anyone ever tear into a t-5? i blew the tranny in my dd, and the only one i could find had a mechanical speedo and mine is electronic. im want to take the tailshafts off each and swap out the speedo gear for the sensor. is anything going to fall out or should i be good. How do i know if the rear main seal is bad without taking the clutch off. the entire motor and trany is covered with oil, so is inside the belhousing.
