I was just wondering if anyone else has had this issue with having to replace the transmission cooler seal. I had my car up on the hoist and was told it was a seal for the transmission cooler. I have only about 47K miles on my engine, and all the sudden the seal is leaking. I know I need to have this fixed before I get a power flush with Amsoil done at 52K miles. Has anyone done this, and approximately how long did it take to do? I also need to replace the bypass hose as well for the anti freeze line which I would imagine does not take that long.
