Hi,

My torque converter went out about 10,000 miles ago and I had it replaced. Transmission tech checked everything out while he was in there and said everything looked good. He replaced the fluid and filter also. Now, I've got the 5-3 "Squawk" happening. The first time it did it was shortly after the repair. Currently, just about every time it shifts from 5 to 3 it squawks. I have seen two places online where ford has said to add the additive if all the fluid is replaced. The first was for a 2015 Mustang and the other is a 2014 F150. I just ordered a tube of the XL-16 6R ATF Additive. In your experience, is the additive going to fix the squawk for good.

Good afternoon,

It sounds like there is dirt or debris in the valve body causing this issue. The additive is for the valve body which tells me the converter put more debris in the transmission than thought.

I would have rebuilt the transmission if it was me. These are the type of issues you get when you replace just a single part with 100,000 on the rest of the transmission.

Add the additive and see if it works. If it does, that is great. If it does not then the valve body will need to come down and gone through.

That noise sounds like the torque converter itself. I would have it confirmed by someone. There may be debris in the converter from the original replacement.

Roy I attached below the procedure for replacing the converter itself.

Let us know if you have any other questions.
