There is a couple of things you can check first see if you have any brake lights . If you dont then its the brake light switch thats behind your brake pedal

i already did change the breke switch, but istill doing the same thing

not really a car this old sounds like the transmission needs to be rebuilt or replaced. You can try an additive live lucas transmission stop slip and see if that helps for the time being, but remember you need to check the fluid level and remove some if it is all the way up before adding the quart of stop slip

You have an Axle problem probably, the best thing is to replace the Central bearing too as you already replace the Flex disc, and check the Sleeve Yoke Spline and shaft if worn, you have to replace it. Check for any loose bolts & nuts to the Axle assembly. This is the most common problem that you may check and replace for the noise.

There 2, one for the front and back

Your transmission slips or won't go in reverse? Low Transmission fluid is the common problem of slippage, refer to your owner's manual, find the location of your transmission fluid dip stick and check the fluid level. Add fluid if low, and test your transmission for a few miles of rides. It's just for the fluid, try it if it works.

Inspect your shift linkage it may be loose/wear or incorrect adjustment. Also check your transmission fluid refill if necessary.

The most important thing in A/T vehicles is the fluid level, most people have this problem only to find out they just need to top off their reservoir (hopefully it hasn't done any severe damage to the drivetrain) check it first, if it is full, then there is something wrong with your transmission.

Any symptoms prior to this? Usually what happens to other people is one (either drive or reverse) goes bad then both.

Also the bands in your tranny might have been stretched or it can also be that your torque converter has gone bad.

Before this happened to you, when you select DRIVE, does the car move by itself without you stepping on the gas?

Not sure how that would have happened? is it like a dry rought hole, or is it something possible damaged it, or i a spot where it was rubbing up against something? There should be just the hose you can replace. What do you mean by the whole component? If it is a seperate rubber hose attached with clamps on both ends then you will be able to replace just the hose

That's one of my favorite cars by the way
