Question about Dodge Dakota

1 Answer

I have a 1997 Dakota 121,000 miles and replace the transmission 15,000 miles ago. I bought this from Ebay. Worked fine till now and it won't shift into low when you stop and doesn't shift to over drive when you run it. If you shift to low manually it will work. I am a deisel mechanic and will be working on this myself but don't have much knowledge of the valve body in my automatic trans. Can you help. My email is

  • Servos/Accumulators The servos are hydraulic pistons and cylinders. They resemble the hydraulic actuators used on many other machines, such as bulldozers. Hydraulic fluid enters the cylinder, under pressure, and forces the piston to move to engage the band or clutches.

    The accumulators are used to cushion the engagement of the servos. The transmission fluid must pass through the accumulator on the way to the servo. The accumulator housing contains a thin piston, which is sprung away from the discharge passage of the accumulator. When fluid passes through the accumulator on the way to the servo, it must move the piston against spring pressure, and this action smoothes out the action of the servo.
    Hydraulic Control System The hydraulic pressure used to operate the servos comes from the main transmission oil pump. This fluid is channeled to the various servos through the shift valves. There is generally a manual shift valve, which is operated by the transmission selector lever, and a shift valve for each up shift the transmission provides.
    Most automatic transmissions are electronically controlled; electrical solenoids are used to control the hydraulic fluid. The shift solenoids are regulated by an electronic control module. Shift timing is regulated through sensor feedback information provided to the electronic controller.
    On older transmissions there are two pressures that control the shift valves. One is the governor pressure which is affected by vehicle speed. The other is the modulator pressure which is affected by intake manifold vacuum or throttle position. Governor pressure rises with an increase in vehicle speed, and modulator pressure rises as the throttle is opened wider. By responding to these two pressures, the shift valves cause the up shift points to be delayed with increased throttle opening to make the best use of the engine's power output.
    Older transmissions also make use of an auxiliary circuit for downshifting. This circuit may be actuated by the throttle linkage, vacuum that actuates the modulator, or by a cable or solenoid. It applies pressure to the downshift surface on the shift valve or valves.
    The transmission modulator also governs the line pressure, used to actuate the servos. In this way, the clutches and bands will be actuated with a force matching the torque output of the engine.

    Why is my 97 dodge dakota reluctant to shift from first gear until it warms up

    When did you last change the trans fluid and filter? Ever? Do so and you may have a cheap fix, plus adding many miles of use to trans. This fluid and filter should be changed every 24K miles or two years for most vehicles. It's surprising how many folks don't do this. You did read your owner's manual didn't you?

    Dodge dakota 2005 automatic transmission, when starting from a stop or low speed sounds as if it is low on fluid rpms high started doing this on tollway when pulling out from the toll both ????seems to...

    Manually shift thru all gears up & down the scale. Try adding Motorcraft Additive Friction Modifier, available from Ford parts dept. This REALLY STINKS!!! Don't get any on you. Pour into trans fluid. Drive a few miles shifting manually thruthe gears, then do a normal start stop drive several times. This will luburcate trans, normally used for differential but has worked in automatic transmissions of all makes for years. Otherwise mechanical problem for transmission repair facility.

    HI, when the transmission heats up the solenoids stick and sets the transmission in fail safe mode common issue with Chrysler transmission. I would recommn\end your local transmission shop.
