Warranty and Other Information Precision Industries

9 1/2-inch torque converters are backed by a 2-year warranty. Included in our 2-year warranty is one free stall adjustment within the first two years from date of purchase. Precision Industries offers the free stall adjustment as a bonus to the customer realizing that most enthusiast usually continue to modify their vehicle as time and money allows. Due to the unique design and versatility of the 9 1/2-inch torque converter the need to purchase an additional torque converter in the future is practically eliminated. The average gain on the 9 1/2-inch torque converter series is 2 tenths on 60 foot and up top 3/4 of a second on overall elapsed times in the 1/4 mile. The average horsepower gain is up to 40-50 horsepower to the rear wheels due to the torque multiplication and increased stall speed. Precision Industries torque converters are purple in color when shipped and depending on the transmission operating temperature may change color and/or the tint of the purple may change. The color changes are used to help us evaluate and eliminate any potential overheating problems the customer may be experiencing. The use of external transmission coolers are left to the customers preference but are not a requirement for using our torque converters. Note that when customers are installing non-lock up torque converters with higher stall speeds a transmission cooler would be beneficial for keeping the transmission at a cooler operating temperature.
