My S60T5 2001 has 75000m
My transmission was working fine until yesterday morning.
First cold day of the year! When starting the car, I get now a very rough shifting from 2 to 3 !!!!! The balance is ok....no slipping also!
I check the oil level ok .The oil is a bit dirty ( I was thinking to replace it for a while now!!!). But Volvo said lifetime oil !!!!!!!!!!!!!
Replace it only if you have problems!!!!!!!!
Anyway it could not be that causing this problem so suddenly!!!
I disconnected the battery for few hours and reconnect it back... (to try to check if it is not the TCM sofware causing that)...
The 2 to 3 hard shifting still there but it seems to be a little bit softer....
Volvo dealer can only check my transmission software in 2 weeks....
So , I need your expertise!!!!!!!!!!
Thanks in advance

 

Do a tranny flush before anything! I would highly recommend using a quality synthetic which will help your tranny out greatly. As for lifetime fluid? thats total BS in every which way!

A word to the wise, stay FAR away from the dealer unless you are buying parts are have free warranty work to be done.

 

Thanks to all of you for your help......
My transmission serial number start with 01E.....
I'd just finish my flush.....
It improves a bit (all is smoother) but I still get the 2-3 non-smooth shifting !
Now my last chance will be a software upgrade!!
Do you think I could add something in the oil also?

What did you use for fluid and how did you do the flush?

 

After having read a lot of discussion about Volvo ATF oil...I have used 12 liters of Toyota T4...(It's a Aisin Warner tranny ,made by Toyota!!).
I undo the drain plug,about 3 liters of very dirty oil dropped..Then I put it back , disconnected the upper return cooler line and ..started about 5 times the engine ,to evacuate about 1.5 liters of old and brown atf each time while I was pooring the exact same amount of atf through the dipstick of new oil.
At the end the oil was red and very clean!
I just have to check exactly now my oil level....(when cold and hot)

 

I would still flush it out and use synthetic as it tends to shift smoother and keep the tranny cooler... just my opinion though.

 

Hello Binglax
How are you?
You know what was the problem?
B4 cover !!!!! Now tranny works like new one....

 

haha yeah that would do it right there...
