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:
- Confirm the vehicle is a Plug-in Hybrid (PHEV) by checking for a charging port door on the passenger side and 'PHEV' badging.
- Verify the 8th digit of the VIN: '5' for 2018-2020 PHEV (2.0L) or '9' for 2021-2022 PHEV (2.4L).
- Verify the transmission code on the door jamb sticker lists 'F1EKA' or 'F1EKA-1-A1Z'.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- High-voltage insulated safety gloves (Class 0, rated for 1000V AC)
- High-voltage multimeter (CAT III 1000V or CAT IV 600V)
- Engine support fixture/brace
- Transmission jack
- Mitsubishi MUT-III diagnostic scan tool (or high-end bi-directional equivalent)
Budget for these consumables at install:
- Mitsubishi Genuine ATF SP-III (for transaxle gear/clutch chamber)
- Mitsubishi Genuine CVTF-J4 (for front motor cooling chamber)
- Drain plug crush washer (Part #MD000312)
- Fill plug crush washer (Part #MF660036)
- Left and right front CV axle seals
- Engine rear main seal (highly recommended)
- Transmission cooler line flush
What your vehicle’s computers will need after the swap:
What’s involved: Resolver Sensor Calibration, Wet Clutch Engagement Learning, and VIN-specific coding
sources differ: Arm 1 specifies Resolver Sensor Calibration and Wet Clutch Engagement Learning to synchronize motor phases and adapt the parallel-mode clutch. Arm 2 specifies VIN-specific coding and calibration to recognize the replacement transaxle. Both agree a dealer-level scan tool (MUT-III) is mandatory.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Dual-Chamber Fluid Fill: The transaxle has two completely separate fluid chambers requiring different fluids (ATF SP-III for gears/clutch, CVTF-J4 for motor cooling). Mixing or failing to fill both will cause catastrophic failure.
- High-Voltage Safety: Must completely shut down and isolate the high-voltage system by pulling the service plug and waiting 10 minutes before starting work.
- Mandatory Programming: Resolver sensor calibration and clutch engagement learning must be performed with a MUT-III tool or the vehicle will not operate correctly.
- Cooling System Bleeding: All drained cooling circuits for the hybrid electronics and drivetrain must be properly refilled and bled to avoid overheating.
Easy to get right once you know them:
- Ordering for a non-hybrid (gasoline-only) Outlander.
- Using the wrong fluid or filling only one chamber of the dual-chamber system.
- Failing to perform the mandatory resolver and clutch calibrations post-install.
- Attempting the installation without proper high-voltage safety training and equipment.
Not issues with the units on this page — the manufacturer documented these for every transmission of this family, wherever you buy one. Handy for your installer:
🔎 Recommended at install: Refer to corrected special tool descriptions in TSB-20-23-001REV for installing the oil seal.
🔎 Recommended at install: Perform software updates to the PHEV ECU or other control modules to address drivability and EV drive mode availability.

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.
