I have noticed some transmission fluid in my vacuum lines and hope that the issue is caused by the Transfer case switch. My question is, does anyone knows the Delco/Delfi part number for one or is the Dorman Part just as good? Thanks.

 

Did you ever use Rockauto? That's where I would go..

 

+1, can't beat there prices

 

yep..first place I looked at and they only carry the dorman part. maybe delco stopped making them.

 

Actually I doubt delco ever did make them.. but if RA only sells Dorman it's probably a good part.

Yep.. I'd go with RA - Dorman for $17

Guy on ebay has no-name for $20
