Can't be normal: Transmission makes loud hard shifts

[Keith88]

My trans was replaced at 8k miles after it ate a gear. I have goosetuned withe TCM maping and it does the hard shift/drop coming to a stop at least once a week. Sucks.

It is normal if you make it normal

The transmission learns over time. If you have it in sport and drive it like a race car, it's going to do that. If you drive it like it's in normal while in sport mode, it is a much better, but aggressive still, style of drive.

It takes about 500 miles or so for it change around.

I don’t drive very aggressively at all. I drive it pretty Normal. It’s not as bad when in normal mode though. In Sport mode it’s done it a couple of times, but the one I mentioned was by far the worst.
