Are there any problems with the 47RE transmission?

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.

Where can I get a Cummins 47RE transmission?

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 Falls, Idaho. We also interviewed William Terry of Cedar City, Utah-based performance transmission shop Power Driven Diesel.

What are the most common problems with a Cummins transmission?

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. That is largely due to the small size of the transmission’s shafts, clutches,…

When did the first automatic transmission come out?

Sometimes, engineering incompetence is the culprit. Sometimes it’s penny-pinching. The modern automatic transmission got its start in 1934, when REO—a Lansing, Michigan, automobile and truck manufacturer—developed the Self-Shifter. A clutch pedal was required for shifting into forward or reverse, but not for shifting between forward gears.

When did the TorqueFlite 47RE transmission come out?

The TorqueFlite 47RE transmission was the dominant choice in Dodge Rams from the mid 90’s to early 2000’s. We are pleased to say that the 47re transmission is for sale now at our lowest price ever.

What should I replace in my Cummins 47RE transmission?

The first part to replace is the 47re governor solenoid. stock governor solenoid failure symptoms would be a 1-2 shuttle shift. the best thing you can do is a 2nd gen cummins GM governor solenoid upgrade. The gm style governor solenoid is much bigger and can handle higher 47re transmission line pressure.

What kind of transmission does a Dodge Rams use?

The TorqueFlite 47RE transmission was the dominant choice in Dodge Rams from the mid 90’s to early 2000’s.

What makes a Cummins 47RE different from other transmissions?

The 47RE also uses an older design on its components that existed before the transmission was introduced. That’s not like Ford and GM transmissions, which had entirely new designs implemented. The 47RE uses bands to shift gears as opposed to clutch packs.

What causes no reverse on a 4R44E transmission?

Loss of certain gears can occur due to issues in at least two other circuits. Loss of solenoid oil due to end plug leakage can cause no Reverse, and loss or 3rd or 4th and can be repaired with 37947-13K.

What causes the Revs to drop in a car?

ShareTweetEmailWhatsapp Dip the clutch in any normal car and the revs will drop due to the inertia of the flywheel and the lack of air entering the intake as the throttle is released. Once a gear change has been completed and the clutch pedal is released, the engine speed will rise back up to meet the speed of the transmission.

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.

Why does my GMC TRA not go into gear?

If there is an issue with either of these the vehicle may experience problems shifting or transferring power to the wheels. If these are not the problem then it could be possible that the transmission is having internal faults, perhaps a worn torque converter, or transmission gears, inside of the transmission.

What should I do if my gearshift is not working?

3. Gearshift Linkage Mis-adjusted. 3. Adjust linkage and repair linkage if worn or damaged. 4. Torque Converter Drain Back (Oil drains from torque converter into transmission sump). 4. If vehicle moves normally after 5 seconds after shifting into gear, no repair is necessary.

What should the reverse line pressure be on a 47RE?

Reverse will be over 250psi usually. – WOT Is defined as the TV lever being moved fully rearward into the open position. You should see a smooth increase of line pressure to the maximum. This test checks pump output, pressure regulation, and condition of the rear clutch and servo circuit.

What should the rear servo port pressure be?

Rear servo port should have the same pressure within 3psi. This test checks pump output, line pressure and pressure regulation. This test is performed in D2 at 1000 rpm. Line pressure should be 54-60psi at idle and gradually increase to 90-96psi at WOT. Test Three: This test checks pressure regulation and condition of the clutch circuits.

Which is better a remanufactured transmission or a rebuilt transmission?

Remanufactured transmissions carry a longer, 3 year, nationwide warranty with additional upgrades while a rebuilt unit generally carries up to a 1 or 2 year warranty and upgrades vary from shop to shop. Reman 47RE vs. Used 47RE? Buying a used 47RE transmission may save you money.

Why is the 47RE transmission important to ATS?

That’s why ATS modifies the transmission to make it the strongest and most reliable part of your drivetrain. With the many shortcomings of the 47RE, none are more important than the clutch packs. This is what takes the power load and transmits it to the rear wheels.
