How do I know if my Lexus drivetrain is damaged?

Can my LS400 malfunction warning light be reset at home?

Resetting a malfunction warning light at home may be possible sometimes, but it is never recommended.

Resetting the check engine light without addressing the underlying issue may temporarily remove the warning, but it will not fix the root cause of the problem.

Is my LS400’s transmission part of the drivetrain?

The transmission is a crucial part of your drivetrain system. The drivetrain in your LS400 is responsible for transferring power from the engine to the wheels to move the vehicle forward. This system consists of several components, including the transmission, driveshaft, differential, and axles.

What Does the Drivetrain Do In Your 1991 Lexus LS400

The drivetrain is responsible for transferring power from your LS400's engine to its wheels. It spans the full length of your Lexus, from back to front. It’s a very intricate system of moving parts and is comprised of everything after the engine transmission: driveshafts, axles, joints, differentials, and wheels. Care for your 1991 Lexus LS400 to maintain its performance power. Follow Lexus's recommendations for lubricating bearings/gears and checking/changing differential fluids to minimize repairs over time.
