Tundra transmission lines?

Ok so my mechanic just put a new engine in my 03 tundra sr5 v6. He said that the transmission lines are rotted and need to be replaced. I have searched everywhere online for “transmission lines” and I can’t find anything. I’ll be honest I’m a novice with all of this. Can someone provide me with a link to what I am looking for? He said I need to replace both. I’m just trying to get an estimate for what the parts will cost. Thanks

 

"Rotted"...I love professional assessments.

This is what I could find, but part descriptions appear wankered to me. The right pricing is probably in there somewhere. Suggest you contact @Roman for best information:

Thanks for the info! Hopefully he will see that you tagged him!
