Toyota Repair: 05 Sienna, transmission leaks, fluid leak

Question
I just started a transmission fluid leak under my Sienna.  I have had no other mechanical problems with this van.  Are there any commonly occuring problems of this nature with 05 Siennas having 125,000 miles?  Thank You for your time.

Answer
There are two common areas that can cause transmission leaks, the oil pan or one of the drive axle seals on the side of the transmission. If the oil pan is leaking it has to be removed and the gasket replaced, in case the leak is on the side of the transmission where the axles go in then the axle has to be removed and the seal replaced.
