Transmission
The transmission dipstick has a HOT and COLD range check. There’s a good rea-
son for that.
When removing the dipstick, make sure the gasket in the dipstick cap stays in
place. It has a tendency to come loose and stay on top of the transfer case. The gas-
ket is easily knocked off and lost in the vehicle’s hull.
Without the gasket, the dipstick doesn’t seal properly and dirt and other contam-
inants get inside the transfer case. Replace a missing gasket with NSN 5330-12-
124-0982.
Wheel Hubs
Oil levels in the wheel hubs should be
checked after operation—but not imme-
diately after. You need to allow about an
hour for the oil to run back from the plan-
etary gears into the hub to get an accurate
reading.
The correct oil level should be between
3/4 and 7/8 full in the sight glass.

Do a COLD range check a couple of minutes after startup to make sure there’s
enough oil in the transmission for operation. After the engine has reached operating
temperatures, do another check using the HOT range on the dipstick.
In both cases, the level should be between their respective ADD and FULL
marks.
Check the dipstick tube for cracks or leaks, too. An overfill, discolored fluid or a
leaking dipstick tube makes your Stryker NMC.
Transfer Case
Check the transfer case gear oil after operation. The oil level should be between
the two holes at the end of the dipstick.

T
he transfer on your Stryker takes some getting used to, drivers. If you don’t get
used to it fast, though, you
will
be quickly buying a new one.
The transfer has three settings: 4-wheel drive, 8-wheel drive high, and 8-wheel
drive low. If your Stryker is moving slow, you can shift from 4-wheel drive to
8-wheel drive high (and back again) while on the fly.
However, you should
never
shift from either 4-wheel drive or 8-wheel drive high
to 8-wheel drive low while the vehicle is moving. That rips up the transfer case.
When shifting into 8-wheel drive low, stop the vehicle, put it in neutral and then
flip the transfer case speed switch to take it to 8-wheel drive low.

I’ll be
