The info I've gathered points to overdrive sprag. In replacing this part, do I need to purchase the planetary? Thanks

Good morning,

I would do some diagnostics first before assuming anything.

I would check and see if you have any mainline pressure. Without pressure, nothing will work. You could have a front pump failure or torque converter failure and must be ruled out before pulling the unit and inspecting.

I attached a flow chart for you to follow for the failure.

Let me know if you have any other questions.
