I HAVE A 08 GTS LANCER AND THE TRANSMISSION WHEN YOU PUT REVERSE THE CAR START LIKE JUMPING AND WHEN YOU GO FORWARD WITHOUT ACCELERATE IT DO SOME WEAR NOISE

check your idle sensor?

remember be carefull and never force anything take pictures as you progress to help remember how it goes back together

Something on the intake side of the motor may be loose sucking air casing the engine to compensate by adding more fuel

Remove drive belt. Remove bolt and belt tensioner assembly. Reverse procedure to install

shake the wheel as you turn the key.

I was a little leary myself when i bought the my 08 lancer gts cvt. I have only owned it for three months and has a little over 51000 km on but havent had any problems with it. You will be very impressed with the smooth operation of the cvt, the sprotronic and paddle shifters are amazing and work beautifully. I would recommend it over a regular five speed or a rough changing auto tranny. Besides the fact you should have proper warm up for it to work in colder temps(which is good for all trannys anyways) and the special transmission fluid needed. Fewer components and operates much like a snomobile belt drive system which i thought might affect gas mileage but i got a suprising 42mpg at 100km/hr. Towing anything might be an issue with this transmission since its a belt drive system(small camper or travel trailer) but im not to certain about that.So far so good......i would get another one!

is this car still under warranty? if so take it back to the dealer and don't accept it as repaired till you drive it. sounds like the logic that controls the transmission is flipping out, sometimes they will tell you that it needs a reflash. what this amounts to is that the manufacturer put some not so great programming in the logic when they built the car but now they have a patch or fix that makes it work better but you have to pay them for their time to install the fix. ask them what they will charge you for the privilege and decide if it's worth it to you. there is a recorded technical service bulletin about harsh shifts for your car. well, actually there are two, the latest one a revision of the first. i would try to make this their problem, it really is. hope this helps.

Sounds like a stripped reverse gear. And for the second gear probally need a new gear (1st 2nd) and the syncros with a new hub. If too much metal from the gears has already made it's way around in the bearings through the transmission oil you might be looking at a new transmission. The Golf 3 generation had many problems with reverse gears. Sorry to be the one to tell you.
