I was defending my 10 speed transmission for the past few months, but since I hit about 10,000 mi, it started acting like the ones everyone is complaining about.
Clunks, slips, and other assorted mishaps. The reprogram won't help because mine was built after the specified date. Don't know why this just started when it was fine for the first 10K.
Not very happy.

 

Have you tried simply disconnecting the battery for a while, and completely going thru the re-learn process.

If done properly, it made a world of difference on my truck.

You have to follow every step precisely and for the time mentioned.

I posted it back a while ago.

Couldn't hurt, just takes a little time.

 

There's a faster way. Do a can bus reset. Takes 10 minutes.
It seems like this started after I started running in sport mode a lot more often.

 

So how is that accomplished? thanks

 

Disconnect both battery terminals. Touch the negative cable to the positive cable for 5-10 seconds. Let truck sit for 10 min then reconnect to terminals. Done.

 

So basically short the system to drain it.
