GM 4T40E, 4T45E Valve Body 1997-2001 – Updated, Tested, MADE IN USA
2nd(02-03) Design 4T40E Valve Body. First design valve body (97-01) has a hollow. Costs are just too high to make that realistic. Granted a used part may last you 100,000 miles depending on it’s previous use, or it may last you a month, you just don’t know.
