When I slow down I feel a clunking noise and then it will not go back into fourth gear

Most of the codes are saying that there is low voltage. How do I know it's electric, and not the transmission? I changed the transmission fluid and filter and it still does it. How can I determine what the issue is?

Good morning,

Can you list the codes for me so I can see where I can help narrow the area of failure?

Okay, the 736 is the key. That is a ratio error which means it is slipping internally.

That will require removal of the transmission and either a rebuild or replacement

Is there any way around rebuilding the transmission? Do you think that there is a bad connection or a short in the wiring?

No, not for the gear ratio code. You can continue to drive it for now but it will get worse over time until you are restricted to one forward gear only.
