Engine: VQ35DE 3.5L V6

Therefore, customers should compare this actual transmission with their original unit before purchasing.

Nissan 350Z VQ35DE 3.5L Transmission

The 2003–2006 Nissan 350Z was available with the VQ35DE 3.5L V6 engine and a 5-speed automatic transmission.

For this listing, the primary product relationship is:

2003–2006 Nissan 350Z → VQ35DE 3.5L → RE5R05A / JR507E → 5-Speed Automatic → RWD

However, Nissan used different transmission and electrical configurations during production. Therefore, vehicle year and engine size alone should not be used to determine compatibility.

Instead, compare the original transmission with Item 46253 before ordering.

Infiniti G35 Automatic Transmission

This transmission also targets compatible Infiniti G35 3.5L VQ35DE RWD automatic applications.

As with the Nissan 350Z, complete transmission identification is important. In particular, compare the electrical connectors, sensors, solenoids, valve body configuration, bellhousing, torque converter, mounts and output configuration.

Most importantly, this listing targets RWD applications. Therefore, do not automatically use this transmission for an Infiniti G35x AWD application.

Additionally, later G35 applications equipped with different engine or transmission configurations should be verified separately.

RE5R05A / JR507E 5-Speed Automatic Transmission

The RE5R05A is a conventional 5-speed automatic transmission family used in several Nissan and Infiniti RWD applications. The related Jatco family is commonly identified as JR507E.

However, the RE5R05A/JR507E family was used across multiple vehicles and configurations. As a result, the family designation alone does not guarantee interchangeability.

Before ordering, verify the original transmission identification and compare the case, bellhousing, electrical connectors, sensors, solenoids, valve body, torque converter, mounts, cooler fittings and output configuration.

Furthermore, compare the actual Item 46253 photographs with your original transmission.

Nissan 350Z Transmission Fitment

This JDM automatic transmission primarily targets compatible:

2003 Nissan 350Z 3.5L VQ35DE RWD Automatic

2004 Nissan 350Z 3.5L VQ35DE RWD Automatic

2005 Nissan 350Z 3.5L VQ35DE RWD Automatic

2006 Nissan 350Z 3.5L VQ35DE RWD Automatic

It may also fit compatible 2003–2006 Infiniti G35 VQ35DE 3.5L RWD automatic applications when the original transmission configuration matches.

Nevertheless, production differences may exist. Therefore, always verify the original transmission before purchasing.

350Z Automatic Transmission Installation

Proper installation is essential when replacing an automatic transmission.

First, thoroughly flush the transmission cooler and cooler lines. A failed transmission can leave contaminated ATF, clutch material and metal particles inside the cooling circuit.

Consequently, contamination left inside the cooler can immediately circulate through the replacement transmission. Therefore, make sure the cooler and lines are clean before startup.

Next, inspect accessible transmission seals. In particular, inspect the torque-converter/front seal and output seals.

Additionally, confirm whether the torque converter is included with Item 46253.

If included, make sure the torque converter is fully seated before mating the transmission to the engine. Most importantly, never use the bellhousing bolts to force the transmission and engine together.

Transmission Fluid and Final Setup

Use the correct Nissan automatic transmission fluid specified for the exact vehicle application and current Nissan service information.

After installation, verify the correct fluid level according to the applicable factory procedure.

Then, scan the vehicle for transmission-related diagnostic trouble codes. In addition, perform applicable reset, initialization or learning procedures when required.

Afterward, complete a controlled road test. Verify Reverse and Drive engagement, all five forward shifts, downshifts and torque-converter lockup.

Furthermore, inspect the transmission for fluid leaks, delayed engagement, slipping, abnormal noises or warning lights.

Finally, keep the original transmission until Item 46253 has been successfully installed and road-tested.
