Hi

I am driving a 2001 S60 2.0T (FWD) and recently discovered a new problem. In the mornings, when I engage the auto transmission to D, it takes like 2-3 secs before it will engage with a jerk. Someone I know told me that this is a common problem with the s60 and has to do with a sticky/faulty valve body. Anyone can help?

Thanks

Yes it is a common problem with the S60's.It could be as easy as a software download.It could also be the valve body.Is the car still under warranty?If so I would take it to the dealer and complain.It could also have something to do with the nuetral control function.In that case they would download software to remove that function.

Hi Tech

Thanks. The car is not under warranty and I already had the neutral control removed and the software reset. After the reset, it was fine but then the problem came back. If it is the valve body, is that going to lead to bigger problems and if so, how soon shall I fix it.

Thanks.:(

I would have it fixed soon could lead to more bigger problems.That is about the only part the dealer replaces they dont rebuild transmissions.A new trans is about $2000.00 plus the labor to install it.
GOOD LUCK let me know what happens.

Ok thanks. How much woudl it normally cost to replace just the valve body in your country?

I will check and post tomorrow.

Hi Tech

I've recently got a new problem. The last couple of days, the transmission started to slip and the car became sluggish even though the engine revved hard. This disappeared when I stopped the car and restarted. I'm deciding if I should repair or get rid of it. Is this already a sign of more than the valve body fault already? How extensive could the problem be and will it be OK if I fix the valve body?

Replacing the valve body should fix it.I cant say 100% that it will fix it but it should.Do you have any extended warranty?

No. :( Can you sort of explain why this is happening apart from the delayed trans engagement? That I understand is because the valve body is sticky and thus the pressure required to engage is insufficient or something like that?

You pretty much have it already.The valve body controls fluid pressure to the gears and if something is weak or not working properly the pressures will be off.These transmissions are very picky about pressures.You can thank GM for that.

So without the pressure the gear is slipping? This part I can't grasp???

Yes with out pressure it will slip just like if it was low on fluid causing low pressure.

Thanks.

No problem

One more question. WHy is it that when I restart the engine, it becomes normal again?

I believe it is because the computer is trying to do a self test to see if the fault is still there.

This means that on restart the computer did not detect anymore fault?

Maybe not rite away but all the soleniods get tested while driving.If it then acts up there is still a fault.

I know it doesn't go away for long. I have accepted the fact that there is a fault.[&o]
So when I restarted and it went away, so fluid has then flowed in and the pressure was normal after the restart (at least until it acts up again)?

Yes that is how it works.

Hi Tech

Got my transmission valve body replaced. Went smoothly for a a couple of days but last night, it started slipped again for a while. I depressed the accelarator and it didn't kick down like normal. I floored the acelerator and it kicked down quite aqbruptly with some clanking noices and it went normal again. What do you think could be the issue? Could it be the transmission control adaption?

Do you know if they test drove it and reset the adaption?It could be the adaption.There is usually a process that has to be done after replacing the valve body.It usually takes about 5-10 miles of the tech driving after putting into adaption mode.

Yes they did. But I think the probelm I have may be something else. I suddenly experienced a loss in power and although the gear changes were normal, the engine seemed to rev more while the car was sluggish and there's sort of a whirring noise if i rev past say 4000-5000 rpm. Also I noticed some white smoke coming out from exhaust. Do you know what this can be?

Sounds like the transmission is slipping.There isn't much more I can say thats what it sounds like to me.If you keep into the gas when it does that does it slam into gear?Or does it kind of slide into gear and than go?

It doesn't kick into gear. It sort of is sluggish right from stationary and the engine feels like it's lost its power. Then it moves on to the next gear when it gathers enough speed but then if you try to depress the accelerator, it just doesn't have the pulling power it did, but the engine is howling.
