With the truck safely positioned on a level surface, I remove the skid plate to access the transfer case, loosen the fill plug first, remove the drain plug, and allow the old fluid to drain. After reinstalling the drain plug, I use a fluid transfer pump to add fresh transfer case fluid through the fill opening. The complete process is shown step by step in the video. WHY SHOULD YOU REMOVE THE FILL PLUG FIRST? Before draining the transfer case, make sure you can loosen the fill plug. You don't want to drain the old fluid and then discover that you can't remove the fill plug to refill the transfer case. It's a simple step, but it's one of the most important things to check before starting a transfer case fluid change. HOW DO YOU KNOW WHEN THE TRANSFER CASE IS FULL? For the transfer case shown in this video, I fill it with the truck on a level surface until the new fluid reaches the fill opening. Always verify the proper fill procedure and fluid capacity for your specific transfer case before servicing it. WHAT TRANSFER CASE FLUID DOES A RAM 2500 USE? For my 2021 Ram 2500 6.4L HEMI, I used the transfer case lubricant shown in the video and linked above. Transfer case specifications can vary depending on model year and transfer case.
