I’m having the shop that put the 2004r trans in my Chevelle replace the what I think is the original WP on my work van with a 4.8 V8, I told the shop owner I wanted an AC Delco Professional WP he said I’ll call you back with a price, called back with $708, I know the WP is around $100 or less but I’d rather pay a shop to do this job and my auto ac friend said he’d do it for half that amount but in the summer I practically live in the van lol so rather have a shop with some type of warranty do the work, so $700 sound reasonable?
