Help!!!!! P0700 and P0722
This morning the brake light, anti-lock light and SES light all came on. I think it is stuck in 2nd gear when it will move otherwise it just flashes the shift indicator and won't move. Any ideas what it can be?

Sounds like a output speed sensor, or a harness problem. The p0700 is a MIL request by the TCM and the p0722 is for the output speed sensor.

That is the speed sensor on the transfer case? I have a spare from my old one. Anything else to look for while I am under there?

Thats correct. Also check to make sure your harness hasn't rubbed through anywhere, and there is no damage to the connector

I just changed the sensor and it is just the same. The plug looked ok. Is there any places to look at the wires that would be likely broken?

I found the problem. The wires come from the speed sensor and go into a larger bundle. Another small one goes into the large bundle at the same place. I pulled on those wires and I got about a foot of wire with two ends sticking out.

Butt splices will work just fine. Just mke sure to seal them off good.

Use seom nice shrinkable butt splices. If you dont have them then put some heat shrink tube over a regular butt splice.

I ended up just soldering them. I was able to get off to the side a little.
