I am going to change the transmission fluid soon so was wondering, is a deep transmission pan available for our trucks?

 

There are several manufacturers that make deep pans on these trucks. I put a B&M on mine which has a 4R75W but it also covers earlier models which have different bolt patterns. This causes a very slight seepage at the hole that is plugged. Mag Hytec has the best product for our trucks but they are more expensive. I think you would get what you paid for though. They come with the correct filter if you order it from them too.
