Will this effect my warrenty for a coolant leak and possible a slipping trans

 

It sure could.

Ported or descreened MAFs change the air intgake input and then the PCM will usually adjust line pressure accordingly which usually translates into sluggish shifts. A slow shift will build heat in the trans and cause premature failure.

 

D'oh!

 

FBLPONY, so you mean since I have taken out my MAF screen, it is hurting my trans?

 

No, I don't mean it IS hureting your trans I am just saying it technichally can. All the dealership needs is a solid techinical excuse to void a warranty and right there they would have one. Just like the whole K&N filter oil issue with coating the MAF wires and changing the input the PCM reads and screwing up the tranny.

I have not had a screen on mine in awhile and it never hurt the trans but now I am gonna try and borrow a stock one and see if that solves my nw shifting problem

 

Well I am Going to reinstall the stock box and Borrow a buddies 04 mass air but I will still have a ported tb on it though

 

That would be a fked up dealer to void a transmission warranty for a k&n filter.
