Re: P0401 causing transmission problem?

I doubt the first two codes caused a slip...sounds like 3 separate problems.......first two codes would not cause a slip....

Need to do a road test with a scan tool attached........watching slip data, and output vs input rpms in the tranny.......

The other could be a MAF or vac leak problem......

The EGR could be another separate problem....a bidirectional scan tool would verify EGR opening and flow and position.....
