This tutorial is a primer that'll help you find out if the problem with your Dodge or Jeep's 42RE, 44RE or 46RE computer controlled transmission is electrical in nature or if the problem is due to internal damage that'll require an overhaul without having to drop it and tear it down.

All 3 of these are computer controlled and have an electrically operated valve body to control the upshifts and downshifts. All three also provide a self-diagnostic feature as part of their transmission control program.

The most important thing to know, when trying to troubleshoot a transmission problem, is that the 42RE, 44RE, or 46RE automatic transmission usually fails in one of two ways:. All Articles: 3.

Do NOT follow this link or you will be banned from the site!There is a common issue with shifting on a number of Jeep Grand Cherokee models as they age and their mileage increases. You're often still able to drive the vehicle, but it only operates in one or two gears. For example, you may find that you're only able to drive the car in the automatic transmission's third gear, only being able to select the other two gears when you shift the transmission manually.

The most common cause of transmission problems is the easiest to fix: check the fluid level in the transmission and restore it to the proper levels. Very often, this will solve the problem. But Jeep Grand Cherokees seem especially prone to more serious transmission problems, and some owners are quite vexed at their inability to determine the causes. On models with OBD onboard diagnostics systems, a code scanner plugged into the diagnostic port gives you a reading to help identify the problem.

However, easy solutions still exist even if you don't have a code reader. Below, you'll find the list of Transmission Fault Codes for Jeep automatic transmissions. You may or may not be skilled enough to actually fix the problems indicated by the flash codes yourself, but you're better-armed with an understanding of where the issues lay as you seek help from a mechanic.

The rear band is applied in 1 and R range only. The overdrive clutch is applied only in fourth gear. However the overdrive direct clutch and overrunning clutch are applied in all ranges except fourth gear. Examples… If slippage occurs in first gear in D and 2 range but not in 1 range, the transmission overrunning clutch is faulty. Similarly, if slippage occurs in any two forward gears, the rear clutch is slipping.

Applying the same method of analysis, one note that the front and rear clutches are applied simultaneously only in D range third and fourth gear.

If the transmission slips in third gear, either the front clutch or the rear clutch is slipping. If the transmission slips in fourth gear but not in third gear, the overdrive clutch is slipping. By selecting another gear which does not use these clutches, the slipping unit can be determined. For another example, if the transmission also slips in Reverse, the front clutch is slipping.

If the transmission does not slip in Reverse, the rear clutch is slipping. If slippage occurs during the shift or only in fourth gear, the overdrive clutch is slipping.

Similarly, if the direct clutch were to fail, the transmission would lose both reverse gear and overrun braking in 2 position manual second gear. If the transmission will not shift to fourth gear, the control switch, overdrive solenoid or related wiring may also be the problem cause.

If the transmission will not shift to fourth gear, the control switch, overdrive solenoid or related wiring may also be the problem cause. This process of elimination can be used to identify a slipping unit and check operation. Although road test analysis will help determine the slipping unit, the actual cause of a malfunction usually cannot be determined until hydraulic and air pressure tests are performed.

Practically any condition can be caused by leaking hydraulic circuits or sticking valves. Unless a malfunction is obvious, such as no drive in D range first gear, do not disassemble the transmission. Perform the hydraulic and air pressure tests to help determine the probable cause. OK So now comes the fun part.

You will need a pair of pressure gauges. I bought a pair of cheap Home Depot psi gauges, and used some grease gun hose and then some nylon tubing to connect the two. As you can see on this chart that it mirrors the Shorthand Diagnostics section. Using this chart we can now know which test port to use for testing. Now for the testing phase. Here we can see the locations of the test ports on your 47re.

Ports are located on the Passenger side, Port 5 is on the drivers side of the transmission above the one transmission cooler line. So in order to perform these tests you MUST jack the rear axle up so the tires are off the ground, Block the front tires, and then unhook the the TV lever from the transmission side. When testing you want to watch that the accumulator moves in a smooth fashion, and that both ports are reporting where they should be.

You will leave one of the pressure gauges on at the Accumulator port through tests What makes it pretty easy to tell if the automatic transmission failure is just a solenoid related issue Remember, what will tell you that you have a solenoid or internal transmission sensor problem is:.
