No, but the current one needs to be serviced. The Pathfinder should have computer controlled shift solenoids, so have a dealership/transmission shop diagnose a possible electronic problem with your transmission. I would also a transmission flush followed by a filter change done because the problem could be debris is the line going to the LO-Reverse clutch. If that doesn't work, then the transmission needs to be rebuilt by a professional (if you have never been inside a transmission you cannot do the rebuild yourself). If you cannot afford to have the transmission rebuilt, then you might be able to get a replacement one out of junkyard. I caution you on a junkyard transmission, because they have been exposed to the elements, they have a tendency to fail.
could be either transmission shift linkage not engaging reverse ( stops at neutral ) worn joint connectors sometimes cause this. or reverse clutches or gears bad inside transmission.
Low Transmission fluid
it needs a new transmission
Transmission is going out. Reverse is always the 1st one to go.
Be sure that when you put the unit in reverse that the blades for the mower are not engaged. That will prevent the mower from operating
Put it into reverse when moving rapidly forward.
Transmission problems.
Put the van on the lift and drain the transmission fluid, next drop the transmission on a tranny jack and proceed to do a transmission overhaul. Reverse the proceedure to install.
The reverse is "shot" on your transmission. You'll need to either rebuild/replace the transmission or get another vehicle.
PULL WHOLE TRANSMISSION OUT AND PUT ONE IN . TAKE BOLTS FROM AROUND ENGINE THEN TRANSMISSION MOUNT A SLIDE BACK THERE GOES. TRHANKS!!
If you mean the transmission itself shifts forward, it is because the transmission is suspended, so when the transmission is put in reverse gear the momentum will push the transmission forward. Now, if the car pulls forward when put in reverse, this means there is a transmission problem. This may just indicate the shift linkages need adjustment, or that the transmission has a major problem and needs repairing. Take it to a shop and have it checked.
that happens to me also, but to avoid the noise before going into reverse put in in first then put it in reverse that'll work!
