Understanding Your 2014 Jeep Grand Cherokee Transmission Fluid Type
The 2014 Grand Cherokee model year introduced a significant change in transmission technology. Many models, especially those with the 3.6L Pentastar V6 or 5.7L HEMI V8, came equipped with the sophisticated 8-speed ZF 8HP automatic transmission. This is a crucial detail when selecting your transmission fluid.
This advanced transmission requires a very specific fluid to function correctly. Using the wrong fluid can quickly lead to expensive damage. It’s not just about lubrication; the fluid also acts as a hydraulic medium and a coolant.
The Specific Fluid: Mopar ZF 8-Speed ATF
For the ZF 8HP transmission found in most 2014 Grand Cherokees, the required fluid is
Mopar ZF 8 & 9 Speed ATF
. This fluid is specifically engineered to meet the demanding specifications of these modern transmissions. You might see it referred to as Mopar part number 68157995AB (or later revisions).
Do not substitute this fluid with generic multi-vehicle ATFs. The ZF 8HP transmission has tight tolerances and complex valve bodies that depend on the exact viscosity and additive package of the specified Mopar fluid.
Why Fluid Type Matters for Your WK2
The transmission fluid in your Grand Cherokee does more than just lubricate gears. It transfers power, cools the transmission components, and cleans internal parts. It also acts as a hydraulic fluid, enabling your transmission to shift gears smoothly and precisely.
Using an incorrect fluid can lead to a host of problems. These include harsh shifting, slipping gears, overheating, and accelerated wear on clutches and seals. For off-roaders, these issues can be magnified under extreme conditions, potentially leaving you stranded.
Identifying Your Grand Cherokee’s Transmission
Before you even think about buying fluid, confirm which transmission your 2014 Grand Cherokee has. While the 8-speed ZF 8HP is common, some earlier production models or specific configurations might have different units.
The most reliable way to confirm is to check your owner’s manual. It will explicitly state the transmission type and the recommended fluid. You can also look for a sticker on the transmission itself, though this can be difficult to access.
Common Transmissions in 2014 Models
*
ZF 8HP70 (8-speed automatic):
Most common, especially with V6 and V8 engines. This is the one that needs the Mopar ZF 8 & 9 Speed ATF. *
Older 5-speed or 6-speed automatics:
Less common for the 2014 model year, but always worth double-checking. These would require different Mopar fluids, such as ATF+4.
When purchasing fluid, always double-check the part number against your vehicle’s specifications. A few minutes of research can save you hundreds, if not thousands, of dollars in potential transmission repairs.
Checking Your Transmission Fluid Level: A DIY Guide
Unlike older vehicles, many modern transmissions, including the ZF 8HP in your 2014 Grand Cherokee, do not have a traditional dipstick for easy fluid checks. This doesn’t mean you can ignore it; it just means the procedure is a bit more involved.
This sealed-for-life design often leads owners to believe the fluid never needs checking or changing. This is a myth, especially if you drive hard, tow, or go off-road. Regular checks are still important.
Tools You’ll Need for the Fluid Check
* Jack and jack stands (or a lift) * Safety glasses and gloves * Torx bit set (specifically T40 for the fill plug) * Fluid pump with a long hose (optional, but helpful for adding fluid) * Clean drain pan * Scan tool capable of reading transmission fluid temperature (
essential
)
Step-by-Step Fluid Level Check
1.
Warm Up the Transmission:
Drive your Jeep for at least 15-20 minutes until the transmission fluid reaches its operating temperature (typically between 86°F and 122°F or 30°C and 50°C). This is crucial. A cold fluid check will give an inaccurate low reading. 2.
Park on a Level Surface:
This is non-negotiable for an accurate reading. Engage the parking brake. 3.
Shift Through Gears:
With the engine running, shift the transmission through all gears (P, R, N, D, 1, 2, etc.), pausing briefly in each. Then return to Park. 4.
Lift and Secure Vehicle:
Safely lift your Grand Cherokee using a jack and secure it with jack stands. Ensure it is level. 5.
Locate the Fill/Level Plug:
On the ZF 8HP transmission, the fill/level plug is typically on the passenger side of the transmission case, usually a T40 Torx plug. It’s often located above the main drain plug. 6.
Remove the Fill Plug (Engine Running):
With the engine still running, carefully remove the fill/level plug. 7.
Observe Fluid Flow:
* If a steady stream of fluid drips out, the level is correct. * If no fluid drips out, the fluid level is low. * If fluid gushes out, it’s overfilled (less common but possible). 8.
Add Fluid if Necessary:
If low, use your fluid pump to slowly add the correct
2014 Jeep Grand Cherokee transmission fluid type
(Mopar ZF 8 & 9 Speed ATF) through the fill hole until a steady stream begins to drip out. 9.
Reinstall Plug:
Once the fluid starts to drip, quickly reinstall the fill plug and tighten it to the manufacturer’s specified torque (consult your service manual). 10.
Lower Vehicle and Clean Up:
Safely lower your Jeep and clean any spilled fluid.
