The transmission oil pressure switch is unique in that its sole purpose is to collect data about the pressure found inside the transmission case, which impacts the timing and operation of shifting a vehicle to a higher or lower gear if needed. I spoke with Bob and explained my truck was having transmissions problems. Hear from other customers via the 101 reviews on parts for your Dodge Ram 1500. It is fairly common for these. It might also not be seated correctly. Shop online, find the best price on the right product, and have it shipped right to your door.
You can also purchase an aftermarket replacement from your local Auto Parts Store. Replace the filter and O-ring and make sure everything is seated well before re-assembling. This is called Torque Based Line Pressure. When it comes to your Dodge Ram 1500, you want parts and products from only trusted brands. The plunger is in turn attached to one of the shift valves in the valve body. Here at Advance Auto Parts, we work with only top reliable Pressure Sensor product and part brands so you can shop with complete confidence. If this component wears out or breaks, it will trigger a series of warning signs to occur, which may alert the driver that a problem with this part exists and that it needs to be replaced as soon as possible.
Posted by Brian on Feb 13th 2018 Had a shuttle shifting issue and was trying to trouble-shoot on my own. Check the filter tube and O-ring, too. One of these components is the transmission oil pressure switch, which is designed to monitor the amount of pressure built up inside the transmission case as fluid flows through a series of chambers and channels to permit the transmission to smoothly shift gears. The transmission was searching for second gear during light throttle before the changes. The quickest way to test a solenoid is using a hand held ohm meter. It is designed for rear wheel drive vehicles and is usually paired with the smaller V8 engines. Any of these small problems can cause the transmission to suck in air sporadically, at which point it loses oil pressure and feels like it is in neutral.
The transmission operates the solenoid pack to change hydraulic flow through the valve body to various clutches in the transmission. Dave emailed me back and asked me to let him know when he could call me to discuss further. In addition, the line pressure is set to a preset level 827 or 931kPa 120 or 135 psi during shifts and in Park and Neutral to ensure consistent shift quality. In production between 1999 and 2003, it was used in many popular Chrysler vehicles, including the and Liberty, and the Dodge Dakota, Durango and Ram pickup truck. I have never in my life 59 years had such a great customer support experience!! The actual line pressure is continuously being compared to the desired target line pressure. Since I am very inexperienced with transmissions, he spent nearly thirty minutes on the phone with me and answered all of my questions and gave me some additional tips. The solenoid pack is mounted directly to the valve body; its connector protrudes from a hole on the left side of the transmission.
Backing off the throttle and it would re-engage. A properly working solenoid should return a reading of between 20 — 30 ohms. It felt like the transmission was starting in 3rd. Re-manufactured transmissions also include a much better warranty than rebuilt transmissions; usually compared to 90 days for the rebuilt transmission. Odds are that the transmission is in this default gear due to a malfunction of some sorts that must be repaired before you drive again. Turning off the engine for 10 seconds and re-starting would fix the problem temporarily. Although out of production for a while now, there are still plenty of these popular vehicles on the road.
The companies that re-manufactured transmissions believe so strongly in their workmanship and quality of parts that they feel very comfortable offering such a long warranty period. There is a reason for this difference in warranties. I would highly recommend this part since I had replaced the sensor only 6 months earlier. Evidently the plastic sensor replaced the more robust brass version on the previous generation. Some of our top Pressure Sensor product brands are , and.
I waited till I got all the parts at once to service the transmission, and man what a difference it's just like a brand new transmission, I just followed the simple instructions, adjusted the front band, poured in the new fluid to the proper level and test drove it. If you can catch the problem before it ruins the transmission, install an aftermarket transmission cooler to help keep temperatures under control. What is the transmission oil pressure switch? Changed the cam and crank sensors and it ran normally for a test drive and thought I had it fixed. When the wire is not secured, it can cause the sensor to register lower pressure than what is inside the transmission. I found this product and emailed Goerend to verify I was thinking about the issue correctly, along with a long list of other transmission questions.
The Transmission Control System calculates torque input to the transmission and uses it as the primary input to the desired line pressure calculation. I have a 2002 Jeep Liberty, 3. Connect the two leads from the ohm meter to the two leads coming off the solenoid you want to test. These couple changes in the transmission made a world of difference plus the transmission pan is just plain cool! When a 12 volt charge is passed through the coil winding found inside the solenoid, it generates a magnetic field and cause the plunger to move the valve. The plastic version is prone to failure and a weak link in the transmission. Due to the fact that it's located underneath the vehicle, the transmission oil pressure switch is subject to extreme conditions and working in a harsh environment.
The transmission oil pressure switch is attached to the transmission case and was engineered to monitor and relay the oil pressure inside the transmission to the on board computer found in most vehicles. Thanks for your time and comments. I installed the part and the truck runs flawlessly. The oil pressure switch of the transmission is vital for the smooth and efficient operation of the vehicle. .
If you get no reading you have a break in the internal wire coil. The Transmission Control System calculates the desired line pressure based on inputs from both the engine and transmission. Think problem is solenoid pack and wondering what your thoughts are. Skip the repair shop, our top-rated mechanics come to you. Like any other sensor, it can become damaged or simply wear out. The chance is high one will end up in your shop for repairs sooner or later. If you get a low reading you most likely have a short in it.
