I pulled my 2002 4L60E tranny servo out and took it to the chevy dealership where my bud works. We started looking up the part # for a 2002 and up vette servo and found that all the way up to 2006, cars and trucks with a 4L60E pretty much use the same part number. So if you're thinking of putting a vette servo in your truck and it's newer than 2002, you might already have that servo in your tranny. Thought you guys would be interested in this info. Feel free to comment if you found different. Like I said this is info only.
