Transmission cooler line fittings, different sizes?

[th3 shifty]

Are there 2 different line cooler fitting sizes on the trans cooler? I have brand new lines for the cooler, and it seems one fits in a bit loose compared to the other. Leads me to believe that there are 2 different fitting sizes,

Can anyone confirm this or have knowledge otherwise? If so do you have parts numbers?

I bought 2 of these

Could be the manufacturer. (counterfit) Or possibly previous repair. All I've seen are the same on 4L60E. Check length from ISO flare to end of tube also.

Yeah to clarify, it’s loose going in and out not side to side.. just didn’t want to start the truck and have a nice leak going on
