Stellar Automotive Group 4T80E Forward Sprag Input 2nd Design fits GM

Stellar Automotive Group 4T80E Forward Input Sprag – 2nd Design – Compatible for Cadillac 1993-Up

Eliminate forward sprag rollover, no 2nd gear, and catastrophic forward clutch failure with this upgraded 2nd design forward input sprag from Stellar Automotive Group.

The factory forward sprag is a common weak point in the 4T80E — it rolls over under torque, destroying the forward clutches and leaving you stranded. This heavy-duty 2nd design sprag features reinforced splines, improved cage, and increased element durability to handle higher loads and prevent failure. Ideal for stock rebuilds, performance upgrades, or high-mileage luxury vehicles.

Perfect fit for popular models including:

• Cadillac DeVille, DTS
• Cadillac Seville
• Cadillac Eldorado

Symptoms of a failing forward input sprag:

• No 2nd gear or delayed/harsh 1-2 shift
• Ratcheting noise under acceleration
• Forward clutch burnout on teardown
• Sudden loss of forward drive

Don’t let a weak sprag ruin your rebuild — install the Stellar Automotive Group 2nd design forward input sprag and drive with confidence.

Note: All parts are distributed, not designed or manufactured, by Stellar Automotive Group.
