What's the failure rate on the GXP transmission?

[Xanthous]

If I buy one, am I sure to replace the transmission or do some cars go their entire life with no problems?

All depends on driver but yea chances are you will end up replacing/rebuilding.

Dealer replaced the trans in my 06 monte carlo ss six months and 10k miles after i bought it brand new. Only LS4 i've owned, but it got replaced early on. I would guess the rate is probably over 50%.

The other half probably need to, but haven't.

Get the cooler get a tune get a shift kit. I'm at 105k stock trans. Nitrous e85 and a Good amount of mods

just under 100k and it got a shift kit at 85k . no slip. strong. stock

It's all about the driver, and not willfully ignoring maintenance.

Put a transmission in mine at 60k.

Torque Converter failed.

Had a shift kit and a huge trans cooler with a tune.

Figured it was doomed from the get go. One less thing I have to worry about.
