Hi Scotty!
I drive a 2010 Nissan Cube S with a 6MT. As of late I have issues trying to shift my car into 4th, 5th and 6th gear even when the engine is turned off. I took my car previously(3 months ago) to the dealer when I had the same issue except I couldnt shift into reverse they said there was nothing wrong with my car. efore I pay another $200 diagnosis do you think the issue is the clutch, trans or gear box? Or even worse should I look into selling this and buying a new car?
I appreciate your help and time. Thank you

Most likely an issue with the gearbox, more specifically the synchros. It's not the clutch because you can shift from 1st to 3rd you say. The clutch has nothing to do with whether you can physically shift through gears with the shifter; it just disconnects the engine's power from the transmission in order for you to properly shift gears without grinding them. If there is no warranty or if the dealership doesn't cover the cost to repair, then I would get rid of the car and look for a new one. Not worth repairing/replacing the transmission.
I agree with Razmig, it's probably the synchros. One thing you could check before going the rebuild route is to checkthe nylon shift bushing and guide at the base of the shift lever to see if it's worn out which might preclude your shifting into the higher gears. If that's the case, you have a relatively cheap fix. Good luck!
I read that the 6MT gear selector possibly has a cable linkage. A cable that is stretched or out-of-adjustment could conceivably lead to shifting problems, and might be an easy inexpensive fix.
You shouldn't let the dealer tell you there's nothing wrong when there obviously is. You've been driving without reverse for 3 months?
Find someone that sees your problem and let them fix it.
I appreciate your help guys. The dealer had the nerve to ask me if I even knew how to drive a manual transmission, same dealer I even bought the car from in 2010. But they said it was working fine and that I may not know how to drive it correctly and when I got in it drove fine. I smelled a burning smell as I drove it kinda home but it worked going into reverse (which it sill does currently). I just cant now go into 4th, 5th and 6th. Its almost like its blocked when moving the shifter.
you may want to try an independent shop, and have them test drive the vehicle and shift those gears.
Find someone that knows how to "float shift" the transmission. If it is the clutch cable you should be able to adjust RPM to get gears to move, without the clutch. If it is the transmission you cannot float shift gears.
If it is your clutch cable, get it fixed one time and sell it.
if gears 1,2,3 work but 4,5,6 don't, then it's unlikely to be the clutch cable, don't you think?
I had a Chevy Chevette that had a cable clutch. The cable stretched and stretched. Shifting changed with the length of the cable. Eventually I would put transmission in gears, with motor not running, and start car in gear. Then I could shift without clutch by matching RPMs for each gear. I got rid of that car after replacing the cable twice.
To know for sure the shifting could be checked by float shifting. That can tell more about what is good or bad about gears, and/or clutch. Just to say certain gears indicate problems may be true with normal linkage shifting trans. JMHO. This far from what is happening makes it all a guess. {black}:grinning:
