Have you looked at Summit Racing?
What year is the car?
Why a poll that only says HELP?

Replace that 5-neutral 4L60e with a 5-speed TKX manual.

The engine sounds alright. The Automatic transmission not so much.
I agree, while it's apart, put in a manual, you'll be glad you did.
You can always sell that automatic to someone with a station wagon.
