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 vehicle is Front-Wheel Drive (4x2) and does not have a rear driveshaft or rear differential.
- Verify the vehicle has a manual transmission with a clutch pedal.
- Verify the 8th digit of the VIN is 'H' (designating the 1.4L MultiAir Turbo engine).
- Verify the 5th digit of the VIN represents a FWD configuration (typically 'A' or 'C' for Renegade).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine support bridge/bar
- Transmission jack
- Pressure bleeder
- Triple-square (XZN) and Torx socket sets (including E-Torx E18)
- Hydraulic clutch line disconnect tool
Budget for these consumables at install:
- Mopar C Series Manual & Dual Dry Clutch Transmission Fluid (Tutela Gearforce 75W, Fiat 9.55550-MZ6 spec)
- New Clutch Kit (clutch disc, pressure plate, and concentric slave cylinder/release bearing)
- New Left and Right CV Axle Output Seals
- Engine Rear Main Seal
- New or Resurfaced Flywheel (Dual-Mass Flywheel)
What your vehicle’s computers will need after the swap:
What’s involved: none
This is a conventional manual transmission with no complex electronic controls requiring programming or security re-marriage to the vehicle's ECU.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- The Concentric Slave Cylinder (CSC) Bleeding Nightmare: Standard pump-and-hold bleeding often fails; a dedicated pressure bleeder at the reservoir is highly recommended.
- The Starter Motor Stud Trick: Temporarily removing the starter motor mounting stud from the block before sliding the transmission on creates crucial clearance.
- Subframe Alignment: The front subframe must be perfectly aligned with its chassis dowels upon reinstallation to prevent steering and wheel alignment issues.
- CV Axle Seating: Ensure both front CV axles are pushed in until the internal snap rings click into the differential to prevent them from popping out under load.
- Shared Brake/Clutch Fluid Reservoir: The brake fluid reservoir is partitioned internally; ensure it is topped off with correct fluid after bleeding the clutch.
Easy to get right once you know them:
- Buying for an AWD (4x4) Vehicle: This FWD unit lacks the mounting bosses and output shaft configuration required to bolt up the Power Transfer Unit (PTU).
- Reusing the Old Concentric Slave Cylinder: Used slave cylinders almost always leak shortly after being disturbed, requiring another 8+ hour labor job to replace.
- Using Generic Gear Oil: Standard 75W-90 or generic synchromesh fluid ruins shift quality and damages C635 synchronizers.
- Confusing Manual with DDCT Automatic: This manual transmission cannot be used if the vehicle does not have a clutch pedal.
- Ordering for the Wrong Engine: Attempting to install this on a 2.4L Tigershark engine, which was only paired with a 9-speed automatic.
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: Replace the internal concentric slave cylinder (CSC) and master cylinder concurrently with the transmission swap.
🔎 Recommended at install: Use exact factory-recommended synthetic fluid (Mopar C Series / Tutela Gearforce 75W).
🔎 Recommended at install: Verify bearing integrity before installation; donor unit verified at 35,945 miles.

Policies, in plain English.
Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- 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
120-Day Warranty
This part includes a 120-day warranty.
- 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
- Warranty covers defects — not installation errors, misuse, or damage after installation
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.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
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.
