8 speed transmission experience.

[Hillwood]

We all know that the 8 speed transmission is a problem child..  

Let's hear from those who have not yet had problems and how many miles on these..

Mine so far (knock on wood) has been good and smooth in every aspect..

3400 miles with fingers crossed!

I wish you well. I think both of mine started at about 15,000 miles. Fortunately the dealerships now know what to do to get you past the warranty period!

2015 Sierra 1500 Denali. 64K miles. Shifts nicely. Dealer did the 60K flush (or said they did) and have no issues.

2015 Silverado LTZ Z71, 123,249 miles. Shifts smooth, and things really pick up when you floor the loud pedal
