How To Repair Transmission Fluid In Trans Cooler

Transmission and Transaxle Oestrus Temperature Failure Chart

Overheating is a Transmission Killer

According to The Automatic Transmission Rebuilders Clan (ATRA), an International trade association for the professional automatic transmission repair industry, approximately xc% of all automatic transmission failures are due to fluid (ATF) breakdown acquired by excessive estrus. As ATF heats up it becomes oxidized and loses its ability to lubricate and cool the manual. Poor lubrication causes friction, which produces more rut. This is why information technology is extremely important to routinely cheque both the ATF level and status in your vehicle.

Spending 5 to x minutes one time a calendar month checking your vehicle's manual fluid level and condition could save you lot thousands of dollars in repair bills.

The problem of transmission overheating tin be resolved past installing an auxiliary transmission oil cooler. As a DIY projection, yous'll pay between $30 and $threescore for the oil cooler and spend 1 one/2 to 2 hours on installation.

You lot can have a local manual shop install a transmission oil libation in your vehicle. Wait to pay betwixt $150 and $250 for the task. Either way, installing an auxiliary transmission oil libation is one of the all-time investments you tin brand in protecting your manual from overheating and certain failure.

Continue your transmission from overheating and yous eliminate the #1 cause of premature transmission failure.

As repeated throughout this Website, excessive heat is a transmission killer. Proceed 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 cooler. The cost is minimal and the installation is piece of cake. A person with minimal automotive skills can install a transmission oil libation in a couple of hours or less.

Notation: Installation instructions may be included in the transmission oil cooler kit y'all purchase. If so, follow those instructions first and employ this information only if needed.

TOOLS NEEDED

>Screwdriver for hose clamps
>Pliers
>Hand Drill and a selection of drill $.25
>Razor pocketknife to cut rubber libation hose
>Hacksaw or pocket-sized piping cutter to cutting cooler lines
>A drain pan or pocket-sized container to catch fluid

Before you lot begin:

i.Cut hoses and then they are a couple of inches longer than your rough measurements.

2.The cooler must mount no closer than ane/2" in front of the radiator or A/C condenser. The secondary transmission cooler must exist securely mounted then that information technology does not come in contact with any moving parts.

Mounting the Cooler

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

2.Discover the oil libation lines. These are metallic tubes that connect to the transmission on one end and the radiator at the other end.

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

four.With the mounting hardware provided with your oil cooler kit, mount the cooler one/2 to 1 inch in front of the radiator or A/C condenser.

Note:The cooler may be mounted in a unlike location, merely doing so may reduce the cooler'south effectiveness.

Connecting the Libation

1.Connect the cooler using the illustration below as a guide. On all automated transmissions, the manual oil flows from the manual through the original equipment libation, (which is located within the radiator), and so back to the transmission.

When a auxiliary transmission oil cooler is installed, the heated transmission oil flows from the transmission to the original equipment oil libation inside the radiator – then to the auxiliary oil cooler and and then dorsum to the transmission. See illustration beneath.

two.Place a grab pan under the radiator. Using an open up-finish wrench, disconnect one of the oil libation lines where it enters the radiator. At present, ensure that the vehicle cannot start during cranking. Have a helper crank the engine for but a few seconds. The transmission oil will menstruation 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 asunder cooler line, it ways the oil flows out of the radiator at the other cooler line, making it the outlet.

At present that you know which is the outlet, install the hose connector adapter that came with the auxiliary oil cooler kit to the outlet neck on the radiator.

iii.Attach the safety hose to either of the outlets on your new auxiliary cooler. Slip a hose clamp over the connection bespeak. Run the other end of the hose to the adapter y'all placed on the radiator in the previous step. Marking the needed hose length and cut hose accordingly. Slip the hose over the adapter plumbing equipment and secure with a hose clamp. Tighten hose clamps to 15 to 20-inch pounds of torque.

four.Echo these same hose plumbing equipment instructions for the 2d hose – existence certain to torque the clamps at 15 to 20-inch pounds.
