It's a very reliable transmission and there is no need to worry.
You realize a turbo systems is one added spinning part and 2 oil lines and that's about it right? Nothing complex. And they don't make the engine work harder, they increase the ability of the engine by supplying more air, nothing more.I'm not a fan of turbo. Guy next to me has a turbo vehicle in his driveway and its turbo is broken. It will take $3K to fix it and trade-in (with working turbo) is $900. Not worth fixing and cannot trade it in. So, his vehicle just sits there.... Like I said, I'm not a fan of little engine engines and turbo tops - to force them to work harder... Way too many moving / spinning parts - that increase risk of breakage and higher repair costs. But that's me.....
