Drive Plate (Flexplate) for Automatic Gearbox ⚙️

This heavy‑duty steel disc sits between engine and automatic transmission, bolting to the crankshaft and fastening to the torque converter. It transfers engine torque to the gearbox, carries the starter ring gear, and is factory-balanced to keep vibration low. In short, no plate, no drive. 🚗

Why this part is needed 🧰

It links the engine to the converter, allows slight elastic “flex” as temperatures and loads change, and gives the starter a reliable gear to crank the engine. It also helps damp torsional pulses to protect bearings and pump gears inside the transmission.

How it works 🔧

When the engine turns, the plate spins the torque converter input. The starter pinion engages the ring gear on the perimeter to start the engine. Slots and profiles in the disc let it flex microscopically, keeping alignment while preventing stress cracks.

What happens if it breaks ❗

Common signs: metallic rattle at idle in gear, chirp or grind during start, harsh vibration, delayed or no drive, or a starter that spins but the engine doesn’t crank (sheared center or teeth). Cracks around bolt pads can grow and lead to sudden loss of drive. Metal noise after shifts or new leaks at the rear main can also point to a warped plate.

Tech tips for replacement ✅

Inspect converter pilot, replace converter nuts, torque bolts in a star pattern with threadlocker as specified, check runout, verify 1–3 mm converter free play, and recheck starter mesh. Always address rear main seal while accessible. 🛠️
