I had an automatic Hyundai Excel (was a cheap car when I needed a cheap
car) that had tranny problems. It shifted early, the shifts were soft, and
I was sure the clutches were gone.

Then I replaced the thermostat to solve an active temp gauge.

The tranny problems went right away.

Does this apply to your situation?

My thermostat was stuck open.
