I think my transmission is slipping

I've got a fox with a 450 to 500ish hp 545 with a c6 running 6.90 in the 1/8
The c6 is bone stock whith man valve body 10" converter with 16 passes on it
I know it's not gonna hold up long
The last 2 passes I was shifting at 5200 when I shifted to 2nd the rpm never dropped and wasn't pulling as hard then short shifted to 3rd and pulled hard again
Should I run it till it dies and start over or pull it now and put good parts in it ??
Keep in mind I don't have the funds to go get a 3000$ glide

How far in the future do you plan on making more power? With the power you make now a stock powerglide gear set would live a good while.

The only plans I really have would b to put a 100 shot on it maybe
How streetable is a power glide?

you may just have a loose converter.

2nd gear band mite need re adj. or replaced???

I think I would stick with what you have. We drive our glide on the street with a relatively loose converter but we have a really big cooler that most people don't.

I might would stick with what you have and like they said above check all the adjustments and if needed just rebuild it or get it rebuilt.

If the converter was loose would I only feel it in 2nd?

What does a tight or loose converter feel like sorry still learning
