Not normally, but yes they do. Brakes are designed to be replacable, servicable wear itmes, but not transmissions.
I wore out the tranny on my 1969 Saab 96. Now that I think about it, was it because as the second owner acquired at around 80k miles I subjected it to engine braking?
Do you suppose some trannys are better suited to abosorbing decelerating forces than others? It's the opposite side of the teeth and the bearings as acceleration.
I would imagine that the load could be the same as acceleration as with deceleration you can chirp the tires on a downshift too. And isn't the limit of the drivetrain forces determined by the weight of the vehicle and the traction availible, not the power going in?
So while I can, in a practical sense, appreciate the wisdom of wearing brakes and not trannys, I use engine braking frequently in my own personal cars because I feel the tranny wear should be negligible, but maybe that's not true as may have been the case in my own Saab 96.
