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 4x2 (two-wheel drive) and does not have a transfer case or front driveshaft.
- Verify the 4th digit of the VIN is 'A' (Frontier) and the engine is the 4.0L V6 (VQ40DE).
- Check the radiator for signs of SMOD (pink milkshake fluid).
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Heavy-duty transmission jack
- Torque wrench
- Fluid pump and fill adapter / charge pipe tool
- Scan tool capable of reading real-time transmission fluid temperature and performing adaptive relearns
Budget for these consumables at install:
- Nissan Matic-S ATF (approx. 10.9 to 12 quarts for full dry fill)
- Transmission Filter Kit (internal filter/strainer and new pan gasket)
- Torque Converter / Front Pump Seal
- Transmission Cooler Flush aerosol
What your vehicle’s computers will need after the swap:
What’s involved: TCM Adaptive Relearn / VIN-Specific Programming
The TCM is integrated with the valve body and contains adaptive shift strategies. A TCM adaptive relearn procedure must be performed using a compatible professional-grade scan tool (like Nissan's CONSULT tool) to ensure smooth shifting. Alternatively, the original working valve body and TCM assembly can be swapped into the replacement transmission to avoid programming.
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 (2-3 distinct clicks/drops) before bolting to the engine. Failure to do so will crack the front pump gear, instantly ruining the transmission.
- Radiator Replacement / Bypass: If the original transmission failed due to SMOD, the radiator must be replaced. Simply flushing it is not enough.
- Bellhousing Dowel Pins: Ensure alignment dowel pins are in the engine block and not stuck in the old transmission to prevent misalignment and rapid wear.
- Fluid Level Check Procedure: This transmission does not have a traditional dipstick on some models. It must be filled from a port on the bottom of the pan and checked with the engine running and fluid temperature between 104°F and 176°F.
Easy to get right once you know them:
- Reusing a contaminated radiator after an SMOD failure, which immediately destroys the replacement transmission.
- Ordering a transmission from a 4x4 Frontier, Titan, Pathfinder, Armada, or Xterra assuming they are all the same RE5R05A.
- Using generic multi-vehicle ATF instead of genuine Nissan Matic-S, causing torque converter shudder and harsh shifting.
- Improper torque converter installation leading to a cracked front pump on startup.
- Skipping the cooler line flush, allowing old debris to contaminate the new valve body.
- Using standard red shop rags that leave tiny cotton fibers ('Red Death') which clog the solenoids and valve body passages.
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 radiator and thoroughly flush the cooler lines before installing the replacement transmission.
🔎 Recommended at install: Repair or replace the internal conductor/lead frame of the TCM or repair broken connection pins where the solenoid attaches to the TCM board.
🔎 Recommended at install: Replace torque converter or ensure proper fluid maintenance.
🔎 Recommended at install: Replace failed O-ring on the EVAP vent control valve (not a transmission issue but causes Check Engine Light).

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.
