I have a 74 C4. When I was changing the transmission fluid this piece was floating freely in the driver side front corner of the pan, and it fell out. Does anyone know what it is? Btw, we were changing the filter to try and remedy it not shifting. The actual shifter works, but the transmission never kicks out of first gear when it's in drive. Manual 1 and 2 are both also still in 1st gear ...
