Check the transmission fluid for level and condition topup or change then try driving forward or back if that sorts it

No reverse gear, please help - Nissan Forum

The Trans is on it's way out. Your best bet is to get a used one. Usually when they go out that is it they wont move at all.

is it with automatic gearbox?

Mke sure that the transmission is working. you can tell if the engine rpm changes when you put it gear (forward or reverse) if it does not then you need to check the level of the transmission fluid for an automatic or you may have clutch problems if it is a manual transmission. if you have more details on the transmission type (auto or manual) and if it is doing anything when you try to get it to move that would be helpful.

Sorry, no solution. I have the exact same problem and it started about the time you posted your problem. If anyone offers a suggestion, please let me know too. thx.

im pretty sure your transmission is going out on the car.you say it wont move in reverse and has hesitation going forward...id say start looking for another transmission or another car

check the transmission fluid level and condition

It sounds like you are starting to develop a serious issue with the inner workings of your transmission, possibly with the torque converter. I'm afraid the only solution to this issue is to have a mechanic look at it, as you might be forced to rebuilt the transmission, or get a used replacement. Unfortunetly they are almost impossible to service yourself, so I would search for someone who can give an assessment and quote for repair, preferably someone who specializes
