Need guidance on 700r4 swapped transmission issues

[Richard]

700R4 uses a TV cable. Basically a throttle position sensor for the trans. If not adjusted properly it can lead to a short life. Good to learn new stuff, I have done trans rebuilds myself. TH350 and 4L60e. Everybody starts somewhere. Pump rebuild is pretty easy. Basically, the whole process is not bad. Just having/getting the knowledge and ability to know what needs to be replaced, what can be repaired and making sure everything goes where it should in the trans. In my honest opinion if you have the trans out and pump removed it would be a mistake to not go through the rest of it.
