What steps are involved in replacing the Manual Transmission Extension Housing Seal and preventing oil leaks on Mazda MX-5 Miata?

Oil spillages can be caused by wearage of the Manual Transmission Extension Housing Seal or the speedometer drive gear O-ring, and replacing the seals is fairly simple, the transmission is not necessarily removed to replace them. The rear of the transmission has a housing that houses the oil seal that is attached to the driveshaft. To ensure that there is no leakage, raise the vehicle up on jackstands; in the case that the seal is leaking, the transmission lubricant will pool on the front side of the driveshaft and possibly drip out the back of the transmission. Start by taking off the driveshaft and then using a screwdriver or pry bar to carefully pop the oil seal out of the rear of the transmission making sure to not break the splines of the transmission output shaft. A special oil seal removal tool can be required in case the seal is hard to take away. To install, a large cross section of pipe or a deep socket is used to install the new oil seal, and it is important to make sure it is driven in firmly and to a complete fit. Apply lightweight grease to the splines of the transmission output shaft and around the outer portion of the driveshaft sleeve yoke and reinstall the driveshaft careful not to overstep the lip of the new seal. In models that are 1997 and below, the speedometer cable driven gear housing is at the end of the side of the extension housing; look around the cable housing to detect the presence of transmission oil. Unplug the speedometer cable and take out the driven gear housing, then put in a new O-ring in the driven gear housing then put the driven gear housing and the cable back on the extension housing.
