Hi all. I am new here. Bit of background. My 2nd 04 xterra and love them. The one I have now is a 04' V6 manual with 111,000 miles on her now. I have a huge issue I need help with. The trans is stuck in 3rd gear. I accelerated to to 3rd and tried to downshift and it just was stuck in 3rd nothing i could do. I pulled to saftey in a parkinglot. the cluth works, I can press the clutch and roll the truck. I can start it but cant get it out of 3rd. I replaced the clutch about 5000 miles ago, made sure the trans fluid was full and now this. I am at a loss. I'm not sure if it is a sycro, or if there is something else in there it could be. I am not afraid to do the work I just need my truck back on her feet. Any help would be awesome. Thanks
