F150 shudder

================================================================ I had a 91 Bronco 4WD with an E4OD trans. It started shuddering when the converter locked up. I changed the fluid and filter, and the shuddering went away. I sold the truck to a friend and now 2 years later, no shudder. Give it a try---It's cheaper than a converter replacement.

You probably have the 4R70W transmission. This transmission, among others, is succeptible to shudder when the transmission fluid isn't maintained regularly, i.e. replaced. That's exactly where I'd start.

There's a sticker (placard) on the door jamb that will have a transmission code on it. You can then search online to see what the code means for your year. Sometimes the owner's manual will explain the codes for the transmission and/ or axle in the towing section since they help determine the towing limits.

Sounds like converter clutch is getting thin and chattering on engagement. At very least you will need to replace converter.

Not a bad place to start if the fluid has not already been serviced.
