1) Low-reverse band is rear band on transmission. Oil pan
must be removed from transmission to adjust low-reverse band. Raise
and support vehicle. Loosen oil pan bolts. Allow fluid to drain from
oil pan. Remove oil pan bolts, oil pan and gasket.
2) Loosen low-reverse band adjusting screw lock nut while
preventing low-reverse band adjusting screw from rotating. Low-reverse
band adjusting screw lock nut and low-reverse band adjusting screw are
located inside transmission, near low-reverse band. See Fig. 5.
3) Back off low-reverse band adjusting screw lock nut 5
turns. Ensure low-reverse band adjusting screw rotates freely in
transmission case.
4) Tighten low-reverse band adjusting screw to 72 INCH lbs.
(8.1 N.m). Back off low-reverse band adjusting screw specified amount
of turns. See LOW-REVERSE BAND ADJUSTMENT table. Hold low-reverse band
adjusting screw and tighten low-reverse band adjusting screw lock nut
to specification. See TORQUE SPECIFICATIONS.

5) Clean oil pan, magnet and all sealing surfaces. Using NEW
gasket, install oil pan. Install and tighten oil pan bolts to
specification. See TORQUE SPECIFICATIONS.
6) Add Mopar ATF Plus Type 7176 fluid until fluid level is at
MIN arrow mark on dipstick. Start engine and allow engine to idle.
With brakes applied, shift transmission through all gears and back to
Neutral.
7) Add additional fluid to bring fluid level to MIN mark on
dipstick. Recheck fluid level with transmission at normal operating
temperature. Adjust fluid level to MAX arrow mark on dipstick. DO NOT
overfill transmission.

Transmission (Dakota)
Check transmission fluid level when performing other
underhood services. Under normal service conditions, change
transmission fluid at 30 months or 37,500 miles. Under severe service
conditions, change transmission fluid at 18,000 miles. Severe service
are conditions such as long periods of engine idling, trailer towing,
off-highway operation, snow removal, or operating in dusty or
excessively hot conditions.
Transmission (Ram Pickup)
Check transmission fluid level when performing other
underhood services. Fluid change service interval information is not
available from manufacturer.
Transfer Case
Check transfer case fluid level when performing other
underhood services. On Dakota and Light-Duty Pickup, change transfer
case fluid at 37,500 miles or 30 months. On Medium-Duty and Heavy-Duty
Pickup, change transfer case fluid at 36,000 miles or 36 months.
CHECKING FLUID LEVEL
Transmission (Dakota)
1) Park vehicle on level surface. Remove transmission fill
plug from side of transmission. On AX-15 transmission, transmission
fill plug is located on driver's side of transmission. On NV3500
transmission, transmission fill plug is located near front of
transmission on passenger's side of transmission.
2) On all transmissions, fluid level should even with bottom
of fill plug hole on side of transmission. Add appropriate type of
transmission fluid if necessary. See RECOMMENDED FLUID. Install and
tighten transaxle fill plug to specification. See TORQUE
SPECIFICATIONS.
Transmission (Ram Pickup)
1) Park vehicle on level surface. Remove transmission fill
plug from side of transmission. On NV3500 transmissions, transmission
fill plug is located near front of transmission on passenger's side of
transmission. On NV4500 transmissions, transmission fill plug is
located near rear of transmission on passenger's side of transmission.
2) On all transmissions, fluid level should even with bottom
of fill plug hole on side of transmission. Add appropriate type of
transmission fluid if necessary. See RECOMMENDED FLUID. Install and
tighten transaxle fill plug to specification. See TORQUE

Transfer Case
Park vehicle on level surface. Remove transfer case fill plug
from rear of transfer case. Fluid level should even with bottom of
transfer case fill plug hole on rear of transfer case. Add appropriate
type of transfer case fluid if necessary. See RECOMMENDED FLUID.
Install and tighten transfer case fill plug to specification. See
TORQUE SPECIFICATIONS.
RECOMMENDED FLUID
Transmission (Dakota)
On AX-15 transmissions, use API 75W-90 GL-3 gear oil. On
NV1500 and NV3500 transmissions, use ONLY Mopar M/T Lube Part No.

the types of injector circuits that your noid lights are designed for.
There are three. They are:
* Systems with a voltage controlled injector driver. Another
way to say it: The noid light is designed for a circuit with
a "high" resistance injector (generally 12 ohms or above).
* Systems with a current controlled injector driver. Another
way to say it: The noid light is designed for a circuit with
a low resistance injector (generally less than 12 ohms)
without an external injector resistor.
* Systems with a voltage controlled injector driver and an
external injector resistor. Another way of saying it: The
noid light is designed for a circuit with a low resistance
injector (generally less than 12 ohms) and an external
injector resistor.
NOTE: Some noid lights can meet both the second and third
categories simultaneously.
If you are not sure which type of circuit your noid light is
designed for, plug it into a known good car and check out the results.
If it flashes normally during cranking, determine the circuit type by
finding out injector resistance and if an external injector resistor
is used. You now know enough to identify the type of injector circuit.
Label the noid light appropriately.
Next time you need to use a noid light for diagnosis,
determine what type of injector circuit you are dealing with and
select the appropriate noid light.
Of course, if you suspect a no-pulse condition you could plug
in any one whose connector fit without fear of misdiagnosis. This is
because it is unimportant if the flashing light is dim or bright. It
is only important that it flashes.
In any cases of doubt regarding the use of a noid light, a
lab scope will overcome all inherent weaknesses.
OVERVIEW OF DVOM
A DVOM is typically used to check injector resistance and
available voltage at the injector. Some techs also use it check
injector on-time either with a built-in feature or by using the
dwell/duty function.
There are situations where the DVOM performs these checks
dependably, and other situations where it can deceive you. It is
important to be aware of these strengths and weaknesses. We will cover
the topics above in the following text.
Checking Injector Resistance
If a short in an injector coil winding is constant, an
ohmmeter will accurately identify the lower resistance. The same is
true with an open winding. Unfortunately, an intermittent short is an
exception. A faulty injector with an intermittent short will show
"good" if the ohmmeter cannot force the short to occur during testing.
Alcohol in fuel typically causes an intermittent short,
happening only when the injector coil is hot and loaded by a current
high enough to jump the air gap between two bare windings or to break
down any oxides that may have formed between them.
When you measure resistance with an ohmmeter, you are only
applying a small current of a few milliamps. This is nowhere near
enough to load the coil sufficiently to detect most problems. As a
result, most resistance checks identify intermittently shorted
injectors as being normal.
There are two methods to get around this limitation. The
first is to purchase an tool that checks injector coil windings under