Safety First:
The engine will be running while you are under the vehicle. Always ensure your jack stands are stable and never rely solely on a jack. Wear appropriate personal protective equipment.
When to Change Your Transmission Fluid
Jeep and ZF often state “lifetime fluid” for these transmissions. However, “lifetime” often refers to the expected life of the warranty, not the life of the vehicle. For a vehicle you want to keep for years, especially one that sees heavy use or off-road action, fluid changes are essential.
Recommended Change Intervals
*
Normal Driving:
Every 60,000 to 80,000 miles (100,000 to 130,000 km) is a good general guideline. *
Heavy Duty / Off-Road / Towing:
Consider changing it every 30,000 to 40,000 miles (50,000 to 65,000 km). Heat is the enemy of transmission fluid, and these conditions generate a lot of heat.
If you’re unsure, a visual inspection of the fluid can also give clues. Dark, burnt-smelling fluid is a strong indicator that it’s time for a change, regardless of mileage.
Step-by-Step: Changing Your Grand Cherokee’s Transmission Fluid
Changing the transmission fluid on a ZF 8HP is more complex than a simple drain and fill on older vehicles. It often involves dropping the transmission pan and replacing the filter, which is integrated into the pan itself.
This job is definitely for the confident DIYer with the right tools and patience. If you’re hesitant, a qualified mechanic or dealership is a wise choice.
Tools and Parts You’ll Need
* Correct
2014 Jeep Grand Cherokee transmission fluid type
: Mopar ZF 8 & 9 Speed ATF (typically 5-7 liters for a pan drop, but check capacity) * New ZF transmission pan with integrated filter and gasket (e.g., ZF S671090255 or equivalent Mopar part) * Torx bit set (T40 for fill plug, T27 for pan bolts) * Torque wrench * Large drain pan (at least 8-quart capacity) * Fluid pump with long hose * Scan tool capable of reading transmission fluid temperature * Safety glasses and gloves * Jack and jack stands (or lift) * Clean rags/shop towels * Brake cleaner or degreaser
Detailed Fluid Change Procedure
1.
Preparation:
* Drive your Jeep to warm up the transmission fluid (as described in the checking section). * Park on a level surface, engage the parking brake. * Safely lift and secure the vehicle on jack stands or a lift, ensuring it’s level. * Place your large drain pan underneath the transmission.
2.
Drain the Old Fluid:
* Locate the drain plug on the transmission pan (often a large plastic plug within a metal plug). * Remove the drain plug and allow the old fluid to drain completely into your pan. This can take 15-30 minutes. * Once drained, reinstall the drain plug temporarily to prevent drips.
3.
Remove the Transmission Pan:
* Carefully remove the numerous T27 Torx bolts holding the transmission pan to the transmission case. Support the pan as you remove the last few bolts, as residual fluid will still be present. * Lower the pan gently, allowing any remaining fluid to drain. * Inspect the old fluid and the magnets in the pan for excessive metal shavings. A fine paste is normal, but chunks indicate a problem.
4.
Clean and Prepare:
* Clean the transmission mating surface on the transmission case. Ensure no old gasket material or debris remains. * Wipe down the area thoroughly.
5.
Install New Pan/Filter:
* Position the new ZF transmission pan (with integrated filter and gasket) onto the transmission case. * Start all the pan bolts by hand to ensure proper alignment. * Using your torque wrench, tighten the pan bolts in a crisscross pattern to the manufacturer’s specified torque (consult your service manual; typically around 8 Nm or 6 ft-lbs). Do not overtighten, as this can strip threads or crack the pan.
6.
Refill the Transmission Fluid:
* Locate the fill plug (T40 Torx) on the side of the transmission. * Using your fluid pump, begin adding the new Mopar ZF 8 & 9 Speed ATF through the fill hole. * Add approximately 4-5 liters initially, then stop.
7.
Initial Fluid Level Check (Engine Running):
* Start the engine. * With the engine running, shift the transmission through all gears, pausing briefly in each (P, R, N, D, etc.). Return to Park. * With the engine still running and the vehicle level, remove the fill plug. * Add more fluid until a steady stream begins to drip out. * Reinstall the fill plug.
8.
Final Fluid Level Adjustment (Critical):
* This is the most critical step. You
must
use a scan tool to monitor the transmission fluid temperature. * Let the engine run, allowing the transmission fluid to warm up to the specified temperature range (86°F to 122°F or 30°C to 50°C). * Once within this range, with the engine still running and the vehicle level, remove the fill plug again. * Add fluid until a steady stream begins to drip out. * Quickly reinstall the fill plug and tighten it to the specified torque. * If no fluid drips out, it was still low. If it gushes out, it was overfilled. Adjust as needed within the temperature window.
9.
Lower Vehicle and Test Drive:
* Safely lower your Grand Cherokee. * Take it for a test drive, paying attention to shift quality. Shifts should be smooth and precise. * Check for any leaks.
Pro Tip:
Always have extra fluid on hand. It’s better to have too much than not enough. Proper disposal of old transmission fluid is also important; many auto parts stores accept it for recycling.
