62TE diagnostic on a Chrysler Dodge 200. P0700 P0944 P0740 P0732 P0868

Home - About AutoCodes. Posted and Edit by AutoCodes.Cars by name Trucks and Jeeps. The 62TE six-speed automatic was launched inwith the 3. It was later used on minivans, the with both enginesand the Ram ProMaster. The first gear ratio was much lower, to increase standing-start acceleration; and the differential was beefed up to handle more power.

Smaller steps between ratios helped smooth shifting, as the engine speed doesn't change as greatly with each shift, while the wider range allowed both quicker acceleration and better mileage at highway speeds. The fifth gear was a ratio; the overdrive gear was similar to the 41TE. The 62TE used variable line pressure VLPadjusting its fluid pressure to reduce parasitic losses from the pump and hydraulic system, increasing gas mileage and lengthening the transmission lifespan.

The 62TE six-speed automatic has adaptive electronic control; the torque converter clutch is electronically modulated. A company called Tesma reportedly designed the underdrive packs pictured above ; they have since been purchased by long-time Chrysler supplier Magna.

The underdrive pack includes two clutch packs, one planetary set, two aluminum die-cast housings, input and output shafts, a one-way over-running clutch, six roller bearings, and a total of 60 components altogether. Pistons and dams are stamped.

Walt McCrystal wrote that the 62TE does not come with a dipstick, but one can still check the fluid level by taking the cap off the dipstick tube; the cap can be re-used but will show signs of tampering if it is taken off you can buy replacement caps.

If fluid is low, there is probably a leak. Extreme shuddering, stalling at a stop, and other symptoms can come from using the wrong fluid, or the wrong amount of fluid, so it is important to check this before making repairs or trying fixes.

Arounda firmware update corrected harsh shifting. As with any modern Chrysler transmission, mechanical failures are often detected by the computer and stored as fault codes. Foam or bubbles on the dipstick may mean that the ATF automatic transmission fluid is being mixed with air.

This could be from a low fluid level and air being sucked into the filter along with the fluid. On the more serious side, a severe internal seal leak could be spraying ATF, which then appears foamy as it mixes with air, or a plugging filter is sucking air in along the way to the suction-side of the pump. Late shifting may not be a transaxle problem; the shift points are computer controlled and if the engine seems short of power, upshifts will be delayed.

If it is due for a fluid and filter change, then this will be an opportunity to check the bottom of the pan and chip magnet for debris and such. Make sure that the valve body retainer bolts are properly torqued, as I have found these loose before. Make sure that the old filter o-ring is removed from the filter port before installing the new filter and o-ring.

These old o-rings have a tendency to stay in the valve body and may not be noticed.

Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. P is the OBD-II generic code for a fault involving the pressure of the fluid inside of the transmission.

62te p0868

This could mean that there is too much pressure inside of the transmission or that there is not enough pressure inside of the transmission. Often, a lack of transmission fluid pressure is caused by a lack of transmission fluid.

If fluid has leaked out or otherwise escaped due to a mechanical failure, then there will not be adequate fluid levels inside of the transmission for proper operation. Around this same time, the smell of overheated transmission may become noticeable.

The smell is similar to that of burning oil. Accompanying this may also be smoke from the transmission area, though this only occurs if there is actively leaking fluid in the area.

An improper fluid level may also cause rough shifting and transmission slippage. Automatic transmissions may have trouble shifting at the proper times. A mechanic will diagnose the P code with an advanced OBD-II code scanner that can retrieve the factory readings from the vehicle. The certified technician will view the trouble codes in real time and see exactly when the P code was stored.

Then the code will be reset and the vehicle will be taken for a test drive. If the code appears again during the test drive, then the transmission fluid pressure is the likely culprit.

Wiring will be tested using a multimeter and the factory test points of the circuits surrounding the transmission. The technician will also check for loose, damaged, or corroded wiring around the transmission sensor circuitry. They will also check the transmission for visible fluid leaks.

There are a number of mistakes that commonly arise when the P code appears. Sometimes the technician will under-react and simply fill or replace the fluid in instances when the transmission needs to be rebuilt to function properly.

Other times, the transmission itself is totally fine and the fluid itself is low or too old to be useful. An overheating transmission is a serious problem, and because of this, servicing an overheating transmission often involves taking the transmission out completely. This is not always necessary.This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Transmission fluid serves to lubricate the transmission, and for vehicles with automatic transmissions, to cool the transmission system as well.

When the powertrain control module PCM detects that the pressure of the transmission fluid is either too high or too low, the P trouble code will be triggered.

When the P trouble code is detected, the check engine soon Warning Light will usually illuminate. The vehicle may also emit a strong burning smell from the overheating transmission, and may begin to smoke as well. The transmission may also fail, or may constantly slip. A trained mechanic will use the scanner to assess the freeze frame data.

