I'm draining the trans pan on my Silverado. I noticed how close the exhaust pipe is to the pan. Ive seen trans temp as hi as 280 on a warm day towing a fully loaded toy hauler. That temp is/was only for short periods like going up a hill. I was told not to worry about it if it's for short periods and if it stays under 300. And change the fluid regularly. Which I do. It's 35k miles since I last changed the fluid and filter. So, in regards to the ex. pipe I wonder if I put a heat sheild of some sort between the pan and pipe if it would help at all.
