^So do I.
I have about 25k miles on a 5.3/10speed. Trans is great, so far. Only complaint, if I had to find one, is either 9th or 10th seems pretty useless, as it only provides about a 150rpm split.
I think we’ve now hit about the practical limit for number of forward speeds. Honestly don’t notice much difference than the GM 8 speed or Dodge 8 speed, but all are a significant improvement over the 6 speeds that they replaced.
Wouldn’t hurt my feelers to have 3.73s behind my gasser though, if they offered it.
