Do I have a vacuum leak?

[SR97GT66]

Now that I've got my '66 running, when I hit the gas the car barely goes. I was flooring it and going like 15 mph. Basically it seemed like it wasn't shifting into second gear. What could be causing this? A vacuum leak maybe? It's a 289 w/ a c4. This was never a problem before I let it sit for 8 months. I added some tranny sealer to see if that would help but no luck. Thanks.

Check the trans fluid level, sounds like it's low.

I did that already. It was low after we got it started but I filled it up.

Did you run it thru the gear pattern then recheck the fluid level?
they will sometimes need more fluid after it has pumped thru the system.

No I didn't recheck the level I'll do that once these 20+ inches of snow melts. Thanks.
