As the title states I’m looking for a detailed tutorial/guide to remove my Sst so I can send it in to be repaired.

I’d be grateful if somebody could point me in the right direction.

Thanks in advance.

 

evoscan-dot-com has the complete service manual from Mitsubishi along with other resources. It's not much different than removing any other trans tbh. Also, there are some video's on youtube from folks who have done it.
