hi all my cars gears change slower than they should, it is more noticeable when changing from second to third and third to fourth
anyway i think i should get the fluid changed afterall the car is at 160k and has never had a fluid change. everyone ive rang so far keep saying its a sealed box and doesnt need a change, just wondering if this is true?

any help is appreciated.
 
The 722.9 (7 speed) is different from the earlier 722.6 (5 speed) and is filled from the sump. Not an easy DIY

Find yourself a good indie and get the atf changed
 
You know it makes sense! :)
 
Hi thanks guys was just making sure as some of the guys "transmission specialist". Will get it in at some indys
