  Q: How Often Should You Change Your Automatic Transmission Filter and Fluid on Dodge Ram 3500?

  A:

  For regular service, the fluid topping up after filter replacement is about 3.8 liters (4.0 quarts). First, lift the vehicle and support it on safety stands and afterwards put a large, shallow drain pan directly under the transmission pan. After removing the bolts that link the front and sides of the pan to the transmission, loosen those at the rear and carefully separate the front of the pan and reusable gasket from the transmission so the fluid can drain inside. Hold the pan upwards and remove the bolt from it. When done, place the pan back down and gasket with any remaining fluid drained into the pan. Remove the filter screws, remove the filter, dump any fluid in it into the drain pan and throw out the used transmission fluid and filter. Place the new transmission oil filter on the valve body and attach the screws, each to a snugness of 4 Nm or 35 inch lbs. After ensuring the ribs on the sealing gasket are intact, remove any debris from its place in both the transmission housing rail and Oil Pan and put it back if you see it's undamaged. Apply the gasket to the oil pan and put the oil pan and gasket onto the transmission, fasten several bolts first, then finish the rest and tighten them all to 13.6 Nm (125 inch lbs.). Lower the car as you add the proper amount of transmission fluid.

  Q: How to Service and Repair an Automatic Transmission Filter for the 45RFE/545RFE Transmission on Dodge Ram 3500?

  A:

  Raise the vehicle on supports safety and position a large shallow drain pan beneath the transmission, then service or replace the fluid filter for the 45rfe 4 Speed/545rfe 5 Speed transmission. Remove the front and side bolts from the transmission, loosen those at the back and gently remove the front of the pan so juice can flow into the pan. When the pan is resting evenly, take out the final bolts and pull the pan from the transmission, draining what's left of the fluid into the drain pan. After, remove the main Oil Filter screw (1) from the valve body, take out the filter and pour the remaining fluid from it into the drain pan. Review the oil filter seal at the oil pump; if you find it isn't complete or damaged, throw it away, but if it's fine, you might be able to reuse it. When changing the part 2, take out the cooler return filter using Oil Filter Wrench 8321 and properly throw away the old transmission fluid and used oil filters. Look at the bottom and magnetic part of the pan for a thick layer of metal; a small amount of clutch dust is normal unless it causes the car to slip or not shift smoothly. Rinse the pan and the magnet using a suitable solvent and remove the original seal from both the transmission case and pan with a gasket scraper. When fitting, place the primary seal of the oil filter so that it is flush against the oil pump so that it doesn't go on the neck of the filter. Should the seal wear out, install a new primary seal in the oil pump bore using the right equipment. Put the replacement filter into place on the valve body and into the oil pump and install the screw to hold down the primary oil filter (1), setting the torque to 4.5 Nm (40 inch lbs.). Should you need to, swap the cooler return filter and then adjust the screws to 9.5 Nm (7 ft. lbs.). Put some Mopar Rtv sealant on the transmission case, place the pan back on the transmission, tighten the bolts to 12 Nm (105 inch lbs.), lower the vehicle and pour Mopar Atf +4 into the transmission.
