Re: Rattle in automatic transmission

["jtrealty@xxxx " <jtrealty@xxxx>]

I'm a little confused, first you said the rattle stops when you hit 
the brakes then you say it rattles when you brake. On the subject of 
the transmission noise first I would do as many external checks as 
possible. Some of the things to inspect are the following; all 
mounting bolts to the motor and the frame, the oil level in the final 
drive, the c-v joints and the bolts, trailing arm bolts, remove the 
cover and inspect the torque converter and the bolts to the flywheel, 
the fluid level in the trans. If you cannot find the cause externaly 
then you might have to consider removing the trans, final drive, 
torque converter unit because a rattling noise from the transmission 
is not normal and could be a sign that something is comming loose 
inside. A rattle comming from the front of the trans could be an
early 
sign that the c-1 clutch pack is broken. This is a common problem,
the 
c-1 drum is only spot-welded together and the spot-welds will break 
from a bad shift computer or driving very hard on the auto trans. 
Remove the pan and see if you find shiny metal particles. A small 
amount of friction materiel is normal but metal is not. You might
even 
see some metal particles on the dipstick but the magnet in the pan is 
supposed to catch them. If the fluid smells burnt then you wiped out 
the trans and it is time to pull it out.
