okay so last week my speedo started jumping around an put my truck into limp mode. threw the speed sensor code. anyways I recently just put a new half case because of pump rub an had been fine for 6 months. so I go under my truck an messed with a few wires an the truck was fine for 2 days. now the speedo doesnt move an it wont let me go over 5mph woth out saying shift range inhibited. so I bought a new rear case an a bearing & seal kit from MA an a new sensor and its still doing the same thing. my question is where do I start to check wires like where are the grounds exactly? sorry its a long read
