Potential solution to Kia Sportage 7 speed DCT gearbox judder?? Posted on March 19, 2024 by admin This “trick” was used in the past on the earlier Kia Souls that had a DCT gearbox. I have no idea if it forces the gearbox ECU to rediscover the bite points or if it just clears some glazing off the plates but it does seem to help.
