There was an issue with 8-speed transmission shutter which can be fixed by flush and replacement of transmission fluid. There was a service bulletin for that issue. Mine never had that problem.e-lockers are a factory option ?
I'll have to look cuz a 2 ddor is just the right size for me.
So I just went to Chev to check out the Colorado and trying decide on rear ratios I googled to see the 8speed ratios. WOW first thing up was "problems with the 8speed" I think I'll wait a few years and miss the experiment.
And YES - front and rear e-Locker standard in the ZR2!!
