profit organizations. MAP conducted pilot programs in twelve states
before announcing the program nationally in October, 1998. During the
pilots, participating repair shops demonstrated their adherence to the
Pledge and Standards and agreed to follow the UICS in communicating
the results of their inspection to their customers. To put some
"teeth" in the program, an accreditation requirement for shops was
initiated. The requirements are stringent, and a self-policing method
has been incorporated which includes the "mystery shopping" of
outlets.

MAP UNIFORM INSPECTION GENERAL GUIDELINES
OVERVIEW OF SERVICE REQUIREMENTS & SUGGESTIONS
It is MAP policy that all exhaust, brake, steering,
suspension, wheel alignment, drive-line, engine performance and
maintenance, and heating, ventilation and air conditioning, and
electrical services be offered and performed under the standards and
procedures specified in these sections.
Before any service is performed on a vehicle, an inspection
of the appropriate system must be performed. The results of this
inspection must be explained to the customer and documented on an
inspection form. The condition of the vehicle and its components will
indicate what services/part replacements may be "Required" or
"Suggested". In addition, suggestions may be made to satisfy the
requests expressed by the customer.
When a component is suggested or required to be repaired or
replaced, the decision to repair or replace must be made in the
customer's best interest, and at his or her choice given the options
available.
This section lists the various parts and conditions that
indicate a required or suggested service or part replacement.
Although this list is extensive, it is not fully inclusive. In
addition to this list, a technician may make a suggestion. However,
any suggestions must be based on substantial and informed experience,
or the vehicle manufacturer's recommended service interval and must be
documented.
Some conditions indicate that service or part replacement is
required because the part in question is no longer providing the
function for which it is intended, does not meet a vehicle
manufacturer's design specification or is missing.
Example:
An exhaust pipe has corroded severely and has a hole in it
through which exhaust gases are leaking. Replacement of the
exhaust pipe in this case is required due to functional
failure.
Example:
A brake rotor has been worn to the point where it measures
less than the vehicle manufacturer's discard specifications.
Replacement of the rotor is required because it does not meet
design specifications.

SERVICE INTERVALS
Transmission
Check fluid level and condition of fluid at each engine oil
change. Under normal, light duty operating conditions, change fluid,
replace filter and adjust bands every 2 yrs. or 25,000 miles. Under
heavy duty service, change fluid, replace filter and adjust bands
every 12 months or 12,500 miles.
Transfer Case
Check transfer case fluid every 12,000 miles and replace
fluid every 30,000 miles.
CHECKING FLUID LEVEL
Transmission
Park vehicle on a level surface and apply parking brake.
With engine idling at normal operating temperature, move transmission
selector lever through all gears, ending in "N" ("P" for AW-4
transmission). Check fluid level. Fluid level should be between
"FULL" and "ADD ONE PINT" mark on dipstick. Add fluid as needed. DO
NOT overfill.
Transfer Case
Remove fill plug. Check oil level. If level is not up to
fill plug opening, add lubricant until it is.
RECOMMENDED FLUID
Both transmissions and transfer cases use DEXRON-II ATF.
FLUID CAPACITY
NOTE: Transmission and converter capacities are approximate. Fluid
level should always be determined by reading on dipstick,
rather than amount of fluid added.
