How To Install Transmission Oil Cooler Lines

Transmission and Transaxle Heat Temperature Failure Chart

Overheating is a Transmission Killer

According to The Automatic Transmission Rebuilders Association (ATRA), an International trade association for the professional automated transmission repair industry, approximately 90% of all automated transmission failures are due to fluid (ATF) breakdown caused by excessive heat. Every bit ATF heats upward it becomes oxidized and loses its ability to lubricate and cool the manual. Poor lubrication causes friction, which produces more oestrus. This is why it is extremely important to routinely check both the ATF level and condition in your vehicle.

Spending five to 10 minutes one time a calendar month checking your vehicle's transmission fluid level and condition could save you thousands of dollars in repair bills.

The problem of transmission overheating tin can be resolved by installing an auxiliary transmission oil cooler. As a DIY project, y'all'll pay between $thirty and $60 for the oil cooler and spend ane 1/ii to 2 hours on installation.

You can accept a local transmission store install a manual oil libation in your vehicle. Expect to pay betwixt $150 and $250 for the job. Either way, installing an auxiliary transmission oil cooler is i of the best investments you can make in protecting your transmission from overheating and certain failure.

Keep your transmission from overheating and you eliminate the #1 cause of premature transmission failure.

As repeated throughout this Website, excessive heat is a transmission killer. Keep your manual from overheating and your chances for transmission failure are drastically reduced.

The all-time way to insure your manual does non overheat is to install an auxiliary (secondary) transmission oil libation. The cost is minimal and the installation is easy. A person with minimal automotive skills can install a transmission oil libation in a couple of hours or less.

Note: Installation instructions may exist included in the transmission oil cooler kit yous purchase. If so, follow those instructions kickoff and use this information only if needed.

TOOLS NEEDED

>Screwdriver for hose clamps
>Pliers
>Hand Drill and a option of drill bits
>Razor knife to cut rubber cooler hose
>Hacksaw or small pipe cutter to cut cooler lines
>A drain pan or small container to catch fluid

Before you begin:

1.Cut hoses so they are a couple of inches longer than your crude measurements.

2.The libation must mountain no closer than i/2" in front of the radiator or A/C condenser. The secondary transmission cooler must exist securely mounted and then that it does not come up in contact with any moving parts.

Mounting the Cooler

1.The transmission libation kit you lot purchased volition include the mountingtransmission oil cooler hardware needed to mount the cooler. The libation should be mounted ½ to 1 inch in front of the radiator or A/C condenser for vehicles with air conditioning.

two.Find the oil cooler lines. These are metal tubes that connect to the manual on 1 end and the radiator at the other end.

iii.Position the auxiliary transmission oil cooler and then its inlet and outlet tubes face up the existing manual oil cooler lines.

iv.With the mounting hardware provided with your oil cooler kit, mount the cooler i/ii to ane inch in front of the radiator or A/C condenser.

Annotation:The cooler may exist mounted in a different location, but doing so may reduce the cooler's effectiveness.

Connecting the Cooler

i.Connect the cooler using the illustration beneath as a guide. On all automatic transmissions, the transmission oil flows from the transmission through the original equipment cooler, (which is located inside the radiator), and so dorsum to the transmission.

When a auxiliary transmission oil cooler is installed, the heated transmission oil flows from the transmission to the original equipment oil cooler inside the radiator – then to the auxiliary oil cooler and and so back to the transmission. See analogy below.

2.Place a catch pan under the radiator. Using an open-end wrench, disconnect one of the oil libation lines where it enters the radiator. Now, ensure that the vehicle cannot showtime during cranking. Have a helper crank the engine for just a few seconds. The manual oil volition flow either from the radiator (where you removed the cooler line) or from the asunder cooler line. If the oil flows from the radiator, this is the outlet. If the oil flows from the disconnected cooler line, it means the oil flows out of the radiator at the other cooler line, making it the outlet.

Now that yous know which is the outlet, install the hose connector adapter that came with the auxiliary oil cooler kit to the outlet cervix on the radiator.

3.Attach the rubber hose to either of the outlets on your new auxiliary libation. Slip a hose clamp over the connexion point. Run the other end of the hose to the adapter you placed on the radiator in the previous step. Mark the needed hose length and cutting hose accordingly. Slip the hose over the adapter fitting and secure with a hose clamp. Tighten hose clamps to xv to xx-inch pounds of torque.

iv.Repeat these same hose fitting instructions for the second hose – being certain to torque the clamps at 15 to 20-inch pounds.
