Tranny rattle??

[twistedpreddy]

I just bought a used 1999 f-250 with 133k miles and a 6speed manual tranny. the prob is when im in 1st or 2nd just crawling around in a parking lot or anything really low rpm's there is a rattling comming from the tranny area, ive been told standards do that and its normal. anyone know what im talking about?

It's the dualmass flywheel....or the bearings are shot. Is it only in first and 2nd? How about when you get going...like in the higher RPMS in 1st and 2nd?

Sounds like just the dual mass chatter...but it could be more. (I'm VERY leary of my Manual tranny now...)

ya, its just in 1st or 2nd. when you get goin in higher rpm's its fine, no probs at all. what is the dualmass flywheel? whats the diferance to a regular flywheel?

[Ditty]

Ford just put in a Flywheel that is sort of like 2 pieces. You can go with a single mass flywheel and clutch kit and it will go away. I recommend Southbend.

I wouldn't worry about it too much. If you wanna get rid of it, going singlemass is the only way. Talk to Patrick or Larry at Discount Performance Parts. They hooked me up with my Southbend clutch in August. I love it.

Ohhh...and WELCOME TO THE .ORG!!!

Is this rattle something I need to deal with or will it just keep rattling for a long time...?

I call it "tranny rash" and my 2000 has done it for the whole 4 years ive owned it. My old 1994 F150 did it as well. Im not worried about it.

I have narrowed it down a little since the last post. It only accurs in first and second gear, not in low or any of the high gears, some friends think it might be shifting fork related...? does anyone else have the same funky rattle !

sounds like gear roll over in the tranny, mine goes away when i give it a little more gas when letting clutch out. only happpens in first when crawling around a parking lot. suppose to be normal and not a real problem, lots of guys have the noise. make sure your oil level is ok.
