2000 buick lesabre won't shift into overdrive

When od is selected and trans should be shifting into od there is a whining sound coming from the trans and it stays in third gear. when the throttle is released,as to force a shift, the driveline disengages as if shifting into neutral. it immediately re-engages with throttle pressure. if gear selector is kept in third position everything operates normally, minus overdrive. lock-up converter also appears to be functioning properly. changed fluid and filter, no abnormal debris,metallic material,burnt fluid or other strange indications found in trans pan.

    Check the transmission module.

    You might want to see if you got a 4 prong electrical plug on the trans. if it does unplug turn ignition to on and with a test light test each one, one should be hot, thats what makes it shift to overdrive, Now if it dosent have one, it could be the govenor sticking, witch is on side of trans.has a round cup like cover, its under that cover. Are you sure its got a lock up converter, i thought they did away with them in the mid 80's.

SOURCE: my 2001 buick regal ls, will no longer shift into

I believe that the solenoid that controls the overdrive is accessable from the transmission pan area. The solenoids that control the shifting are located in the side. The 4t65e transaxle has been known to have problems with overdrive for more than one reason though, so start with that solenoid. If that doesn't work, you may have luck with a shift kit. My car used to shift rapidly in and out of overdrive, after I installed a shift kit, I have had no further issues. I used the '4t65e sk' kit from TransGO.

SOURCE: Power Steering pump appears to be leaking but is full????

Just guessing. Could it be a warped brake disk? That would cause vibration. And vibration in steering might conceivably cause splashing out the power steering reservoir. You would know if the disk were warped by a shudder when you brake at hight speeds.

I would have the transmission shop check out the transmission.
The transmission may have a soleniod issue.

SOURCE: Buick 2000 Le Sabre-transmission does not engage in any gear.

Try unplugging the electrical connection on the transmission to lock it in 3rd. It might get you moving. Although the transmission is going to need rebuilt or replaced.

SOURCE: OD light is continously on

You may want to pull codes to see what code comes out of computer, sounds like you may have a temp. sensor inside trans. causing this but you will need to get codes.

The OD solenoid in the transmission or the transmission control module is defective. It's also possible the torque converter clutch plates are worn. That's where over drive comes from

Does the 2003 buick lesabre have an overdrive button


If the 2003 buick lesabre has a overdrive button It will be located on the shifting handle at the console. check where your hand is on the handle where you shift there will be a button on the side of your handle push it and watch your dash board where your speedometer is located and watch for any lights or indicator light will come on. or just call your dealer and ask the dealer for information on your vehical.

2000 maxima with no overdrive and code po744 .no tranny slipage in1-2 shift or 2-3 shift,very smooth.the od light works and comes on and off when the od button is pushed.


This code indicates a mechanical problem inside the transmission. Likely in the valve body or the torque converter. He is a description of the cause and a list of possible problems. To diagnose this you need a scan tool capable of reading the trans control module and a pressure guage to read the fluid pressure.

My 2000 Buick LeSabre whines and will not shift into any forward gears. It also has a very loud whining noise. Car starts fine and I am able to put the car in to reverse. Once I put the car in Drive it...


it does sound like the transmission has packed it in. you might be able to find a decent used one via a wrecking yard and get a local mechanic to install it.
try to find one out of a car with under 100K miles on it.
