Noisy Convertor?
|
Alright people, thinking caps required... I have a '99 (4/98 build date) F350 4x4 with the diesel. 128k miles on the 4R100(?). It makes a rather obnoxious grinding/rattling sound at idle, and shifting up through the gears. As soon as the trans shifts into OD, it gets nice and quiet. When decelerating, as soon as the converter unlocks, the noise starts again. If I pull off the pavement into grass, it gets markedly quieter.
Can this be anything other than a noisy torque convertor? Should I get one now, for when it finally quits, or is this noisiness normal with this trans/engine combo?
I also understand there is a way to install a manual t/c lock switch on this trans. Anyone have a schematic or working drawing of that mod?
Thanks for any ideas!
