SI-EVT Transmission Question

525 Views 6 Replies 5 Participants Last post by  Dave Z
All Par Nation...I was hoping you could help me answer a question I had.

Is the SI-EVT Transmission that is produced at Tipton Transmsision plant in Indiana and used on the Pacifica PHEV (Windsor Assembly) the same transmission that is being used in the Grand Commander PHEV (China only vehicle). If yes, does Tipton produce this transmission and send it to China for Grand Commander assembly plant?

Both the Pacifica and Gran Commander are FWD SI-EVT's, but the Pacifica PHEV uses a 3.6L V6, while the Grand Commander uses the 2.0L I4.

Also...Pacifica PHEV is FWD only, while the Grand Commander is available in FWD or AWD, which leads me to believe that these are two different transmissions. Curious why Stellantis would have two similar low-volume applications for FWD PHEV platforms.

The SI-EVT seems to use the sales code DFQ for both vehicles, but with different part numbers, so it seems that they probably are the same, just with different cases to mount differently between one and the other, if not because different part numbers are sold elsewhere in the world.
Also, light research showed me a picture that is a 3D rendering of the Grand Commander's hybrid drivetrain without any driveshaft. Judging by how many articles report the GC's PHEV only having 2 electric motors, and with the SI-EVT having 2 motors within it, it's safe to say that the Grand Commander PHEV is only a FWD hybrid.
