The Automatic transmission in the 2.8 Colorado can be adjusted and tuned accordingly through the vehicles factory ECU to change shift pressures, shifting patterns and even convertor lock up to desired outcome.
The clutch fitted from factory on the 2.8 can handle quite a bit of torque for a factory clutch however the dual mass flywheel is known to be a weak point, for any upgrades over 200hp we recommend replacing clutch and converting to a single mass flywheel and heavy duty clutch.
