Leaking of oil is observed mostly around the extension housing Automatic Transmission Output Shaft Seal and since this can be replaced easily without having to uninstall the transaxle from the car. The extension housing Automatic Transmission Output Shaft Seal is sited at the very end of the transverse part of the body of the transmission where shaft drives are fixed. To start off, lift the car and place it on jackstands properly so that all the wheels are off the ground. If the seal is leaking, Transmission lubricant will leak on the front of the drive shaft and may drop from the rear end of the transmission. Next, remove the driveshaft. With the help of a puller or a seal remover tool, it might be removed from the rear part of the transmission, being cautious not to harm the spirals on the end of the transmission output shaft. For fitting the new Automatic Transmission Output Shaft Seal, get a piece of pipe or a very large deep socket as a driver which should be struck into the bore square and to its full depth. Apply thin Sleek grease to the splines of the transmission output shaft and the external circumferences of the driveshaft slip yoke, before reinserting the driveshaft, it will be important not to scratch the new lip of the seal that comes with the new driveshaft. Last of all, check the conditioner level in the transmission and refill as is proper.
