After transmission replacement, Nissan/Infinity vehicles equipped with the RE5R05A may exhibit a complaint of gear-ratio-error codes and/or incompatibility issues with the transmission control module, as in a trouble code for a missing manual shift switch when the vehicle you are working on does not use a manual shift switch.

The cause may be that when the transmission was exchanged, the TCM, which is internal to the transmission on most models, was not compatible with the shifter assembly in the vehicle in which it was installed. In figures 1 through 3 you can see that there are three different gear-ratio charts and planetary tooth counts available,

and figures 4 and 5 show the locations of the planetary components. You must take care to ensure that you use the correct planetary assemblies in the vehicle being repaired.and figures 4 and 5 show the locations of the planetary components. You must take care to ensure that you use the correct planetary assemblies in the vehicle being repaired.

To correct this condition, identify the original transmission that you are repairing by the tag shown in Figure 6. Use this information to identify a core that you may be disassembling for used planetaries and/or a used TCM, and ensure that it is compatible.

Refer to Figures 7a, 7b for model identification, which will include a planetary ratio chart and vehicle application for two- and four-wheel drive. ATSG highly recommends counting all planetary assemblies being replaced to verify that the same ratios are going back into the transmission.

The RE5R05A is used behind many different-size engines, and there are components that are matched to the engine size as shown in figures 8-10, which show correct component application. The turbine-shaft length, pump-stator length and torque-converter build height are all matched. Any incorrect combination of these pieces can cause numerous complaints.

Refer to Figure 8 for turbine-shaft dimensions and application.

Refer to Figure 9 for stator-shaft dimensions and application.

Refer to Figure 10 for torque-converter build-height dimensions and application.
