Re: After Tranny Flash 21-018-14

I hear it takes about 6k miles for these transmissions to complete the adaptive learn process. The flash helped mine greatly though with the rough shifts being gone.

Can't say how long on average it takes. I suppose it'll vary by person. For me it was around 300-350 miles.

Maybe macfan did get lucky. Maybe I got lucky with my 12/11 build.
I have not had any updates and the dealer did not want to do any either.
The eary builds had lots of adjustment issues with the AL process nessitating a whole string of TSB's.
* I am also old school on break in. I always stretch it out a bit longer and I do realize new parts like gears etc. will generate more heat. Heat can and will damage components (transmission) including fluids. Thus the speed/rpm restrictions. With a sealed transmission its a bit of a issue to check the fluid. In fact I went 1,000 miles w/o pushing it too hard.
* The shifting etc is AL (adaptive learn) related. Mine was rough but it cleared up and I did finish AL w/o transmission problems.
AL will adapt to an individual's driving as long as the driving falls with in the logarithms of the program. Thus the need for all those TSBs.
The TSBs merely helps the 9-speed finish the AL process. If one is done that is not needed you run the risk of screwing up the process.
I am a consistent diver, but not a Sunday driver. I did not hot rod it during the AL period. The TCM needed to learn. As my dealer told me in our TSB discussion he has one customer that will probably need 10,000 miles to complete.
Yes there will be transmission failures, which will happen on all brands.

But I think you need to break out actual failures from all the other issues like AL. Forums tend to exaggerate the problem also.
There are lots of Cherokees out there without a transmission failures.
Yes, I do believe that improper break in can/does contribute to some of these issues. All it takes is one screw up and the damage is done.
Its interesting to note that trailer break in has even more severe restrictions for initial towing. The reason is heat generated.
If I do not follow those restrictions I will then be rolling the dice for sure and needing to buy that lotto ticket to pay for that new transmission.
Oh that's correct, Chrysler is paying for it.
No luck here just old school common sense in break in procedures.

Re: After Tranny Flash 21-018-14

I'm 750 miles into my Trailhawk. During the first 300 there were some odd shifting moments, but now that I'm well past the initial 300-500 the car shifts so smoothly it's like a dream.

That's about how long it took for me.
It does vary by individual driving habits.
Short low mileage trips are the worst for AL. It does not allow the system to learn and retain the data. This type of driving might take 10,000 miles for AL to finish.
I also think AL continues in the background, continually adjusting.
I know I did not start using 8 gear on the highway till I had between 2-3,000 miles. I am sure that was a function of AL.
I just think that Chrysler could have done a better job explaining the AL process.
