My girlfriend has a 02' GXE w/ 50k miles. The shifter sticks in third gear and is tough to get out. At times I have to give a good pull to get it out of third. Nissan tells me the transmission fluid needs to be changed but they are not positive that will correct the problem, its also not covered under the warranty. I'm going to change the fluid this weekend but wanted to see if anyone has ever experienced this problem and knows what to do. Thanks.
