The RE5R05A is Nissan's 5-speed automatic that appeared behind their larger V6 and V8 engines from the early 2000s through the mid-2010s. It's found in the Pathfinder, Armada, Titan, Xterra, Frontier with the V6, Infiniti QX56, QX80, and the FX and EX series. If you work on any volume of Nissan or Infiniti, you're going to see this transmission. It's worth understanding it well because diagnosis mistakes on this unit are expensive for your customer and your credibility. The RE5R05A is a traditional hydraulically controlled 5-speed automatic with electronic solenoid control through a separate transmission control module. It's not a CVT — that's important because a lot of the customer confusion and online misinformation about Nissan transmissions blurs the line between CVT-equipped Altimas and Sentras and the conventional automatic RE5R05A in the larger platforms. When a Pathfinder or Titan owner says "my Nissan transmission is acting up," the first clarification your service writer needs to make is whether it's a CVT or a conventional automatic, because the diagnosis and service procedures are completely different.

First Step on Any RE5R05ALine pressure diagnosis on the RE5R05A is the most important first step in any shift quality complaint. Front pump wear vs solenoid body failure produces almost identical drivability symptoms, and pressure data is the only reliable way to differentiate them before you commit to a repair path.
