Help Needed: P0756 code

I have a 2006 Sorento 3.5 4x4 EX (old body style) with 239,000 miles, and it’s showing a P0756 code for “Shift Control Solenoid Valve B Performance or Stuck Off.” Does anyone know how to find the part number for this?

That P0756 code is a common gremlin, often pointing to a stuck shift solenoid. To pinpoint the exact part you need, you’ll want to visit a Kia dealership armed with your VIN number.

They’ll have the most accurate information to match that solenoid to your specific Sorento.

Don’t worry, replacing it is usually straightforward, but if you’re not a DIYer, a trusted mechanic can handle it.

Regular transmission fluid and filter changes can help prevent these issues in the future.


I would have this properly diagnosed and/or fixed by a professional. You don’t seem to have done this kind of work before, and if you don’t feel confident doing it, you might damage the transmission. If I were to try any additional fixes, I would definitely try a spill and fill or flush.
