Nissan Pathfinder Transmission Problems & Solutions

Sold from 2005-2012, the R51 Nissan Pathfinder was the 3rd generation of Nissan’s best-selling SUV. To make it stand out in the crowded midsize sport-ute segment, designers ditched the suave lines of the previous version, in favor of a tougher, more truck-like appearance. Then they switched the Pathfinder from unibody to body-on-frame construction, which made the new truck far more capable, both on and off the road. Buyers could choose from a 266-hp 4.0L V6, or the torque-tastic 5.6L V8 from the Titan pickup (310-hp). Both engines were backed by the Nissan RE5RO5A transmission, which used 5 forward gears to improve fuel economy, without reducing performance. In terms of towing capacity (up to 6,000 lbs), and off-road prowess, few midsize MomUV’s could touch the 2005-2012 Nissan Pathfinder. But a design flaw in the radiator often led to early gearbox failure, and the automaker was eventually forced to give many owners a remanufactured Nissan Pathfinder transmission.


Common Nissan Pathfinder RE5RO5A Transmission Problems

Premature failure due to contaminated transmission fluid

The transmission cooler passages on the (2005-2010) OEM Nissan Pathfinder radiator are known to develop cracks, which allows engine coolant to mix with the transmission fluid as it flows through the cooling system. As the antifreeze circulates back through the gearbox, it causes rapid, catastrophic wear to the transmission clutch seals and other internal components. The only solution to this problem is a remanufactured Nissan Pathfinder transmission. You could get a rebuilt Nissan Pathfinder transmission, but many transmission repair shops can miss problems that will be automatically addressed during the remanufacturing process.



The transmission has to work much harder when you’re towing a trailer, and that additional strain/friction causes the transmission fluid to heat up. On most vehicles, the OEM transmission cooler can remove enough heat to prevent internal damage. But given the Pathfinder’s rather “challenged” factory radiator design, you might want to consider installing an auxiliary transmission cooler (especially if you do a lot of towing). Because overheating your Nissan RE5RO5A transmission will cause severe damage to the transmission bands, clutches, valve body and torque convertor. And none of that is cheap to fix.


Hard shifting and slipping

On the Nissan RE5RO5A automatic transmission, hard 2nd-3rd shifts can often be traced back to a faulty clutch pack. And slipping between 4th-5th gear can be caused by worn bands, a bad solenoid, or even the wrong type of transmission fluid. Having your transmission serviced regularly, will help to extend the service life of these parts. But if you’re already experiencing these problems, one of our reman Nissan RE5RO5A transmissions can get you back on the road, and the 3-year/Unlimited Mile Warranty will protect your wallet from future repairs.

How to Solve Nissan Pathfinder Transmission Problems

Option 1: Buy a Used Nissan Pathfinder RE5RO5A transmission

Although getting a used Nissan RE5RO5A transmission is the cheapest option, you need to think about the long-term. There’s no way to be certain of the actual condition of vital internal components, or the expected service life on a used Nissan Pathfinder transmission. And once that 30-90 day junkyard warranty is over, you’ll have to pay to fix that transmission if/when it breaks.


Option 2: Buy a Rebuilt Nissan Pathfinder RE5RO5A transmission

The value of a rebuilt Nissan Pathfinder transmission is ultimately determined by the skill of the person rebuilding it. Each transmission shop has different procedures and different technicians. So the quality and the service life of a rebuilt transmission will vary from place to place. Plus, the typical warranty period is just 1-2 years, and your coverage may be restricted to a specific transmission shop franchise or location. Which will do you absolutely no good, if your gearbox suddenly decides to explode while you’re visiting Grandma…500 miles from the nearest XYZ Tranny Express.
