The Nissan Armada was equipped with the RE5R05A and the RE7R01A transmission. The RE5R05A was known for early failure due to the factory radiator allowing engine coolant to enter the transmission through the cooling system, which sometimes can be fixed with a RE5R05A valve body replacement. But they aren’t without their problems though, so let’s look at some of the most common Nissan Armada transmission problems, look at cost estimates and figure out what you can do about them.

Common Nissan Armada Transmission Problems
RE5R05A valve body problems
Although Nissan tends to make very reliable vehicles, the RE5R05A valve body can fail prematurely if the transmission is not maintained properly, and the cooling system design flaw is not addressed in time. Simply rebuilding the valve body typically will not solve problems caused by warping, cracking and damaged bores. The best way around this is to install a remanufactured RE5R05A valve body from a reputable company that has modified it to address the factory design flaws and metal fatigue. To learn more about one of these reman valve bodies, click here. You can also click here to read more about RE5R05A valve body problems.
Transmission won’t upshift from 1-2 or 2-3 – RE5R05A transmission
Problem – The transmission may hesitate or refuse to shift from 1st to 2nd gear, or 3rd to 4th gear. It may also refuse to shift manually.
Solution – These common RE5R05A transmission problems can be caused by a number of things that include dirty transmission fluid, a clogged transmission fluid filter, a failed vehicle speed sensor, direct clutch solenoid valve or inadequate line pressure. The valve body, TCM or direct clutch may have also failed, and/or there may be wiring/communication issues within the CAN bus system.
RE5R05A transmission won’t downshift
Problem – Here are the possible reasons for a no-downshift condition:
5th-4th gear: Transmission fluid level/condition, failed vehicle speed sensor, front band solenoid valve, direct clutch solenoid valve, front brake band, input clutch, inadequate line pressure, failed TCM, failed valve body wiring/communication issues within the CAN bus system.
4th-3rd gear: Transmission fluid level/condition, failed vehicle speed sensor, input clutch solenoid valve, front brake solenoid valve, TCM, valve body, wiring/communication issues within the CAN bus system, inadequate line pressure, failed input clutch.
3rd-2nd gear: Transmission fluid level and condition, failed vehicle speed sensor, high and low reverse clutch solenoid valve, inadequate line pressure, failed TCM or valve body, failed high and low reverse clutch, wiring/communication issues within the CAN bus system.
2nd-1st gear: Transmission fluid level and condition, failed vehicle speed sensor, direct clutch solenoid valve, inadequate line pressure, wiring/communication issues within the CAN bus system, failed TCM, failed valve body, failed direct clutch.
RE5R05A transmission slips or will not engage the following gears:
1st gear: 3rd one-way clutch, 1st one-way clutch, reverse brake, forward brake, direct clutch solenoid valve, valve body, gear damage.
2nd gear: Low coast brake solenoid valve, 3rd one-way clutch, direct clutch, forward brake, valve body failure, gear damage.
3rd gear: 3rd one-way clutch, high and low reverse clutch, forward one-way clutch, forward brake, failed valve body, gear damage.
4th gear: Input clutch solenoid valve, direct clutch solenoid valve, high and low reverse clutch solenoid valve, low coast brake solenoid valve, front brake solenoid valve, input clutch, direct clutch, high and low reverse clutch, valve body failure, gear damage.
5th gear: Front brake solenoid valve, front brake band, input clutch, high and low reverse clutch, gear damage, valve body failure.
Vehicle will not move when in first gear – RE5R05A transmission
Problem – After shifting into Drive, the vehicle may seem to engage first gear but it won’t move.
Solution – This problem may be caused by several things, including a failed torque converter, accelerator pedal position sensor, transmission pump, 3rd one-way clutch, 1st one-way clutch, reverse brake, forward one-way clutch or forward brake.
Poor acceleration when in Drive – RE5R05A transmission
Problem – After placing the gear selector in Drive, the acceleration may be noticeably poor given the throttle position.
Solution – This problem may be caused by several things including; a failed accelerator pedal position sensor, PNP switch, A/T position switch, torque converter failure, transmission pump failure, a failed 1st one-way clutch, reverse brake, forward brake, and/or forward one-way clutch.
Transmission slips/engine races when accelerating – RE7R01A transmission
Problem – If you step on the gas and the engine races without increasing the vehicle speed, the transmission may be slipping.
Solution – If your RE7R01A transmission is slipping, it could be caused by a number of things including; a failing line pressure solenoid valve, low brake solenoid valve, direct clutch solenoid valve, 2346 brake solenoid valve, anti-interlock solenoid valve, input speed sensor, output speed sensor, transmission fluid temperature sensor, wiring/communication issue with the CAN bus system, or valve body issues/failure.
Transmission range switch failure – RE7R01A transmission
Problem – If the transmission range sensor has failed in your Nissan, a number of symptoms can occur including having a difficult time engaging or disengaging Park, the vehicle moves forward when the gear selector is in the P and/or R position, the vehicle moves backward when the shifter is in the D position.
Solution – Check, adjust and/or replace the shift linkage and/or the transmission range switch.

