i have a 2002 s40 arrow flashing on dashboard. checked codes and got slt solenoid signal missing. transmission shop checked solenoid and transmission computer and told me it was good. anyone with same issue? what else can it be?

 

You have not perhaps put her in Winter mode by mistake?
Try pressing the 'W' button a few times and see if that fixes it.

 

W mode is a steady arrow I believe. The flashing arrow is trouble. I once caused it when I had the front jacked up and ran the car in gear. I had to clear the code with a scanner to make it stop.

 

i tried to remove the code but after a day it came back... i already found the problem. there was a cut cable coming from the transmission. it fixed the problem of the flashing arrow but now the transmission gives a hard shift when i put it in drive or when stopin going from second to first gear... any advice on the hard shifts?

 

maybe she is due for a transmission fluid change.
A 'drain and fill'. 3 quarts x 3. Not a power flush
Refilling using a JWS.3309 spec fluid only.

 

thank you for your help, will change atf as suggested 3 times. i was wondering if a transmissioan treatment fluid will do any harm or any good?

 

I personally would not add any of those treatment additive products to my newly refreshed ATF.
Let her settle in for a while after the change.
Most report significant improvements with fresh ATF of the correct type after a period of running unless there are other issues causing problems.
If the solenoid etc tested okay as you have said above its likely / hopefully? just due for fresh ATF.
Does the existing fluid look dirty on the tranny dipstick or smell a bit burnt.
Should be a cleanish red colour.

 

yes the fluid was almost black... thanks for the advice... i also encounter another question... does a 2002 s40 have a transmission filter... i found a few post about volvo 5 speed transmission not using a filter... do you know if that will be true... i will try to check my car during this week... thanks again.

 

I've not read of anyone changing a filter so I looked at RockAuto and found a part and picture. Has anyone changed this before?

RockAuto Parts Catalog

Do a part number search at the top (or go through the menus): 5441506

 

I believe and have read that those in line filters are commonly added by some owners to provide filtration and a longer ATF fluid life.
Its optional so if you can afford the extra parts and time why not.
You should see improved shifting with clean fluid itself after a drain and fill procedure.

 

already change atf but still same issue with hard shifts... getting obd2 code p0700... will have to get it check out at dealer... already found where the filter goes but is inside the transmission... unfortunately i haven't found a volvo mechanic in my area...

 

did you ever get to the bottom of your p0700 code?
