But have decided against it. However, the TCM needs to know input shaft speed.

This occurs in 2nd, 3rd and 4th gears and when it does, both the N2 and N3 rpm sensor readings are exactly the same if the transmission is functioning correctly. This not only damages the conductor plate, it also causes a no start condition. This is due to the carrier being driven by the input shaft through the internal ring gear, which will slightly reduce the speed of the carrier.

In some cases, it has actually worked out for them. Since the N3 is inoperative in reverse standard mode, 1st 72.26 5th gears, it appears that the N3 sensor is redundant and provides no additional information.

For DodgeChrysler and Jeep vehicles, gear ratio errors can be the result of a slipping transmission, an incorrect ratio planetary, an incorrect ratio differential, the wrong TCM is being used or, the wrong pinion factor was programmed into the TCM.

This conductor plate brings up a few very interesting points to mention, which is really the primary focus of this article. The N2 is the next sensor back on the conductor plate silver top and reads the rotation of the front planetary carrier assembly. If the on coming clutch applies too quickly, the overlap of the two clutches causes a very brief tie up or bind up, which feels like an abrupt or harsh shift.

This gives the transmission the capability to be fitted behind engines as small as a 4 cylinder to as strong as a 12 cylinders. But the atsb of times it usually comes back with various codes. This drum has the front planetary sun gear attached to it and it lugs into the B1 clutch on the pump.


By way of capillary action, fluid is drawn up through the wiring filling the TCM Figures 4 and 5. Several different gear ratios are available with this transmission as well as various amounts of clutch plates within a clutch pack assembly. As one clutch comes off, it needs to be carefully timed with the on coming clutch. Too many wives might find oily residue on their dishes after removing them from their dishwasher.

With some Mercedes-Benz vehicles, there have been reports of transmission fluid being accidently poured into the engine oil fill hole after repairs.

What this means to you and me is this. But when the K1 clutch applies, it locks the sun gear to the carrier forcing the entire front planetary assembly to rotate at actual input shaft speed. The ISS Factor Making sure the clutch is used properly is almost as important as these other tips for keeping this transmission in gear. This occurs in Reverse or a forward gear positions only.

Although the adapter plug is supposed to prevent transmission fluid from leaking fluid into the harness connector, it could fail.

This statement Chrysler provides in accompaniment with this chart reveals some computer math strategy. Figure 11 is a first gear screen capture at 10mph of a Jeep Grand Cherokee which provides the following data:.

The computer is programmed to divide the 0. This value is then used to monitor gear ratio health of the transmission by the computer.

Mercedes 722.6 / NAG 1

This is a clutch-to-clutch shifting transmission, meaning there are no bands in the shifting process. The part number to replace it is, A 11 Another misunderstood scan tool parameter that occurs is with the Transmission Fluid Temperature located in the electrical conductor plate as shown in Figure The internal conductor plate just previously mentioned is another commonly known issue with this transmission.


This occurs in Park, Reverse Standard Mode, 1st and 5th gear. But it will definitely ensure that the new TCM you put in will not get loaded with fluid again. Jenric Auto Sales Car Dealership.

The chart in Figure 10 confirms the normal operation of the speed sensors, the N3 sensor being at 0 in reverse S1st and 5th gears while the N2 is providing an rpm reading.

I am almost tempted to share with you one of the craziest methods I have ever heard being used by some individuals to clean these TCMs. Unaware, the vehicle is started with a dry transmission sump. The remedy is a new sleeve atg the internal conductor plate and external harness connector called the Adapter Plug; part number A 02 53 Figure 6. It is mounted on the valve body, which the solenoids bolt down onto Figure 7. First one to mention is the TCM gets filled with 72.6 fluid due to a leak into ats solenoid harness connector Figure 3.

The N2 rpm of is divided by the 0. What this means is that whenever the B1 clutch is applied it holds this drum stationary.

Integral to this conductor plate is the starter interlock contact, transmission oil temperature sensor, the N2 and N3 speed sensors.

Too fast of a release with the off-coming clutch and the shift will transition will consist of a slight engine flare making it feel like a slip.

The mechanical make up of this transmission consists of three planetary gear sets:
