you should first check gear box oil ,level and clean filter.lee

Check Linkage for the 4WD transfer case, between the shifter and the case. if it is a direct case mounted shifter, you may need to remove it and check for obstruction.

Have you tried to shift it to 4H while at a slow roll in N? Sometimes that used to work for me in my older floor mount 4WD truck. Give it try!

I have the same problem. on the passenger side under the fender you will have access to the transmission. Remove the cap on the end. You will need to drain the transmission fluid and replace all the gears in the end cap if damaged hopefully they are not and you can just tighten up the nut. What happens is a nut comes loose and backs off the pressure on the bearings and you loose 5th. I removed the entire transmission and opened it up. There is nothing wrong with the other gears, because your problem is with the 5th gear synchronizer assembly. I let mine go too long and I'm having to replace everything. Make sure you put the appropriate torque on the nut and hit it with a hammer to lock it down. This should really be designed with a different method of keeping that nut in place. It's costing me lots of time and now money at the stealership. Good LUCK.

I also have a 2009 Outlander Sportronic transmission with a V6 engine.
Bought it this summer ... transmission appeared fine but seemed to automatically slow down the vehicle using the engines compression whenever I let go of the gas pedal.
Now that the cold weather is upon us here in Canada, whenever I accelarate normally (not like a teenager) the transmission takes quite a bit of time to shift into second... If I rev up the engine (quick take off) it seems to help but the shifting of gears is not as smooth as I would expect it (mildly slips and kicks into second)...

The worst is when come to a complete stop ... then the transmission kicks coming down from the higher gears???

I read somewhere that this is because this transmission is a CVT type and is learning my driving habits in order to adjust itself so the vehicle becomes more fuel efficient... Not sure but if the trany is computer controlled then it must be poorly writen program...
I'm taking the car in to the dealer and will write back on the diagnostic they give me ...
