ROCKWELL INTRODUCES NEW LINE OF 10-SPEED TRANSMISSIONS

 LAURINBURG, N.C., Jan. 29 /PRNewswire/ -- Rockwell International Corporation's Automotive business has expanded its family of transmissions with a new lineup of 10-speed transmissions that offers North American truck operators a well-balanced ratio match with today's gear fast, run slow powertrains.
 Five new A-ratio overdrive 10-speed transmission models will be available in early 1993, featuring a full complement of torque ratings ranging from 1,150 to 1,550 lb-ft. The company also plans to introduce 10-speed direct drive models later this year.
 The new 10-speed overdrive transmissions, which will be available through all major North American truck OEMs, include:
 Torque Rating
 Model (lb-ft) Available
 RMX10-135A 1,350 March 1993
 RMX10-145A 1,450 March 1993
 RMX10-115A 1,150 May 1993
 RMX10-125A 1,250 May 1993
 RMX10-155A 1,550 May 1993
 According to James R. Hardy, general manager of Rockwell's Transmission business, the company's family of 30 transmission models in 9-, 10- or 13-speed configurations offer high reliability, smooth shifting and low noise and vibration levels, plus increased startability and lighter weight than competitive models.
 "We're coordinating efforts with each of the heavy-duty truck engine manufacturers to ensure an optimum match between our transmission designs and today's high torque, low cruise rpm engines," Hardy said.
 Benefits of Rockwell's 10-Speed Transmissions
 According to Frank A. Palmeri, director of sales and marketing, Rockwell's new 10-speed transmission models offer truck operators a number of competitive advantages, including:
 -- A deep 11.2:1 first gear and .7aring.
 -- Well-balanced ratio steps of 34 percent to 37 percent from top to bottom that promote fuel efficient driving techniques, while enabling drivers to maintain engine rpm after upshifts for smooth shift feel.
 -- An installed weight advantage of up to 37 lbs, versus competitive 10-speeds, for increased productivity.
 Palmeri noted that the balanced ratio steps of Rockwell's 10-speed are well-matched to today's popular engine designs. "Engine manufacturers recommend keeping rpm above peak torque after upshifts in the top gears and lugging back to peak torque before downshifting. Our new 10-speed can help drivers stay in the recommended operating range for optimum gradeability performance and excellent fuel economy.
 "More than ever, fleet operators are spec'ing with the needs of their drivers in mind," Palmeri said. "The smooth, easy shift feel of Rockwell's new 10-speed, combined with the superior lug performance of today's engines, provides a powertrain tailored to operators who demand both comfort and driveability."
 Palmeri also noted that spec'ing Rockwell's 10-speed can help address low-speed maneuverability issues resulting from use of faster axle ratios. "As overall drivetrain ratios get faster (lower numeric), vehicle reversing speed increases. Rockwell's 10-speed can help slow reversing speed back down to a safe and comfortable level for the driver," Palmeri said.
 According to Rockwell, gross combination weight (GCW) applications exceeding the typical 80,000 lbs. can also benefit from the deep reduction and close steps in Rockwell's 10-speed models.
 "Drivers of heavy GCW rigs can start out in first gear and comfortably shift through a 35 percent step to second gear without excessive wheel hop or clutch wear. The result is a much smoother and more progressive shifts at the lower vehicle speeds," Palmeri said.
 Two New 9-Speed Models
 The company also announced the immediate availability of two new 9-speed models rated at 1,550 lb-ft. These direct (RMO-155A) and B-ratio overdrive (RMX9-155B) transmissions were specifically designed to handle the torque output of available 1,550 lb-ft engines, a growing segment in today's market.
 Each of Rockwell's 9- and 10-speed transmissions uses a non- splitter, two-speed auxiliary back box that incorporates the latest in gear design and synchronizer technology to provide high reliability and quiet operation. Providing even steps without need for a more complex splitter can also save up to 37 lbs. installed weight when compared to competitive splitter transmission designs.
 Incorporating Popular Features and Benefits
 Joe Allen, chief engineer, said the company's entire line of 9-, 10- and 13-speed transmissions employ a number of features and benefits that customers have come to expect from Rockwell, including:
 -- Fine mesh gearing that's up to 18 percent wider to handle the output of today's high-torque engines.
 -- Larger diameter mainshafts with stronger, long-life splines for increased reliability and durability.
 -- Tapered bearings used throughout, in both main box and auxiliary section, lasting two to four times longer than straight roller bearings.
 -- A patented soft-molded, ergonomically designed shift knob that helps reduce driver fatigue.
 "While the new line of 10-speed transmissions represents the latest member of the Rockwell family, all of our models share a cadre of design enhancements that the market has come to recognize and value over the past three years," Palmeri said.
 Advanced Lube Program Available
 The company's new line of 10-speed transmissions will be included in Rockwell's Advanced Lube Program, introduced last October. Requirements for an initial lube drain at 3,000-5,000 miles has been eliminated. Fleets can now have their transmissions filled at the OEM's factory with an approved synthetic lubricant, and then run up to 250,000 miles without a lube drain.
 According to Palmeri, the Advanced Lube Program for transmissions can eliminate up to 13 of 15 lube changes normally required with petroleum lube during the first 750,000 miles of service, provided an approved synthetic lubricant is used.
 "End-users are free to choose from a list of over 30 synthetic lubricants approved by Rockwell for use in its transmissions," Palmeri said. (Note: An extensive list of approved lubricants is also available for Rockwell drive axles.)
 Maximum benefit from the Advanced Lube Program is derived when fleets specify both a Rockwell transmission and extended drain drive axle. Savings are possible in excess of $85,000 and over 9,400 gallons of lube by a fleet of 100 tractors during 1 million miles of service.
 Transmission Lineup Supported in the Field
 All Rockwell transmissions carry a 5-year/500,000-mile warranty when approved petroleum lubricant is used, or a 5-year/750,000-mile warranty when an approved synthetic lubricant is used exclusively. Both options include coverage for parts and labor and are free of charge to the end- user. (For complete warranty details, see Warranty Certificate No. SP-9260.)
 Truck operators interested in more details on Rockwell's new transmission models for 1993 should call the company's new ROKFAX info- on-demand service. Simply dial 1-800-FON0ROK (366-0765), enter the extension NEW (639) when prompted, and the information will be faxed immediately.
 Rockwell's comprehensive warranty program and ROKFAX service are examples of the valuable services offered via the company's Drivetrain Plus(TM) program, featuring the industry's most complete drivetrain lineup of components and value-added services.
 Other Rockwell components in Drivetrain Plus include axles -- steer, drive and trailer; brakes -- cam, wedge, air disc and automatic slack adjusters; clutches, transmissions, driveshafts and universal joints; transfer cases; on-board, electronic management systems; vehicle control systems; and aftermarket parts.
 The company also supplies heavy-duty truck plastic hood assemblies.
