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 has a 6-speed manual transmission (clutch pedal present).
- Confirm the engine is the 1.6L Gamma G4FD engine (not the 2.0L engine). Check the emissions label under the hood.
- Verify the transmission code on the barcode label or stamped on the top of the bellhousing reads M6CF1.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bar/fixture
- Transmission jack
- CV axle popper/pry bar
- Clutch alignment tool
- Torque wrench
Budget for these consumables at install:
- API GL-4 SAE 75W-85 (or 75W-90) gear oil (approx. 1.9 to 2.0 quarts / 1.8 to 1.9 liters)
- New clutch kit (clutch disc, pressure plate, and release bearing/concentric slave cylinder)
- Pilot bearing/bushing
- Left and right CV axle shaft seals
- Engine rear main seal (highly recommended)
- High-temp clutch spline grease
What your vehicle’s computers will need after the swap:
What’s involved: none
This is a fully mechanical manual transmission. It does not have a Transmission Control Module (TCM) and requires no electronic programming, VIN-specific calibration, or security remarriage.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Concentric Slave Cylinder (CSC) Bleeding: Must thoroughly bleed the clutch hydraulic system after installation to prevent a spongy pedal or shifting issues.
- Subframe Alignment: Replacing this transaxle requires lowering or removing the front subframe. Ensure it is perfectly aligned with body dowels to prevent steering wheel misalignment.
- Input Shaft Spline Lubrication: Apply a very light coat of high-temp clutch spline grease. Too much will ruin the clutch disc; too little causes rough shifting.
- Axle Seal Damage: Be extremely careful not to nick or tear the rubber inner lip of the axle seals when inserting CV axles.
- Hidden Bellhousing Bolt: One bolt high up behind the engine is difficult to access and may require a long extension and swivel socket.
Easy to get right once you know them:
- Mistaking a slipping clutch for a blown transmission.
- Reusing the old clutch disc, pressure plate, or concentric slave cylinder.
- Using the wrong gear oil (using API GL-5 instead of API GL-4, which damages brass synchronizers).
- Not using a clutch alignment tool, leading to forced installation that damages the input shaft or clutch disc.
- Forgetting to replace the engine's rear main seal while the transmission is removed.
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: Lubrication or component replacement of the clutch release fork or input shaft bearing area.
🔎 Recommended at install: Perform standard clutch replacement instead of replacing the entire transmission.
🔎 Recommended at install: Design characteristic; driver must adapt to avoid excessive slipping and premature wear.
🔎 Recommended at install: Replace the worn input shaft bearing.

- 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

- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included

Your pre-purchase interview reviews these exact terms with you before anything is charged.
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.
