Good Afternoon Team!

Today, as i was exiting the off-ramp onto the highway, I had just gotten into 4th and sort of "got on it" a bit to get up to speed quicker and my RPMs took off, but my car didn't.
I let off the gas and the RPMs dropped back down and seemed to "catch". I was then able to accelerate slowly up to my desired speed, but if i "get on it" so-to-speak, my RPM's take off and my car doesn't accelerate along with the RPMs.

Some helpful information, I believe i do have a transmission fluid leak, but i have been keeping an eye on the level.
The issue seems to remain even when i have the correct amount of transmission fluid.
Is my clutch slipping or something like that?

Let me know what ya's think.
Thank You in advance.

 

Yep, that is the sign of worn clutch

 

A leak from input shaft seal or rear main oil seal has potential to contaminate the clutch with oil.
