this and the sensors do not work, what do I need to look into?

I would do a pin to pin check to make sure the wiring is in good shape. Use the guide and wiring diagrams in the earlier post.

Is this bad? It does not look good, lol.

Those are some big metal pieces on there. The transmission could be coming apart inside.

That is what I was afraid of. Seems like the magnet was holding all that it could and there may be more than that inside.

Yep, might be time for a rebuilt unit. Here are diagrams to help you get the unit out for the rebuilder or a used unit. This is a video of a front wheel drive transmission being removed (different car but the process is the same) with diagrams below to help you see what it like for your car.

Check out the diagrams (below). Please let us know what you find.

Thanks! I will post my progress, I am not going to get rid of this car. It has sentimental value, lol.

Yep i hear that, fix it because we can :) let em know
