Jasper Engines & Transmissions offers several benefits when it comes to remanufacturing the Bosch VP44 injection pump.

This pump was found on 1998 - 2002 Cummins B Series engines, which were used in Dodge Ram pickups, Freightliner medium-duty trucks and numerous industrial applications. The design was prone to failure for many reasons.

JASPER uses steel inserts in the advance cylinder bore in place of the original brass insert, eliminating severe wear issues.

In the early-style pump housing, there was a steel piston, which ran through a brass advance cylinder bore. “The brass bore saw severe wear from the use of ultra-low-sulfur fuel and the different metallurgical factors of the two pieces,” says TJ Abrams, JASPER Diesel Quality Group Leader. “JASPER only uses steel inserts in this advance cylinder bore, to eliminate wear and allow the piston to move freely.”

JASPER verifies the date code on the PSG, and reflashes the electronic controller, eliminating limited key cycle concerns.

Another common issue involved the electronic pressure sensor glowplug controller (PSG) on top of the pump. “Early-model PSG’s had a limited number of key cycles,” noted Abrams. “JASPER verifies the date code on the side of the PSG, to eliminate this concern, and will reflash the PSG to the latest calibrations.”

A thicker, metal-plated diaphragm is installed to help eliminate low fuel pressure problems within the pump.

Perhaps the most common failure on the VP44 is the “216″ code (fuel timing error), and the runnability problems that go with it, due to supply pump issues and low fuel pressure to the injection pump. “The pump diaphragm can crack inside the pump, causing excessive wear on the housing,” says Abrams. “JASPER installs the later-style diaphragm, which is metal-plated and is thicker than the original, to help eliminate these types of failures.” Abrams added, “On each VP44 replacement, JASPER recommends that the fuel supply pump is also replaced in the vehicle to help eliminate that failure.”

As an authorized Bosch Service Dealer, JASPER uses state-of-the-art calibration equipment. The Bosch 815 test stand, used in our fuel room, is constantly updated with the latest software,” says Abrams. These updated components, along with JASPER’s up-to-date electronic calibrations, will help keep a vehicle running at peak performance, and meeting the latest emission standards.

Jasper Engines & Transmissions incorporates a procedure to fill the Ford 5R55N/S/W transmissions with the correct level of fluid.

Though the 5R55N, S and W are all similar in design, they each differ in specific areas based on the needs of the transmission’s intended application. However, a common feature is the lack of a dipstick to check fluid levels. “Some common complaints from customers on these transmissions are generally caused by low fluid levels,” says Craig Leuck, JASPER Transmission Division Manager. “These complaints include gear slippage, ‘neutraling’ when fluid settles to one side of the pan while the vehicle is in a curve - losing forward motion, or general transmission failure.”

The 5R55N/S/W is intended to hold 12 quarts of transmission fluid. Inside the pan is a tube, which determines the level of fluid. As the pan is filled, the fluid level will reach the top of the tube, then drip down the tube and out of the pan. “This is the visual indication that the pan is full,” adds Leuck. “But at this point, the pan only holds approximately eight quarts.”

“The next step for the technician is to drive the vehicle until transmission fluid temperature reaches 180 degrees,” says Leuck. “This opens up the transmission cooling system; lowering the fluid level in the pan. The technician can then add the remaining four quarts to the transmission.”

JASPER attaches a bright orange sticker on the pan of each 5R55N/S/W. This will remind technicians the transmission holds 12 quarts of fluid. Also provided with the transmission is a Technical Bulletin explaining the procedure to properly fill the transmission.

This support plate, mounted over the reverse servo cover of the Ford 4R55E/5R55E, allows the transmission to maintain reverse in 1995-2008 Ranger, Explorer and Aerostar.

Jasper Engines & Transmissions has made an update to the reverse servo of Ford 4R55E/ 5R55E transmissions produced between 1995 and 2008.

This update centers around the installation of a support plate over the reverse servo cover of 4R55E/5R55E transmissions found in the Ford Ranger Pickup, Explorer SUV and the Aerostar minivan. Drivers noticed the loss of reverse in these vehicles. The problem centered around the reverse servo gasket of the transmissions.

The gasket lays underneath the reverse servo cover. “These OE gaskets handle in excess of 250 psi when in use,” says Craig Leuck, JASPER Transmission Division Manager. “We have found that aftermarket gaskets can hold about 425 psi. But, we also know these transmissions will see pressures in excess of that.”

“JASPER’s Reverse Servo support plate allows the servo to handle in excess of 600 psi, well above what the servo will see, to make sure these transmissions can maintain reverse,” added Leuck.

The Jasper Engine & Transmission Exchange Employee Stock Ownership Program (ESOP) has acquired Canam Marketing Corporation. Canam Marketing will be operated by JASPER’s sister company, Jasper Innovative Solutions, as the company strives to increase its presence in the United States Postal Service parts market.

Canam Marketing provides vehicle maintenance parts and supplies for LLV, FFV, Windstar, Uplander and other USPS delivery vehicles. Canam Marketing provides product distribution from its Milwaukee, Wisconsin, office, with sales offices in Milwaukee and Las Vegas, Nevada.

“The acquisition of Canam Marketing will be a great addition to JIS,” says Luke Bawel, JASPER Innovative Solutions General Manager. “Canam’s strength in new product development and dedicated workforce, coupled with JIS’s customer service, ordering system, inventory levels, and Transit company will be a winning combination.”

