Know This Transmission Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this transmission family:
A quick look at your own vehicle makes sure the right transmission shows up:
- Verify the vehicle is a 2017-2018 Jeep Cherokee with the 2.4L engine.
- Confirm the vehicle has a 4x4 system with a 2-speed transfer case (Active Drive II, featuring a '4WD Low' setting on the selector dial).
- Confirm the vehicle has a 3.73 final drive ratio.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Mopar Tool 10323A (or equivalent 948TE dipstick tool)
- OBD2 scan tool capable of reading real-time transmission fluid temperature (TFT) and performing Chrysler TCM Quick Learn (e.g., wiTECH)
Budget for these consumables at install:
- Mopar 8 & 9 Speed ATF (or ZF Lifeguard 9)
- Torque converter input shaft seal / front pump seal
- Axle seals
- Transmission pan gasket (if pan is serviced)
- Professional cooler-line flush chemical/service
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn (Quick Learn) and potential TCM software flash
A Transmission Quick Learn procedure is mandatory after installation using a dealer-level scan tool (like wiTECH) to clear adaptive memory and recalibrate shift solenoids. Failure to perform this will result in poor shift quality, slipping, or immediate limp mode.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Ensure the torque converter is fully seated (typically three clicks) before bolting the transmission to the engine to avoid cracking the front pump.
- PTU Alignment and Splines: Apply high-quality, high-temp anti-seize or spline grease to the output shaft and PTU input splines to prevent rust and stripping.
- Fluid Level Check Procedure: The vehicle must be level on a lift, left front wheel removed to access the fill plug, and fluid level checked using Mopar Tool 10323A with the engine idling in Park and fluid temperature strictly between 122°F and 140°F (50°C to 60°C).
- Subframe Alignment: Dropping the front subframe is required; mark alignment or use alignment pins to keep steering and suspension centered.
Easy to get right once you know them:
- Using the wrong fluid (such as standard ATF+4 or universal fluids) instead of genuine Mopar 8 & 9 Speed ATF or ZF Lifeguard 9.
- Skipping the TCM Quick Learn adaptive reset procedure, leading to immediate harsh shifting and limp mode.
- Forcing the bellhousing bolts to pull the engine and transmission together when the torque converter is not fully seated, cracking the pump.
- Neglecting to flush the transmission cooler and lines, which recirculates debris from the failed unit and voids the warranty.
- Buying a FWD or single-speed AWD version of the transmission for a 4x4 vehicle requiring the 2-speed transfer case.

- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance

Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.

Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
