No machining required. This valve is designed to allow oil to flow into the converter charge circuit as soon as the engine is started. Tool FA-TL7 is also required. Continuous movement and vibration of the shifter causes wear to the valve body detent ball bore. By oversizing the detent bore and installing this precision steel sleeve and ball replacement corrects the problem.
Sonnax TL12 tool is required. Use with K More Information. Corrects over sensitive kickdown and late upshift. The Sonnax oversized lockup boost valve restores the proper pressures to the switch valve and main regulator valve, ensuring proper flow through the converter and lube circuit and correcting line pressure.converter lockup fail !
Tool kit for K. This upgraded sleeve and plug kit restores hydraulic integrity of the circuit. Excessive wear at the regulator valve pressure sleeve causes low boost pressure in reverse resulting in reverse gear slippage, poor cool charge at idle and poor forward engagement.

The 47RE transmission in these trucks is not a favored transmission among Cummins owners. Some of the most common problems with this transmission involve being stuck in a gear, failure of the torque converter to lock, or hard shifts. These problems are known to make successful mods to this transmission nearly impossible. The 47RE also uses an older design on its components that existed before the transmission was introduced.
The 47RE uses bands to shift gears as opposed to clutch packs. To get a stronger idea of the common problems in this transmission, we talked with Brent Willsey, owner of PowerTech Diesel, located in our home base of Idaho FallsIdaho.

Must be initially installed at an auto repair shop for labor warranty to be valid. Auto repair shop is defined as repair shop whose primary business is automotive repair and provides auto repair service to the general public, and the initial install is done on a repair order. The A, later renamed 47RE electronically controlled governor pressure is a heavier-duty version of A also known as the 46RE which also has electronically controlled governor pressure, versus the earlier RH version, which was hydraulically controlled.
It was used in trucks and vans starting in the mids. While currently used with some internal changes such as the move from aluminum to steel planetary carriers and an increase in the number of clutch plates when coupled to the 5.
The 48RE is an electronically governed, ECU controlled, four-speed heavy-duty overdrive automatic transmission, that is stronger than its predecessor, the series. The base design from the original Torqueflite remains largely unchanged and the addition of a 2-speed output shaft overdrive unit that is bolted to the back of the 3-speed transmission has only two ratios: direct and overdrive.

What it will do. This system can keep the torque converter locked in 3 ed or 4 th gear. With a modification to the valve body 2 ed gear can be locked up. When driving normal freeway speed the torque converter can be locked up with the momentary switch and stays locked up.
The transmission stays in direct drive even when the accelerator pedal is released, there is no freewheeling, RPM level is maintained and torque converter unlock is done with either pushing the momentary switch again or pressing the brake pedal.
When going up long grades select 3 ed gear, overdrive locked out, then lockup the torque converter with the momentary switch. I have found that by doing this I see very little rise in the transmission temperature with a decrease in exhaust temperature of o F. Unlocking the torque converter is done again by pressing the momentary switch or brake pedal.
When go down a long or steep down grade the locked up torque converter will help in slowing but without the added benefit of an exhaust brake. How it works. The system uses three switches, two relays and a light. The first is the momentary switch. This switch is used to signal the transistor in the switching relay to either power the coil and close the contacts allowing power to flow between pins 15 and 87 or stop the power to the coil and open the contacts.
The brake light switch is three switches in one: brake lights, cruise control and anti-lock brake system. When the transistor loses its ground it turns off the power to the coil and the contacts between pins 15 and 87 open stopping current flow to the grounding relay. This switch is used to energize the grounding relay and light. This keeps the torque converter locked when using the brakes.
I use a floor mounted head light dimmer switch to turn it on and off. The switching relay is used to control the power to the grounding relay coil with the use of the momentary and brake light switch. This relay is used in Volvo models and that had 5 speed manual transmissions with the overdrive 5 th gear is a Laycock overdrive unit and provided power to the hydraulic solenoid.
Since this relay is used as only a grounding switch its power rating can be minimal.User Name Remember Me? Join Date: May Location: Moreno Valley, California. Posts: First what are the advantages of the 48 over the 47? Can my 47 be rebuilt to 48 specs or do I need to change complete trannies? What upgrades to a 48 are needed ie TC, VB etc.
I'm looking for everyday power and reliability with good fuel economy for day to day driving and towing my 24' 5ver. I think I'll see an improvement in fuel economy if I can stop the trans from slipping so much around town under light accel. I think it is acting normally but all get reving and slushing is making me crazy!
Sorry about so many questions, enquiring minds and all that. Trac Lock LSD, 3. Sponsored links. Join Date: Oct Posts: 3, Re: 47RE vs. The best and and easist way to upgrade yours to a 48RE is finding a good 48RE core.
Convertor, pump, drums planets, sunshell and all fits right into your case. Use them as a complete set, do not mix the parts. The entire OD rear section, housing and all, will bolt right up to your 47RE case.
Common Problems: Cummins 47RE
You need to use your case for the neutral switch and your VB for the correct GOV sensor and harness for your truck. No mods to the electrics are needed.
The main differences are: 47RE, 5 pinion front planet, may be steel or aluminum that year. The VB is different only because of the neutral switch. The internal harness is different only because of the GOV pressure switch design. If yours was a and up, it is possible to just bolt in the 48RE and only rewire the nuetral switch.
I experiment on my own vehicles but do not endorse the modifications that I make to my vehicles to be used on others. If you use this info that I talk about, you use it at your own risk and responsibility. Two travel trailers, 1 cargo trailer. Lots of ham radios. On Find all posts by TimHolt.
