  1. Hans Dekkers –

    I run https://mercedesjellinek.com in Cranbrook, BC, Canada, and was handed a beautiful but broken E55 AMG. The 722.6 transmission clutch packs were gone. Our client found a replacement transmission from an identical car, and we did a transmission change. Limp mode remained. Contacted TJ here at MK Ultra Electronics. He identified that the existing TCU had the wrong part number for the car, which my check in the Mercedes EPC confirmed. We purchased a new TCU for the exact VIN and now have a smooth-as-butter shifting and performing AMG back. Excellent support, and an excellent product. Super diligent service. Highly recommended.

  2. Allen Kroliczek (verified owner) –

    Service was absolutely spot on – highly recommend using MKUltra. We had a G500 with a TCU that was stuck in limp and unable to read output speed. Anyone familiar with the W463 TCU’s knows they’re trouble to source.

    We got our replacement in a few days, plugged it in, and the thing is shifting like butter again. 10/10 service. I’ll use these guys over and over again at our shop here in Wauconda!

    Thanks again!
    Allen
