After I changed my tranny my RPM’s are different. For instance when I’m at 60 in 5th my rpms are at about 1800 and before it was more of 1650 RPM. And when I’m going 70 it’s at 2000 RPM which it wasn’t like before. Can anyone tell me why? I recently had a hose disconnect while driving and got antifreeze everywhere. Could it be that the belt is slipping from the antifreeze? Any input or ideas will help.

What transmission was in it? I remember your previous post about gernading it. Did you have your blown transmission rebuilt,or replace it with a New or used transmission?

I swapped out my TR3650 from my 03 GT and put in a TR3650 from a 01 Bullitt.

I can't say for sure-mainly because I dunno lol.
But a chart from tremec shows a few different 5th gear ratios-which would account for your highway RPM's
