OSS replace

Question

I have replace my oss and it is still doing the same thing. I have looked at the wiring harness and I don't see no breaks

Answer 1

P0721 and P0722  these are the only code that would set for a OSS fault, A good way to test  is with a factory level scan tool,  The vehicle speed sensor and the OSS sensor at a test drive should match the same. This type of transmission are known for a harsh shift and delayed shift and a transmission flares without setting a code, If this is the case you need to check the transmission fluid condition, by draining the fluid and inspecting for excessive contamination or material. If good you replace the valve body and reflash the TCM
