In some vehicles, you may find aftermarket or factory transmission oil coolers. These can be built into or affixed to the very front of the radiator. The system is quite simple: the oil pump pumps the oil from the engine through a set of special lines over to the front of the automobile where it moves through a series of finned pipes. If a leak happens to occur in the cooler, the novice DIY mechanic should have no trouble removing, repairing and replacing an aftermarket cooler. In this article, we will walk you through the process of transmission repair cooling line diagnosis, removal, repair and replacement.

In order to gain an accurate read of the location, you'll need to wipe the oil away with a towel, making certain that the line is as try as possible.

Step 3 - If you find that the problem line is a steel one, the line nut should be turned counterclockwise to remove it. In some cases, you may even be able to remove the line with a light tug. If you require a steel line replacement, keep in mind that the line must be fitted to your vehicle. With a new gasket, affix the new line to the transmission by way of pressing it to the opening and screwing the nut in a clockwise fashion. Your other end will be affixed to the rubber line.

Step 4 - Start your vehicle and use your dipstick to make sure the correct amount of fluid is in place. If you require more, be sure to add the correct type of fluid to the proper level. In some cases, coolers will need an extra quart of fluid to account for the condenser and lines.
