How to Change the Transmission Fluid for a Grand Cherokee?
2 Answers
The methods for changing the transmission fluid of a Grand Cherokee are: 1. Gravity Drain Method: Loosen the oil pan bolt and allow the transmission fluid to drain out by gravity; 2. Machine Flush Method: Store new transmission fluid inside a flushing machine, connect the transmission to the machine via hoses, and use the machine to push out the old fluid with the new fluid. The Grand Cherokee is a mid-to-large-sized SUV under the Jeep brand, with body dimensions of 4828mm in length, 1943mm in width, 1792mm in height, a wheelbase of 2915mm, and a fuel tank capacity of 93.5 liters. The Grand Cherokee is equipped with a 3.0L naturally aspirated engine, paired with an 8-speed automatic transmission.
Changing the transmission fluid for the Grand Cherokee, I've done it myself several times. First, safely lift the car with a jack, ensuring the chassis is stable—this is crucial. Locate the drain plug at the bottom of the transmission oil pan, and slowly loosen it with a wrench, allowing the old fluid to flow into the drain pan. During this process, some residual fluid will remain inside the transmission, so it's best to let it drip for a few minutes. Next, remove the oil pan and replace the filter if there is one—the Grand Cherokee's filter tends to clog easily, so remember to clean the sealing gasket and apply new sealant. After reinstalling, use a funnel to add new transmission fluid, preferably ATF+4 type, filling to the amount recommended in the manual. Finally, start the engine, shift between P and N a few times, and check the dipstick to ensure the level is within the normal range. The whole process requires patience and having all the tools ready—don’t cut corners. Changing it every 30,000 miles can extend its lifespan, otherwise, increased wear can lead to costly repairs.
