rayin Report post Posted February 6, 2020 Welcome to the forums! A 25% grade is 25% of a 45° angle = 11.25°. Where is this? The answer is no it is not too much grade for the engine and drivetrain to pull, assuming the entire drivetrain is in good shape. The key is to make sure the automatic transmission does not over-heat since the torque converter is not locked at low speed. Share this post Link to post Share on other sites
