Default Trans problem with video

Already changed the fluid and filter. Silly question but, is this considered slipping? 93 Auto, Z07. Also, when I put it in drive and let go of the brake, it doesn't move as much as used to. I'm not on the throttle hard. It would normally shift at 10 then 20. But it's shifting at like 20 now.

What's weird is it doesn't at 10 like used to. My other C4 shifted at that speed as well. This car has driven me crazy Sometimes it won't even shift till 25 mph. And I'm not on the throttle hard.

Looks pretty normal to me but I don't have an auto C4. If it concerns you, you can try adjusting the TV cable.

I re-adjusted it, per the FSM. Found the instructions in a thread. Same thing. I know it's not just me because when above 10mph, it almost feels like I'm revving. But obviously the car still accelerates. It's only noticeable from a dead stop. Other than that, it won't do what I'm describing. I'll try and get another, better video tomorrow.

Well slipping would be RPMs increasing while the mph stays the same... I didn't see that in this video. My 91 camaro with 2.73s shifts at around 30 mph in first gear. I think you're fine.

Thanks Tom. Every gear works, even kicks into overdrive. I just don't get why it's shifting late
