I removed my transmission to replace the rear main engine seal and after I put it back in when I turn the key on the drive light on the dash immediately goes on before I shift the shift lever into gear. The speed sensor is relatively new and I put a different neutral park sensor in and re wired several connectors. What are the two sensors on top of the transmission and what is the function of the cable that comes out of the transmission. I also changed the shift cable and lever assembly. I also tried to reset by taking the negative terminal off of the battery for 12 hours to no avail.
