1995 crown vic acceleration issue

[mcdlnwright]

Ok heres the new issue and I cant describe it technically because well I'm not that good

You know when your driving on the highway, and you get too close to the side of the road and you hit those groves in the side of the road and it sorta vibrates you a little?

Well when I was driving a few months ago my car did that and i was like darn when did they put these on regular streets.

and it did it every now and then, so i figured it was me so i made a point to dirve in the center. then one day i noticed it only did it when i accelerated. so one day it started doing it so i let off the gas and it stopped.

So WTF? I cant figure this one ut what could it be

HELP AGAIN!!

You probably need the torque converter and transmission completely flushed. You are feeling the torque converter shuddering. You can either take it to a shop or do it your self. If you want to do it yourself, it can be kinda messy. Let us know and we can help.

well that depends Is it a very expensive thing to have done at a shop? Because honestly if its rather cheap I would rather someone do it who wont screw it up.

But if its a rather simple thing I can try it. I'm still a beginner bt I have a Chilton's book

I think most places charge around 100$, more or less. If you do it yourself, you need to purchase 12 quarts of fluid, filter, cleaner and hose to flush radiator cooler. Price the parts to see if it is feasible to dp it or pay to have it done.

Is it very hard to do yourself?
Most of the places I called wanted upwards of 100.00 to do it and allot of them seemed to hint around to the fact that they will just drain the trans and call it good. what is involved in a flush?
is it like changing the oil?

Go purchase a transmission filter kit, 12 quarts of fluid and a transmission cooling line flush kit. You need to remove the trans pan, catch all the old fluid. Remove the filter and replace. Replace the pan. Gashet should be reusable. Just clean it good. Remove the little rubber plug from bell housing, spin engine over by hand until you see a small plug in converter. Remove the plug. There will be about 8 quarts of fluid come out of it. The plug needs loctite on it when re-installed. Be careful not to cross thread. Remove both cooler lines from the passenger side. Hook the flush hose to one of the lines. Spray cleaner until it is empty. Use compressed air, if you have it, and blow all the liquid out of the lines. Hook everything back up, put about 5 or 6 quarts of fluid in the transmission. Start engine, move shifter through all the gears a couple of times. Then add 4 more quarts of fluid. Do the same thing with the shifter. Check fluid level and top it off. Have fun.
Call your local dealer and see if they have a special going on for the flush. They will do it completely. Good luck.

Wow 100.00 doesn't sound so bad after all.
My dealer wants 175.00 so I don't thin I'm going to them. I will call around some more but I think this one will be done at the shop.

I may look into doing the brakes on my own. I just need to figure out how to tell if its the pads or rotors

[mcdlnwright]

Took it to a shop today and they tried to talk me into a trans rebuild. They claimed that I could actually do more damage doing a flush because its a higher mileage car. 150,000
It shifts great its just that vibration when I'm acceleration.
Another shop recommended I just do a simple Trans fluid change and change the filter. They claimed because I didn't know the past history of the car and if it was serviced correctly I could damage the trans, They said that the new fluid would be slicker and could cause the trans to slip..??????

Ok now I'm thoroughly confused?
Btw I read a article and it said that when the vibration happens to tap the brake lightly and if it goes away or lessens its the clutch. I did that and it did.

So does that re enforce the flush theory because a regular change wouldn't touch the fluid in there?


Like I said I am more confused now than ever.

HELP AGAIN

Change the fluid and filter and purchase a bottle of Lucas Shudder Gaurd. This has real good results. WHen you put your foot on the brake, you are disengaging the lock up portion of the converter, not the clutch. Unless thay said the torque converter clutch.

[mcdlnwright]

they did,

I will try that first. Do I still need to drain the fluid from the clutch or just the primary pan?

[way2old]

You can try just the pan and filter if you want. The shudder guard is pretty good, but the more old fluid that is out of the suystem, the better it will work. We have used it without changing any fluid and it stops the shudder. We also change the transmission fluid every 20,000 miles due to the way the local Police drive them.

[mcdlnwright]

ok i'm also going to try to get to the bolt on the clutch and drain that as well.
How much fluid will i need and what type? the guy at auto zone said i need the exact original type unless i get it all out?
Is it hard to get to the bolt on the clutch? and will it simply just drain out.
What i mean is I was told one type is better than the other.
But if just taking the bolt out doesn't drain it entirely out i will stick to the original type.

[way2old]

If you are going to drain the converter and change the filter, you will need approximately 12 quarts. When you put fluid in, add about 6 quarts then start car and run it through the gears. Place in park and add another 2 quarts. Run through the gears again. Place in park and add 2 more quarts. Place in park and allow to warm up fully. Then fill up to proper level. Drive around the block, come back and check fluid and top off ad needed.
