The automatic transmissions are a weak point in the G's. I would look at getting a valve body upgrade at a minimum if not built 5 AT internals.

I will do valve body but built internals cost alot ..
How many hp it cab handle without built?

Hp isn't the killer. Torque is. Keep the wtq under 450 and you'll be fine.

I think 450whp/wtq - 500 has been the common failure range.
