Is my Transmission Slipping?

Default Is my Transmission Slipping?

I need to pick your brains again. My transmission engages just fine in Drive and Reverse and it takes off normal. However, I have noticed than when I am going highway speeds, 60-70, and I let off the gas the transmission goes into a "neutral" state, right? The engine RPM's drop to idle when coasting.

Here is my question, when I give it gas again, the RPM's rise and then slightly drop when the gear engages. Is that normal or is that slipping?

I tried it in slower speeds and when I let off the gas and step on it again, the gear seems to engage immediately. Seems to only do that in 4th gear.

P.S., I am beat today so I did not check fluid levels or color but I will be doing that and hopefully get around to changing it.

Thanks for your help.

Normal.

That 'slight drop' is the torque converter clutch engaging.

Like Radi said. Normal operation sound, it's almost a very Jeep kinda sound when it does that.
