Ask Smithy Xtras Hyundai Sonata clunk

...

My 2009 Hyundai Sonata 2.4-litre has a severe clunk on change down at 38 km/h. At first the dealer said there was no fault, next they said they did not have the tools to test it, finally they reset the solenoid, which worked great for week and a half, but the clunk is now back and worse than ever. What can I do?

It does sound like a problem with a solenoid. Most dealers would send cars with auto transmission problems out to a transmission specialist rather than fix them in-house, so find out from the dealer where they send their problem cars and consult that specialist. You could also consult an auto transmission specialist to get an independent opinion.
