Check the transmission fluid, also smell it tosee if it smells burnt, to answer your question, they don't have anything to do with transmission slip. I hope this helps. take care

I smelt fluid it didn't smell burnt or anything. Fluid level fine. Thanks . Guess I'll have to take to tranny shop.

I put old maf sensor back on and slipping went away. Now it shifts into gears hard. But it drives better with old than it does with new. Any reasons?
