A shifting problem occurred recently with my car listed above, I was told that the issue is my transmission speed sensors because the speedometer cuts to zero randomly as well as shifting to lower and higher gears when trying to maintain a constant speed. I ordered the two transmission speed sensors (input, output) but am having trouble finding the current location of the old sensors. If anyone has a blueprint or access the images that could point me in the right direction this would help me a lot. Thanks

Both speed sensors are on the front of the transmission, just about directly under the battery tray. To get to them you remove the battery, then the battery tray, as well as the air intake duct and air cleaner. Now you have room to work. Then you remove the bolt for the sensor, rotate and pull the sensors out and then lube the new one, put it in position and torque the bolt to 7-8 lb ft or hand tight.
