In this video I discuss the symptom of torque converter shudder, give an example of it, and talk about the fixes of torque converter shudder.
Torque converter shudder is characterized by a "shuddering" sensation at around the 45 mph mark. This shudder occurs when the torque converter clutch is engaged when the vehicle goes into over drive. The clutch can slip causing a "shuddering" sensation.
Typically this symptom can be corrected by flushing the transmission. Sometimes toque converter replacement is required if flushing the fluid does not work. And then, sometimes, even a transmission rebuild may be required. Consult a certified transmission tech for proper diagnosis.
Toward the middle to end of the video I discuss another option to getting rid of torque converter shudder. This option is a trick that I and my co-workers, co-workers from my day job, use. It involves adding motorcraft XL-3 to the transmission fluid and driving the vehicle. Typically if the shudder goes away after this it would be recommended to flush the fluid as this would most likely take care of the problem.
Note: I have only used Motorcraft XL-3 on Ford vehicles. I do not claim that this will work or is appropriate for use on other makes. Furthermore I do not claim that the use of XL-3 in automatic transmissions on even Ford vehicles is appropriate. I make no claim that the use of XL-3 will not cause damage to your transmission if you so choose to use it for this application. Use this product in this manner at your own risk. Motorcraft is not a sponsor of Barbour's Auto Help and is in no way affiliated with this channel. The XL-3 shown in the video was my own and was not given to me by Motorcraft. Barbour's Auto Help in no way speaks on behalf of Motorcraft. This is just a trick I learned. If you try it, do so at your own risk. By the way, there are other products out there that do claim to fix torque converter shudder. Do your own research.
Note: Some vehicles can activate the torque converter clutch at speeds other than 45mph.. Also, in some rare instances torque converter shudder can feel very similar to a misfire. This video is not a "one size fits all" video.
