Default How many miles is too much for a new corvette servo?

Hello,

My 03 Silverado 4.8 with a 4l60e has 144,000 miles(only trans service while truck was in my possession since ownership at 94,000 was dropping the pan and replace the filter at 130ish and draining the fluid from the drain plug and refilling at about 140ish but the trans shifts really well no shift flare or anything so would putting a corvette servo in be a bad thing for a higher mileage trans or still a really good mod and on that note where is a good place for me to get one? Are there different corvette servos or all they all the same? Thanks in advance

I would not be concerned in the least.

Did mine at 145k miles. It's great. With tuning torque management even better!

Friend of mine put one in at 185,000 and never had an issue!! His truck has about 245-250,000 on it now.... Waiting for a phone call that he finally blew it up!!! Its still stock 60e in a 2000 tahoe....apparently his entire trans was built on a wednesday!!!

Did Mine at 159,000 and works fine. It certainly was worth the $15!
