Question about 2005 Mercury Sable

1 Answer

At 40-45 MPH it feels like the Torque converter is trying to lockup and really can't tell if it does or not . Feels like a surge forward, does it once and then OK for a while Car has been sitting for two days in VERY cold temps. Could it just be icing up somewhere or is the Tranmission ready to go ? Thanks

    I had it flushed at about 50K. I may end up taking it in, Are you aware if they can run a computer check on this to see what the issue is ?

I would recommend having the transmission flushed. what usually happens is condonsation build up inside eventually becomes water in the trans. then it gets into the torque converter. eventually it destroys the torque converter.

    yes, they should be able to read when the torque converter locks and unlocks and if it is being told to or not.

It wont go over 30 mph without reving up to 3000 rpms


Look at the torque converter on the transmission first. If it checks out good then look at the transmission for problems. A diagnostic test will provide some insight into internal transmission problems.

I have a 1500, 5.7, 2 wheel drive with a 4 speed transmission with O/D . How many times should it shift including the O/D and what does the lock in torque converter have to do with it?


It should shift 4 times. 1-2, 2-3, 3-4 Then you will feel the torque converter clutch lock up which feels like a shift. The torque converter locks to increase gas mileage.

In overdrive it feels like my torque converter isnt locking in. Any suggestions? It is an 02 silverado and normal rpm at 70 mph is 2000 and now its running at 2300


It is possible your lock up torque convertor has a bad connection or wire.
You should be getting a check engine light on in your dash.
You will need a OBD II reader plugged in to retrieve code.
Please let me know.

Shifts in and out of overdrive


This sound like you are feeling the transmissions torque converter going in and out of lock up. When the torque converter goes into lock up it feels like a shift . One way to tell if it is the converter you are feeling is to push the od button disabling overdrive and see if it still does it. The converter will still go into lock up .

Overdrive transmission


you have an issue with the torque converter clutch, your symptoms indicate this is the issue, possible TCC solenoid problem or the torque converter itself has a shorted magnetic clutch.
