I'm fairly confident OTA updates are not available for engine and transmissions files. These have to be performed at the dealer.

Not true they can update the PCM OTA just ask those of us who had our aftermarket tune wiped out by this update.

The transmission does shift much smoother however I have noticed some surging in the 4th to 5th shift under moderate acceleration. I think its a lockup issue where it cant decide if its going to lockup the converter or not.

I had my TCM updated two weeks ago, while my pickup was in for the max tow axle/bolt replacement.

Haven't looked at my update code, but my pickup seems to be shifting better with no clunks on downshifts now.

Interesting, I know you can perform software updates to all modules. I did not know you can adjust the actual tune parameters such as fueling, timing, shift schedule, shift points etc...

Now that you mention it, I haven't noticed the clunky downshifts when slowing for a stop. Either I am so used to it, or it did go away. I will have to tune in a bit more and see whats what.

Having "tuned in" a bit better, I would say that the clunkiness is now less often, but still definitely there once in awhile. I think I have gotten used to it, so it's ignored a bit, and it happens a bit less often.
