I put a new transmission in 2 weeks ago. It works great however, after driving the first day my spedometer and odometer quit working. oh well. I have been getting some codes so I checked them. This is what I am getting 13, 23, 24, 32, 43, and 44.
Wow whwere do I start? Is my O2 sensor done? What should I fix first?

thanks in advance,
Jamie

 

Check your grounds at the back of the cylinder heads.

Other than that, just make sure all your wires are still connected.
