yeah i agree, just the trans temp seems pointless.

 

The only other gauge possible is a compass.

 

got the 4 mode transfer case installed previously. Today I installed the 4 mode switch and the 2TOD 4x4 control module. Then use forscan to flip the switch and now i have 4x4 auto. tested and it works great. Thanks so much for the write up, I really appreciate it.

 

Would this work on a 2010 Platinum with 3.73 and limited slip diff? It only has 110k miles on the truck so I plan to drive it for many many years to come.

I have 2H, 4H, 4L and I drive the mountains in WA, OR, Idaho and with risk of black ice and surprise snow or freeze at higher elevation - would LOVE to have 4A.

So the items I need I assume are as follows?
- BorgWarner 4417 / CL3Z-7A195-D
- Switch: CL3Z-14B166-DA
- TCCM: CL3Z-7E453-FD