“We see great quality and value in Canam products,” added Bawel. “With this acquisition we will be able to allow customers the convenience of ordering through one system, the availability of ramped up inventory, and on time delivery! We are very excited with this new growth!”

Canam Marketing will continue to operate and, over time, will be merged into JIS. The Canam name will remain for branding purposes and name recognition in the marketplace.

Jasper Innovative Solutions is a supplier of vehicle parts to USPS Vehicle Maintenance Facilities and other fleets throughout the United States. JIS sales offices are located in Bristol, Pennsylvania with distribution facilities in Leavenworth, Indiana.

It is important that JASPER has a clear definition and policy that reflects the best interest of our customers and our company.  Past failure to address this issue has allowed misunderstandings within our company and among our customers.

Cooler free flow can range from one and one-half quarts to over four quarts in 20 seconds.  It all depends on the transmission.  We have established the average acceptable flow as two quarts in 20 seconds.  However, we also know that this is not true in all situations.  For example, the Dodge 47RE transmission requires up to four quarts in 20 seconds.

Replacing the vehicle’s system with an external cooler isn’t always the answer.  Consider the fact that the original manufacturer’s system uses the engine’s radiator to transfer the heat from the transmission’s fluid to the vehicle’s cooling system.  Under all conditions, this is consistent, since it is thermostatically controlled.  An external cooler depends on its ability to transfer the fluid’s heat to air, which is a less-effective method.  It is not monitored by a thermostat and depends on constant air flow to be effective.  There are two situations where they could cause a transmission failure.  One is where the air flow over the cooler is interrupted (snow plows, low-speed towing, stopped in traffic, etc.)  A second problem arises in extremely cold conditions where the transmission fluid is unable to warm-up.  In fact, under extremely cold conditions, it could contribute to the jelling of the fluid.

Flushing the system is no longer effective.  The newer-style coolers have complex internal grids used to enhance heat transferal.  These systems collect debris and are impossible to fully flush. Some systems have thermostats that open at 190 degrees.  The bypass on these systems causes a misleading appearance that the cooler itself is being flushed.

Comparing cooler flow as it exits the transmission to the flow after it passes through the cooler is not always effective.  Some Chrysler 41TE and 46RE coolers, that have contamination, could pass a flow test at normal operating temperature.  However, under load or hot conditions, the cooler will restrict the fluid flow to dangerous levels.

The point is, there is no single answer that fits all circumstances.  So, the next time you purchase a JASPER transmission go ahead and ask about adding a new Spectra radiator, cooler kit or flusher rental to your order.  Listed below are three blanket statements that are considered JASPER’s position.  They are listed in order of preference:

1. REPLACE WITH A NEW SYSTEM (RADIATOR).  Check flow to assure lines and check valves are OK.

2. REPLACE WITH AN EXTERNAL.  Keep in mind the above information and flow test.

3. FLUSH THE ORIGINAL SYSTEM.  A heated, hydraulic shock system is the best.  Flush in a can is not acceptable. Always flow test at operating temperature.

Have you ever had one of those pesky leaks on a transmission that you just can’t seem to find? Jasper Engines & Transmissions has created a transmission submersion test to check assembled units for leaks before they are dynamometer tested.

“This procedure was initially developed to check JASPER transmissions for the United States Postal Service,” said Craig Leuck, JASPER Transmission Division Manager. “We developed an internal linkage system for their transmissions and needed a way to check these units for leaks.”

 When the remanufactured transmission is assembled, Associates seal off all external ports and seals, then inject five pounds of air through the dipstick hole of the transmission. The unit is then submerged in a large tank of water and the Associate checks for air bubbles escaping from the transmission. Units will not be dynamometer tested until they pass this crucial test.

“We’ve found this to be a great way of improving the quality of our transmissions to the customer,” says Leuck. “If five pounds of air can detect an external leak, we can eliminate the chance of transmission fluid finding the same leak.”

JASPER currently dunk tests rear wheel-drive Ford & Chrysler transmissions, along with front wheel-drive GM, the 4L80E and 700R4 postal transmissions. Added Leuck, “The goal is to have the ability to dunk test all light-duty transmissions.”

Jasper Engines & Transmissions has a remanufacturing program geared toward customers with a restoration project, or looking for something extra when they get their engine or transmission remanufactured.

In addition to its current product line, the JASPER Authentic Custom Drivetrains division specializes in remanufacturing engines and transmissions that are currently no longer offered, or have been turned away in the past because they did not fit into a production remanufacturing system.

“If you look at the popularity of television shows that highlight vehicle restoration, there’s a huge market of people out there restoring the older model vehicle they have setting in their garage,” says Alex Ernst, JASPER Authentic Group Leader. “One type of client that would benefit from our division, for instance, is the individual restoring a ‘69 Corvette that is wanting his or her serial numbers to match, and wants their engine to be hand-built by experienced professionals.”

“With JASPER Authentic Custom Drivetrains, we spend extra time remanufacturing an engine,” Ernst added. “We give the customer that hands-on, hand-built treatment that our target customer base is looking for.”

In addition, JASPER Authentic Custom Drivetrains provides some extras for the enthusiast. “Customers can opt to have their engine dynamometer tested in addition to the live-run test we perform on most applications,” said Ernst. “And we can provide the customer with documentation of the remanufacturing process. With a login name and password, they will be able to go to our web site and check the daily progress of their engine or transmission.”

The JASPER Authentic Custom Drivetrains also provides a binder and CD with pictures & specifications so the customer can archive for their own records or use it to authenticate their unit as they show their vehicle.”
