My van has developed a leak over the last 3 weeks. It started with leaving a small spot on the garage floor and in two weeks it became much larger. I thought it was the pan gasket as I had changed the filter 17k miles ago. The rear bolts were slightly loose and I gave them about 1/4 turn. I cleaned the oil from the pan and the area around it. After a round trip of about 35 miles I checked it again and the pan was dry. The oil seems to be coming from the input shaft or torque converter area. If it is a shaft seal that has split, this is something that I do not have the equipment to do myself and may have to find a trans shop to make the repair.

Is there something else in this area that might leak that I can repair without removing the trans and engine?

 

The leak was from the oil cooler to the trans.

I have removed the hose from the trans 3 times when I have pumped the oil out when changing the oil and before removing the pan to change the filter. I have reused the spring clamp and now learned that the spring clamp should not be reused as it gets weaker when it is removed.