Can I drive with a transmission problem?
If your Nissan Armada can still make it up and down the road, you might say “It’s fine, I’ll just drive it until I can get it fixed”. But that is not always a good idea, depending on the symptoms. You see, there are a lot of (very expensive) moving parts inside of a transmission, and if something isn’t right, continuing to drive with a transmission problem could damage something else.
How often does a Nissan Armada transmission need to be replaced?
The overall lifespan of a Nissan Armada transmission largely depends on how well it was maintained. Factory design flaws also factor into this equation (including the radiator issue that plagued the Nissan RE5R05A in the Pathfinder, Armada, Titan, Frontier and Xterra), along with how/how hard you drive. But on average, we’ve seen the Nissan Armada transmissions last for between 130,000-180,000 miles. A high quality replacement transmission however, can last considerably longer if all of the factory design flaws have been addressed and the vehicle has been maintained.
How are Nissan Armada transmission issues diagnosed?
It is fairly easy to guesstimate what the root cause of your Nissan Armada transmission problems might be, but you won’t truly know unless you have the right tools and experience. A good mechanic or transmission repair center will be able to connect your truck to a computer and find out which diagnostic trouble codes (DTC’s) have been stored. Once they know what to look for, they can perform a visual inspection to verify the problem.
How is a Nissan Armada transmission replaced?
In order to replace your Nissan Armada transmission, the truck has to be lifted from the ground in order to gain access to all of the parts that will need to be unbolted. Then the transmission can be lowered to the ground (typically with a transmission jack), so the new transmission can be installed.

How to Solve Nissan Armada Transmission Problems
Solution A: Buy a Used Nissan Armada Transmission
The quickest way to fix your transmission problems is to simply buy a used transmission or used transmission. These can be found at most junk yards, and they often come with a 30-90 day warranty. However, there’s no way to determine the actual condition of the internal components, so you could be spending a bunch of money to have the exact same problems. Plus, that warranty only covers the transmission if it’s defective, not the labor costs that you’ll have to pay.
Solution B: Buy a Rebuilt Nissan Armada Transmission
Another option would be a rebuilt transmission or rebuilt transmission. A local repair shop will remove your transmission, then install a bunch of new parts during the rebuild. The problem here is, the skills and experience of each transmission rebuilder will vary widely from shop to shop, so you could have problems from something that wasn’t adjusted properly. And the 1-2 year warranty might only cover you at certain transmission repair shops, in a specific geographical area.
Solution C: Buy a Remanufactured Nissan Armada Transmission
Many owners depend on their vehicle to commute and get things done. Their gasoline engines are designed to go 100’s of thousands of miles, so it makes sense to invest in a remanufactured transmission.
