Komatsu D65 bulldozer is stuck in forward. Soon as u crank it up ur going forward. U can turn left and right but won't stop or go in reverse. Its no the ppc valve I have already taken it apart and inspected it all springs and valves are fine.

SOURCE: my car will not go in reverse but will go forward

typical FWD GM transmission issue, the transmisson will have to be rebuilt. You could try a fluid flush and filter change but there are only 2 discs pack for reverse. Which makes them fail very easily

SOURCE: No reverse movement after valve body was removed and cleaned

Stupid question here, but did you put the valve body in backwards or upside down? Ensure all the connectors, lines are good....outside of that how about the gear selector? I have done alot of tranny work myself, but some of these things are common mishaps that I have done myself. Good luck to you and let us know what you come up with. Thanks for using Fixya!

Sincerely,

SOURCE: Driver's seat unable to move forward or backward

There are plastic gears connecting the track to the seat assembly. Whne one of these strip the seat will only work or move to one side. Infiniti does not sell a simple fix. You are looking at buying an entire seat assembly complete with the module for all the electronics. It will be at a cost of around $950 - $1000. Once that is in, Infiniti must program the seat to the brain of the car, only then can you reset your memory settings.

Hi,
Yes, this is normal while in four wheel drive on pavement.
I will try and explain why.
In four wheel drive the front and rear drive axles are linked together by a chain in the transfer case and gears in both axles. This is a direct link with very little play between the front and rear axles.
When cornering a rear wheel will spin faster, or slower depending on the direction of the turn. this causes a binding in the drive line because the drive line wants all the wheels to turn at the same speed. So the wheel "skipping" going in reverse, is the drive lines way of compensating for the different speed of the wheels turning.
Never should a four wheel drive be used on dry pavement. I could cause a break in one of the drive line components. On a slippery surface , snow, mud, gravel, grass, There is enough slippage in the surface to aloow the driveline to compensate for the different speeds of tire rotation.
So do not try at highway speeds on dry pavement.
Your four wheel drive system is working just fine.