This allows the technician to gather information about the P code, and search for other trouble codes that may be present as well. If no drivability issues have been detected by the mechanic beforehand, the codes should be reset and the vehicle restarted, to see if the P trouble code returns. If the code does not return, it was likely triggered incorrectly. If the P trouble code remains, the mechanic should first inspect the transmission fluid levels.

If the fluid is low, it should be assumed that there is a leak in the system, and the mechanic should begin searching for where the leak is coming from. Depending on the location of the leak, it may be able to be repaired, and the issue resolved. However, many areas of leakage suggest further damage to the transmission, which will need to be removed and possibly rebuilt or replaced. If the transmission fluid level is normal, the mechanic should check to see if the transmission temperature sensors are faulty.

Only after checking the sensors should the technician search for more severe issues, such as transmission failure or a malfunctioning PCM. After the problem has been identified and repaired or replaced, the codes should once again be reset, and the vehicle restarted, to make sure that the issue is fully resolved. The most common mistake that is made during P code diagnosis is the failure to follow the basic OBD-II trouble code diagnosis protocol in the right order.

Not adhering to the protocol can cause anything from extra time and trouble, to misdiagnosis. One common issue comes when mechanics fix a leak in the system, without assessing whether or not the transmission has been damaged.

Failure to properly inspect the transmission during P code diagnosis can cause severe issues in the transmission.Got a p code in my van and it is in limp mode. It will not shift or go above forty. It says line pressure with an open loop. Just wanted some ideas on what might be the problem. Do you. Good morning. Description below. The line pressure is too high.

Diagnostics below as well. You will need an advanced scan tool to monitor the system for the tests. No common issue.

Every one is different and needs to be checked. It is possible the pressure switch or sensor is the issue. The valve body in the transmission needs to be removed to access these items. Will you be attempting this repair yourself? Diagrams below Theory of Operation This DTC is an informational DTC to inform the technician that transmission has been operating in an open-loop line pressure control for kilometers miles or upshifts resulting from a Line Pressure DTC.

The 62TE Transmission is not designed to operate in open-loop line pressure control for an extended period time. This DTC is intended to protect the transmission. If the DTC sets, the transmission controller will place the transmission into limp-in mode. View repair Repair - Perform the appropriate diagnostics. Remove the clamp plate bolts and clamp plate.

Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. The auto repair labor rates vary widely across the country, and even within the same city. If the actual line pressure is consistently lower than the target while driving, the line pressure low DTC P will set.

The Transmission Control System calculates the desired line pressure based on inputs from both the engine and transmission. The Transmission Control System calculates torque input to the transmission and uses it as the primary input to the desired line pressure calculation. This is called Torque Based Line Pressure.

Related Information. Repair Importance Level: 3. Why is the Engine Light ON?We recommend Torque Pro. Diagnosing this code accurately beyond the basic steps outlined here almost always requires advanced diagnostic equipment such as transmission simulators and sometimes oscilloscopesabove average diagnostic skills in general, and expert-level knowledge of automatic transmissions and their control systems, in particular.

Non-professional mechanics are strongly urged NOT to continue the diagnostic steps beyond what is presented here; doing so could cause irreparable damage to the transmission as well as the entire electrical system of the application. However, this pressure is not constant across all gears; the desired pressure for a particular gear is calculated by the Transmission Control System, using measured engine torque as the primary input data, which is supported by input data from various engine and transmission sensors.

Pressure variation and regulation is accomplished by varying the duty cycle of the Pressure Control Solenoid.

In practice, the transmission line pressure is set to a predefined range. In a fully functional transmission, the actual pressure is both continuously monitored by a dedicated line pressure sensor, and compared to the desired pressure. NOTE: Take note that if the transmission had become noisy at about the same time code P appeared the transmission had already suffered severe mechanical damage, and trying to resolve this code at this point is a waste of time and money.

If the transmission is noisy the only viable option is to replace the transmission. Record all fault codes present, as well as all available freeze frame data. This information can be of use should an intermittent fault be diagnosed later on. Refer to the manual to locate the pressure control harness, but be sure to determine the color coding and function of each wire in the harness to avoid testing the wrong circuit.

Perform a thorough visual inspection of all associated wiring and connectors, and look for damaged, burnt, shorted, disconnected, or corroded wiring and connectors. Make repairs as required if damage is found. Compare all obtained readings with the values stated in the manual, and repair or replace wiring as required to ensure that all electrical values fall within the ranges specified by the manufacturer.

NOTE 1: Pay particular attention to the internal resistance of both the pressure control solenoid, and the line pressure sensor since resistance is a reasonably good indicator of their overall condition. Take note that if the fault persists beyond Step 3, the better option is to refer the vehicle to the dealer or other competent repair facility for professional diagnosis and repair.
