You need to replace the internal solenoids. Not a hard job. Drop the pan, remove the PWM solenoid, and shift solenoids. PWM is causing this issue. New solenoids will cure it. Kit on eBay is $255. https://www.youtube.com/watch?v=yOABDeJQrAE&vl=en https://www.ebay.com/itm/Ram-45RFE-545RFE-68RFE-Solenoid-Assembly-2004-Up-Dodge-Chrysler-Jeep-Mopar/351629865164?fits=Year%3A2005%7CMake%3ADodge%7CModel%3ARam+1500&epid=1853258599&hash=item51dec5f0cc:g:BI4AAOSwjDZYZrmf&vxp=mtr

SOURCE: 92 dodge ram 150 not shifting

Two things happen on the Dodge's. 1. the rear O2 sensor shorts out and meses things up. 2. the Inner seal on the Direct drum (3rd) shrinks and causes a delayed up shift.

Hi,

Here is some possible reasons why your transmission is having those problems .

* The gear shift linkage is binding
* There is an internal problem in the transmission
* The throttle cable is broken or disconnected
* The vacuum modulator on the transmission is faulty or the vacuum line is damaged
* The electronic transmission control circuit may be faulty

2010 ranger when im in town driving at twenty five or thirty do i need to leave transmission in or out of overdrive when exactly should i use the overdrive button????


it is immaterial when the over drive is to be used
If the constant shifting is annoying you then switch it off
The over drive is just that
an extra high final gear in the transmission to reduce the engine rpms at high speed to save fuel . It can be set for automatic engagement or turned of if pulling heavy trailers or caravans or carrying full loads and so save wear on the transmission

Transmission over drive is causing the transmission to slip. When I take off the overdrive the transmission functions normally but it uses much more gas.


Roger, that doesn't even make a whole lot of sense to me. If the overdrive is causing the transmission to slip, wouldn't it also cause the fuel mileage to go down? Are you sure the transmission is slipping? Or is the transmission simply shifting in and out of overdrive? If it is, is it shifting at the proper speeds? Driving at around 40 - 50 Mph will sometimes make the transmission go in and out of overdrive repeatedly. This can be perfectly normal.

Have you checked your transmission fluid level?

Is your overdrive off light flashing? If the transmission is actually slipping the OD OFF light should be blinking at you to let you know there is a transmission problem. Either that, or the Check Engine light will be coming on. In either of these cases, you need to scan your onboard computer network for possible fault codes.

What is the "overdrive" for?


overdrive is just what it sounds like-the transmission turns slower than the engine, allowing more speed with less fuel. It is only applicable in higher speed, low load situations like open road driving, but most modern cars with overdrive will allow engagement at speeds as low as 35 MPH to save fuel. To a point, overdrive is effective for some city driving, but if you constantly do stop and go driving, in city enviornments at speeds under 40, it is best for the engine (and performance) to 'lock out' overdrive.

The overdrive disengages when road speed drops below the threshold. Normally, when you speed up above the threshold you should be able to simply reengage overdrive. You may have a faulty speed sensor preventing that.

99 silverado will not shift into overdrive


have a 1998 K3500 silverado 4x4 with 454 motor and 4L80E transmission. I can not get over 55 or 60 mph. At that speed the transmission down shifts from 4th (OD) to 3rd. The speedometer also drifts from about 50 to 65. If I try to speed up it will down shift to 3rd. I have replaced the VSS on the trasfer case. Is there another speed sensor somewhere? Or could it be the TPS? The truck drives and shift normal up to this point. where should i look next. thanks

How do i reprogram the computer on my 2002 xl7


Try this relearn procedure hopefully it will help

Vehicles equipped with engine or transmission computers may require a relearn procedure after the vehicle battery is disconnected. Many vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When the vehicle battery is disconnected, this memory is lost. The computer will use default data until new data from each key start is stored. As the computer memorizes vehicle operation for each new key start, driveability is restored. Vehicle computers may memorize vehicles operation patterns for 40 or more key starts. Customers often complain of driveability problems during the relearn stage because the vehicle acts differently then before being serviced. Depending on the type of vehicle and how it is equipped, the following complaints (driveability problems) may exist:

Harsh Or Poor Shift Quality
Rough Or Unstable Idle
Hesitation Or Stumble
Rich Or Lean Running
Poor Fuel Mileage

These symptoms and complaints should disappear after a number of drive cycles have been memorized. To reduce the possibility of complaints, after any service which requires battery power to be disconnected, vehicle should be road tested.

Vehicle Preparation

Ensure all components are connected. Ensure transmission fluid level is correct. Warm engine to normal operating temperature. If vehicle has been repaired, perform KOEO and Continuous Memory Code Self-Test and ensure fault codes are not present.

Computer Relearn Procedures

Idle Relearn Procedure

Place automatic transmission in Park or manual transmission in Neutral position. Ensure the emergency brake has been set and all accessories are turned off. Start engine and bring to normal operating temperature. Allow manual transmission vehicle to idle in Neutral for one minute. Allow automatic transmission to idle in Neutral for one minute and then to idle in Drive for one minute. Once initial relearn is complete, process will be completed during normal driving. Always complete the procedure before returning the vehicle to the customer.

Drive Cycle Test (AOD-E, AXOD & AXOD-E TRANSAXLES)

With transmission gear selector in Overdrive, moderately accelerate vehicle to 50 MPH for a minimum of 15 seconds. Transmission should be in 4th gear. While holding speed steady, lightly apply and release brake for about 5 seconds. Stop and park vehicle for a minimum of 20 seconds with transmission gear selector in Drive. Repeat procedure 5 times. Always complete the procedure before returning the vehicle to the customer.

Drive Cycle Test (E4OD)

With transmission gear selector in Drive, press Overdrive Cancel Switch (LED should light). Moderately accelerate vehicle to 40 MPH for a minimum of 15 seconds (30 seconds above 4000-ft. elevation) Transmission should be in 3rd gear. While holding speed steady, press Overdrive Cancel Switch (LED should go off) and accelerate from 40 MPH to 50 MPH. Transmission should shift from 3rd gear to 4th gear. Hold speed steady for 15 seconds. While holding speed steady, lightly apply and release brakes enough to turn brake lights on. Maintain 50 MPH for about 5 seconds. Stop vehicle for a minimum of 20 seconds with transmission gear selector in Drive. Repeat procedure 5 times. Always complete the procedure before returning the vehicle to the customer.
