i own a hundai santa fe 2007 model crdi automatic transmission tiptronic with a 2.2 disel engine.

i need help in looking for a computer box since everytime i have the computer reset it runs perfectly well until it reaches 3000rpm and it locks on 3rd gear and dosent shift up anymore.

at first i thought it was just the solinoid valves so i had them replaced but the same problem still keeps happening.

so the shop told me that there is a problem with the computer box.

so please if anyone has or knows where i can find a computer box for my santa fe please help me out.

thank you

this is the picture of my computer box.
