2008-2012 Mercedes-Benz GL550 Front Signal Acquisition Module SAM Unit 1649004101 Generic

Who would have thought that with a kit from Amazon, a video on the internet, and a little help from the neighbors cat you would be able to rebuild a transmission at home. My 2004 Suburban has been back on the road for several months now. Advise: Getting the top bolts out of the engine is easier if you lower the transmission a lot. Put everything in bags and lay them out in the order they were removed. Reinstall in the reverse order. Make sure the torque converter seats in properly. It should drop in three times. If it doesn't you will be taking everything apart again. Verify the torque converter to flex plate spacing. If your transmission drain plug is stuck, weld a large nut onto it and use an impact wrench (after you have removed the pan and it is not full of oil).

My husbands work car transmission too a poop. My dad told me to order this and he would rebuild it. Worked great! Had everything he needed. Was packaged nicely, and received quickly

Im.still waiting on them

Valve body worked out great.

The valve body feels solid and well‑manufactured, and it fits properly when installed in place of the original unit. Once installed, the solenoid responsiveness improves gear engagement and helps restore consistent shifting behavior, addressing common CVT performance concerns. The unit integrates cleanly with the existing transmission harness and connectors.

Overall, this transmission valve body performs as described, offering dependable operation, precise fitment, and reliable shifting performance. It’s a practical replacement option for maintaining or restoring smooth CVT function in compatible Nissan Sentra and Versa vehicles.
