Hi all, I don't know if I'm the only one experiencing this issue but my transmission seems to shift sloppy after the Learn period. What confuses me is, I'm not a lead foot... I baby my vehicles... I've taken it to the dealership 3 times.. and they always tell me... it just needed to be Flashed and relearned... which basically starts all over... has anyone dealt with this issue?

My 2014 Jeep Compass Latitude 4x4 - 2.4l 6-speed automatic has 11,000 miles.


my thoughts are, the dealership is very much aware of the goofy issue and refuses to fix it ... OR there is no fix, this is just a poor Korean-made transmissions that they decided to use, and it is what it is...
So it seems the simple fix it to reset the transmission's learn mode free every time until the customer is out of warranty.

To follow up with this, I took it into the dealership and got it back eventually. They apparently had a Flash update for the TCM (Transmission control module)... Apparently this was new since the last time I took it in which was just this past summer. It helped the odd shifting and lack of power. Its funny how a simple Flash to the computer module solved the problem.

There were a load of flash updates for the CVT but I am almost certain you are better off with the 6 speed than a CVT.

All transmissions are electronically controlled unless you invoke Shift Tronic mode or whatever Jeep calls it. You can control the shift points up/down within reason.

Too many factors come into the shifting of a transmission these days. Sensors and tuning all worked out in advance. Apparently they require post service follow up. The dealer typically checks for outstanding updates when you have it in for something else and apply the various flashes released.

The CVT offered no millage gain as I am typically 10MPG under advertised rating. LOL most others are as well. At least in Canada, the US rating was much more government controlled but the Canadian MPG rating was at the whim of the manufacturer and they could put any number they wanted without real world testing to see if it was achievable. I got changed this year as I recall so its closer to reality.

I think anyone buying a new vehicle needs to rent one for a weekend of driving and go on a long trip to get the feel and see for themselves what the MPG actually is. I find that short trips are shadowed by inattentive senses and belief of the dealer and sales info as fact. Not true in most cases unless verified carefully.
