Hey guys so here is one for the pros.

I have a clutch that seems to be slipping when the car has sat a few days. It will slip in 4th 5th and 6th under load especially if it's very cold out. But then if I drive it a little aggressively it will stop slipping for the whole rest of the day. I've never had anything like this happen. It's almost like the pressure plate isnt clamping all the way down and then it does. I had low pentosin in the rear reservoir and just refilled it to see if the slipping stops.

I also have a boost leak that comes and goes.

Any ideas on these?
