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 8th digit of the VIN is '2' (designating the 4.2L V6 engine).
- Physically confirm the vehicle is a 4x2 (RWD) model with no front differential or transfer case.
- Check the driver's side door jamb Safety Compliance Certification Label under the 'TR' column for code 'A'.
- Inspect the metal identification tag on the driver's side of the transmission case to match the 4R70E codes.
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- torque converter depth gauge or straightedge
- transmission jack
- torque wrench
- socket and wrench set
- tool for disconnecting fuel/cooler lines
Budget for these consumables at install:
- Motorcraft MERCON V ATF
- Transmission filter (e.g., Motorcraft FT-105)
- Pan gasket
- Torque converter / front pump seal
- Transmission cooler flush agent
What your vehicle’s computers will need after the swap:
What’s involved: TCM/PCM Adaptive Shift Strategy Relearn
No VIN-specific programming is required. It is recommended to perform a Keep Alive Memory (KAM) reset by disconnecting the battery for 30 minutes or using an OBD2 scan tool, followed by an adaptive learning drive cycle.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Torque Converter Seating: Must be fully seated (three distinct clicks/drops) to avoid cracking the front pump gear upon bellhousing bolt tightening. Verify seating depth is at least 1 inch recessed from the bellhousing face.
- Bellhousing Alignment Dowels: Ensure both engine block alignment dowels are clean, undamaged, and in place to prevent rapid wear on the front pump bushing and seal.
- Cooler Line Flushing: Thoroughly flush the transmission cooler and lines to prevent old debris from contaminating the replacement unit.
- The 'Mystery Plug' in the Pan: A small yellow plastic plug with an O-ring floating in the pan is a factory assembly plug and does not indicate a problem.
- Fluid Fill Procedure: Do not assume the transmission is full. Add 5-6 quarts initially, start the engine, cycle through gears, and top off while warm and running.
- Flexplate Inspection: Inspect the flexplate for cracks around the crankshaft hub and starter ring gear while the transmission is out.
Easy to get right once you know them:
- V8 vs. V6 Compatibility: Assuming all 4R70E transmissions are identical. V6 models use a small block pattern, while V8 models use a Modular V8 pattern.
- 4x4 vs. 4x2 Drivetrain: Ordering a 4x4 transmission for a 4x2 truck (or vice versa) without realizing they have different output shafts and tailhousings.
- Using the Wrong Fluid: Using Mercon LV, ULV, or generic fluids instead of the strictly required MERCON V.
- Reusing the Old Torque Converter: Reusing a contaminated torque converter, which will recirculate debris and void the warranty.
- Breaking the Pump: Failing to fully seat the torque converter before tightening the bellhousing bolts.

- 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

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

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

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.
