12 speed leaking air..

Recommended Posts

My 12 speed shift knob is blowing air out the exhaust port in all gears except nutural,I suspect a bad o ring right,do they make rebuild kits or do I hunt down the o rings separately,or buy a new shift knob?

There is a kit for rebuilding it.

The old Mack number was 14RC1131 for a knob rebuild kit.  Can't help with what the new Volvo number might be. 

PAI has a rebuild kit as well.

I bought a new knob 6-8 years ago and it was $350.00 just to let you know.
