Tremec Identification

[bowtie_nut]

I am looking to buy a tremec transmission tko600. I have someone that is wanting to sell me his, but I would like to make sure that it is a tko600. There is a tag on the passenger side of the transmisson with the following info on it.
TR 3550-12 KF12
TCET5009 AC 0042

Can anyone verify what the transmisson is? I would hate to buy it and find out later that it is not what I wanted.

TCET5009 identifies it as a TKO 600.

I was a little concerned with the TR3550 on the tag. I thought maybe it was the previous generation which was a TR3550.
