I have a 97 ram 1500 with the same thing 45-50 OD kicks in and it would start bucking unless you turned off the overdrive and for me the problem was powerloss due to the injecters, i pulled them off and 2 were 100% clogged. if you clean your injecters be sure to sprey from the bottom to blow out the dirt/rust out of the top to be sure you are not just jamming everything further into the injecters, every easy fix took me a lil over a hour 4 bolts hold the injecter rail in and each injecter has a clip that holds them in after you remove the click carefuly turn the injecter side to side while pulling on them to remove from the fuel rail,then use a pick to pull out the large amout of dirt/rust out of the top of the injecters then you will need to use something to get power to the injecter to open it up, i took 2 pieces of wire with flat ends on then pluged the wires into the injecter the hooked the other side of the wire to the battery, if you do not hear a click sound when u hook to the battery then the injecter is bad, after you hear the click use a cleanning spay and spray from the bottom of the injecter so that the spray comes out the top, after all injecters are clean put them back on the motor, just to be sure all the rubber bushing are on the injecters there are 2 on each injecter 1top 1 bottom, i used a light amount of lube on the rubber seals to put them back in.took it for a test drive and had twice the power and the bucking had stopped.

I hope this helps

How do I keep my transmission from downshifting itself out of overdrive, and turning the O/D On dash light off?


they are supposed to downshift if the load gets too great , like climbing a hill and they do not have to be big hills . a lot depends on the load being carried .5 large adults works a vehicle harder than 1 adult and 5 children

Sounds like you're not getting a downshift and/or the Torque converter isn't disengaging from lock-up position.
IF it's a valve body problem,adding 2 cans of SEA-FOAM transmission treatment and following directions might free it up so it downshifts.It's worth a try.
Now a `little-known' problem with rear DRUM brakes can occur going uphill especially if a wheel bearing gets enough up-down play to let the brake shoes drag.It really CAN happen! don-ohio

There are two D on my cars gear list i dont know which one is overdrive & what is the difference between drive & overdrive.the car is 2004 mercury sble


The D nearest to N is the overdrive. In every day driving just leave it in overdrive. When climbing or decending steep hills you can downshift into Drive, this will prevent the transmission from constantly shifting between gears.

first things first. have you identified whether or not it is using a kick down cable? if it is, chances are this is your issue. if the colar breaks or the cable gets freyed and sticks inside the sheath, it will cause definate shift issues. let me know

96 s10 4cyl automatic shifts great through 1-3 but seems to bottom out and even downshift instead of going into overdrive, drives fine when in drive only.


I believe you have a 4l60e transmission.Do you have a chck engine light? The unit may have a 3-2 downshift solenoid going bad or a possible band ''servo'' leaking. The band applies in 2nd and 4th.You may also have a shift solenoid starting to malfnction......Best

2009 Toyota Camry problems


All Toyota auto trans cars downshift when descending a hill when you tap the brake. This is called "Downhill Shift Logic"; what this is for is to eliminate the double shift when you come to the bottom of a hill and then accelerate. Normal condition. Usually happens above 38 MPH.
Also: The cruise will accelerate when going uphill. Normal condition.Plus: The cruise will not disengage back to the set MPH after you top the hill. Toyota recommends to disengage the cruise when encountering steep terrain.
