2007–2009 Mercedes-Benz GL320 ML320 R320 Frontsignalerfassungsmodul SAM-Einheit 1649004101

Arrived packed well, pre-programmed, and worked perfectly for my application. No additional steps were required after installation beyond a basic relearn. Great price, program is accurate, fully compatible, correct connections, OEM-like.

Quick shipping, responsive messaging and the TCM worked like a champ with no issues in my 2009 Mazda 3. I recommend ordering shipped directly from this “Revolve Plug N Play” seller. Gave them my VIN number via messaging. Very glad the 3 is back up, shifting smooth again and running with no warning lights.

It worked right out of the box

I had tried another TCM module from Amazon seller that was able to ship it to me, but that one was not preprogrammed. Even when it said pre program in their description, but it did not work and It gave error codes. So I bought another TCM #2, from FleaBay that was supposed to be already programmed, but that one was even worse than the first TCM I bought from Amazon. 2nd TCM from ebay gave hard clunking when shifting to reverse. and it cause even more error codes than my OEM TCM! So I found this seller here. Thank goodness REVOLVE SAVE MY DAUGHTER CAR! I Purchased this TCM through this seller and their partner, Because Amazon won't ship it to me. But this seller will work with you and provide assistance and communication for alternatives. Also they can program the TCM with your VIN number. That really help your car's computer communicate with your car's transmission and other code issues, like non stop running radiator fan always on high blast. That's one of the symptoms for the TCM error code and hard shifting. The AT LIGHT, TRACTION LIGHT AND CHECKED ENGINE LIGHT WENT OFF. I CLEARED IT WITH OBD SCANNER AND ALL SHIFTING GOOD AND SMOOTH! NO CLUNKING OR OTHER ERROR CODES. I would buy from this seller again, only if Amazon changes their shipping policy. Just remember to provide your VIN so they can program it to your TCM model number. TCM MODEL L539189E1H PROGRAMMED TO L539189E1J it worked for me. THANK YOU AGAIN REVOLVE! For referral. 5 ⭐

Was very happy with my purchase. Works great.
