If your EASA TR is current then you can get it put on your FAA cert without any training or check ride. Everything you need to know is on the Internet, start by looking through the ACs.
I will point out that getting the TR on your FAA certificate is pointless: You already have an ATPL, so the only reason you'd need an FAA certificate is to work in the US. If you manage to get a job in the US it won't be on a 757/767 and they'll pay for your ATP anyway.
