Core Charge and Freight Extra
DHD does require cores on all Transmissions and Converters. To receive full credit your core must be in rebuildable condition, no case damage, catastrophic failures or hard part failures. The core you return must match the model and type you received. Cores do not need to function electronically and can smell burnt.
To avoid paying the core charge up front, you can select the "Return Core First" option in the menu above. Right above the add to cart button. When this option is utilized we will hold your order until the core is received.
Please see the attachment under the Documents tab, and the disclosure under the Warranty tab.
NOTE:Ability to hold horsepower is directly effected on driving habits and engine/transmission setup. Transmissions that are abused from excessive temperature and/or careless driving may not be able to withstand for extended periods (burnouts, donuts, exc). Proper engine /transmission tuning and common sense are essential to transmission life.
WHAT IS A WARRANTY?
In today’s world of lengthy auto warranties, both manufacturer and aftermarket “purchased”
warranties, misunderstanding can occur. Our customers, and their customers (the end user) encounter
problems at some point after their car has been repaired. We would like to set the record straight on
just what a “warranty” is, and how the warranty process works.
Many people today equate a warranty with automatic and total replacement of any part that goes bad
for any reason. While that may be true of an item for which an additional extended unconditional
warranty was purchased, the vast majority of parts, be they auto parts or any other commodity, usually
have a time limit or usage limited guarantee. This guarantee is very specific in nature to replacement of
any part found to be defective in its fit or function for the time limit specified. Manufacturers do an
extremely good job of making a product suitable for use in variety of situations, and durable enough to
hold up to the uses for which it was intended, however, after it has left their hands and has been sold
into the world at large, it’s impossible to foresee all the circumstances that may be encountered that
would cause failure. Many parts that are perfectly suitable for normal use are subjected to extreme
stresses and situations that test the limits of its function. Many, if not all, of these stresses come from
some form of excessive driver input.
It is impossible to control how a part is installed and used after its manufacture, warranties are put in
place to assure customers that they are buying a part off the shelf that meets all the specifications for
which it is intended. However, since there is no control of its usage, these warranties are SPECIFICALLY
LIMITED to defects in materials used and workmanship used to assemble the part in the factory. This
does NOT mean an automatic replacement of any part that has failed. Anyone considering asking for a
warranty on a part should first ask the question, “Why did the part fail?” Some reasons are pretty
obvious. Others are not. Since most factories put their products through several quality control checks
before being put up for sale, the first things one should consider are: How was the item used? What kind
of environment was it subjected to? If it worked when it was installed, why did it quit after “X” amount
Most new items that are installed and work right from the beginning will continue to work properly for
many weeks or years if installed correctly. Typically, a 90 day warranty is sufficient to address
manufacturing quality concerns. If a part holds up for that long, it is likely to continue to do so.
Whatever the time limit, it’s considered to be long enough to address quality and manufacturing
concerns. Other reasons for failure may not be so obvious. In those cases, the seller of the merchandise,
because of his or her experience in dealing with different types of failures of various items can make an
educated speculation about whether a failure classifies as a defect. However, in ANY and ALL cases, the
final determination of whether an item is actually a defect in manufacturing or materials or simply
subject to driver abuse, environmental stress, or other causes, rests solely with the manufacturer. All
parts sold by All Season Service/Dirty Hooker Diesel carry a 90 day warranty against DEFECTS IN
MATERIAL AND WORKMANSHIP. The exceptions being electrical merchandise and any item for which
the manufacturer has specified a longer time or mileage. Proof of material defects will be determined
first by All Season Service/Dirty Hooker Diesel, and in specific cases by sending the item to the
manufacturer for further examination.
WARRANTY DOES NOT MEAN UNCONDITIONAL REPLACEMENT
