I have a 1999 Chevy Express 2500 and a 2000 Chevy Express 3500 with 5.7 V8 and they both have a 4L80-E transmission in them. they are NOT cheap to rebuild. Over $2100 to rebuild one.
In front of the radiator.
those would be your transmission cooler lines.
Purchase an aftermarket cooler and follow the instructions included with the kit.
Yes.
It has no drain plug on the A/T.
Purchase the cooler of your choice. They come with complete instructions. Very easy job, and this would be a good time to change your transmission fluid.

The 1997 Chevrolet express 7.4 liter engine should never have transmission fluid point into it. The engine holds 6.4 quarts of motor oil. The transmission holds nine quarts of transmission fluid.
