#80 of 228 2002 LS - Short squeak/squeal when first shifting from P to R.

Hi,
I'm hoping someone can help. I have a 2002 LS v8 with 56K miles on it (bought with 50K). I have had the car for approximately 8 months and it has been a pleasure to drive. However, I do get a short squeak/squeal on most occasions when I put the car into R from P. I do not recall this noise when I purchased the car and find it hard to believe I would not have noticed it then if it were there. This noise occurs about 90% of the time when putting the car in R from P for the first time for the day. Once the car has been put into D it is less liked to make the noise when going into R. Also, if the car has been driven around for awhile it is quite a bit less likely the noise will occur when shifting into R.
I have a Lincoln Premium ESP which will expire at the beginning of December and therefore I have taken the car to the dealer and asked them to diagnose the problem. I had the car with them twice for a total of 5 days and they said they were not able to hear this noise. Finally, last time I brought the car in I pointed out the noise to the mechanic. He acknowledged hearing it but that he felt it was the rear brakes when the driveshaft put torque to the rear wheels. I told him the noise sounds like it's coming from the middle to front of the vehicle to me. He walked around the car while I shifted from P to R and agreed it wasn't rear brakes and seemed to be coming more from the front of the car. However, he said diagnostics all read normal and he checked fluid and it is in good shape. He said given that it is just a short (1 sec or so) noise that it was nothing to be concerned about now and not worth tearing a bunch of stuff apart in an effort to find it.
The car drives fine and doesn't seem to have any problems shifting while going down the road. But, I am from the school of thought that unusual noises do not usually fix themselves and am concerned extended warranty will run out and then some major thing will go wrong and cost me a fortune. Has anyone heard the same noise in their LS or does anyone know what this noise is? Is it really nothing to be concerned about?? Please help!
#81 of 228 2000 V8 - Transmission Issue

When I put the shifter from 5th to 4th...there is a very long lag before it will downshift into 4th. There are not problems going from 4th to 3rd, 3rd, to 2nd. ect.
Also, there are not problems upshifting in any of the gears.
There is just the very bothersome lag when I take it the shifter from 5th to 4th...which i like to do frequently on the curvy roads I drive here in WV. I've had this problem for like 2 years. No other issues, just this one. Any ideas on the problem?

I have a 2000 LS with a 3.0and a 5r55n tranny.problem is about the same as everyone else's almost.Mine slips going into 3 rd gear any ideas.we put a solenoid pac in it but no good was going to try a rebuild on the valve body next, joe

Did you ever figure out what was causing your problem. my 02 has the same problem with falling into neutral, i added 1 1/2 quarts and that seemed to fix the problem for now. was there anything serious that you found out?

we ended up putting a valve body in it.the fluid levels were fine when checked.it seems to be ok for now.yesterday the drivers side window regulator broke.

i have a lincoln ls 3.0 when i put it into d the ass end seems to sink down any ideas?
as well it seems to shift real slow when comming to a rolling stop, almost clunking down into second gear any ideas?

I don't have any idea about the sinking feeling;unless your rear suspension is just plain wore out.the clunking we had and it also clunked when i first pulled out.what was happening the car would not downshift into first gear all the time ;it would only go to third.when you pulled out it would immediately downshift into second and then go through the remaining gears.at least this is what the computer told us.we put a shift solenoid pack on it and that problem was solved.you should have someone hook it up to a diagnostic computer and that will tell them what gears are working and so on.as we drove it came up on the screen with real time trending .

i have the 3.9, but my ass end was sinking down and lurching forward to, but i got that fixed. it is going to do it to some small extent for it being a rear wheel drive vehicle.it could be one of two things form my learning. Lincoln had a memory in its transmission, and the car knows how it wants to be driven. it remembers how it was driven from the previous owners and wants to be driven that way.. if it was driven by a grandma, it will want to be driven easy, and if it was reamed on and driven hard, it will want ot be driven hard.that will also have an impact on how it goes into gear. so have the computer get reset and that should take care of the problem, that took care of mine and it is perfect now. But if that isnt the problem, it could be the RPMs are set too high, that will cause it as well, and that just needs to have the throttle adjusted and turned down. when you start your car, look to see if the RPMs are too high for idle and it could be something that minor. that is just two things i learned from speaking to the dealership that did my warranty. good luck to ya.

Wrong, wrong, wrong. This is an urban myth. The software in the PCM which controls the shifts does not know the difference between one driver and another. All it does is adjust the shift pressure to maintain the factory shift times based on the speed, rpm and throttle position. If a shift takes longer than it's supposed to the pressure is increased - if it's too fast it's reduced. This allows the transmission to adapt to manufacturing tolerances and wear over time to keep shifts consistent. And this info is straight from the engineer responsible for the transmission calibration.
All you need to do is disconnect the battery for a few minutes and that will clear out the learned shift pressures and sometimes that does seem to improve the shifting - not sure why. But it has nothing to do with driving style.
What can happen is you might be hitting shift points that the previous owner did not and therefore the tranny hasn't had an opportunity to learn those pressures. E.g. the shift pressure is different at 30% throttle and WOT.
