I have 60k on an '03 s60. No real issues with transmission, but have noticed that it will occassionally get stuck when going up a steep hill or travelling up a prolonged (half mile, or so) incline.

Can I use the Lucas Oil Transmission fluid as a preventative? Any other ideas? Thanks.

 

I'd do a full flush with Mobil 3309 or another 3309 fluid of your choice.

 

Have u replaced ur fuel filter lately. That could be the culprit or the fuel sender may be bad. Do a pressure test and u should get between 35-55 psi
