9-Speed Automatic Transmission Assembly for 2017-2019 Fiat & Jeep • 500X, Cherokee, Renegade - Front

A quick look at your own vehicle makes sure the right transmission shows up:

• Verify the 8th digit of the VIN is 'B' (designating the 2.4L Tigershark engine).
• Confirm the vehicle is strictly Front-Wheel Drive (FWD / 4x2) with no AWD/4WD selector knob.
• Confirm the engine is a 2.4L 4-cylinder.
• Locate the barcode label on top of the original transmission case and verify part number 68311487AA or 68311487BA.

What the install really takes — plan and budget with confidence:

Special tools this job needs:

• Engine support bar/fixture
• Transmission jack
• Mopar Transmission Dipstick Tool (P/N 10323A) or 175mm measuring rod
• Bi-directional scan tool (wiTECH 2.0, Snap-On, or Multiecuscan)

Budget for these consumables at install:

• Mopar ZF 8 & 9 Speed ATF (or equivalent meeting ZF Lifeguardfluid 9 specifications)
• Transmission filter (internal, non-serviceable unless splitting case, but outer pan gasket/seal should be replaced if opened)
• Torque converter seal / input shaft pump seal (Mopar P/N 4752960AA)
• Solvent-based transmission cooler line flush (e.g., Lubegard Kooler Kleen)

What your vehicle’s computers will need after the swap:

What’s involved: PROXI Configuration Alignment and TCM Quick Learn / Solenoid Learn

A PROXI alignment is required to marry the transmission electronics to the BCM/PCM if modules are mismatched. A TCM Quick Learn is mandatory to calibrate the valve body solenoids to the internal clutches; skipping this causes immediate internal damage.

Pro tips for a smooth first start-up — hand them to whoever does the install:

• Torque Converter Seating: Must slide back and click three distinct times. If not fully seated, bolting the bellhousing tight will crush the internal oil pump gears, destroying the unit.
• Fluid Level Check Procedure: No traditional dipstick. Must check level with vehicle perfectly level, engine idling in Park, fluid temperature between 122°F and 140°F (50°C to 60°C) using the special Mopar dipstick tool.
• Subframe Realignment: Front subframe must be lowered; mark its position before removal to prevent suspension misalignment and off-center steering.
• Cooler Line Contamination: Solenoids are extremely sensitive to microscopic debris. Leftover metal shavings from a previous failure will clog the replacement unit's solenoids immediately.

Easy to get right once you know them:

• Using the wrong fluid (universal ATF instead of Mopar ZF 8 & 9 Speed ATF / ZF Lifeguard 9).
• Skipping the PROXI alignment and TCM Quick Learn procedure.
• Ordering the wrong drivetrain version (mistaking AWD for FWD).
• Forcing the bellhousing bolts when the torque converter is not fully seated.
