Yes there are 2 relays in the box you should change out. The smg hyd pump is 61366901469 and Tischers price is 10.94. Of course this one gets a lot of hard use. The other one is the smg transmission oil pump which moves transmission oil through the cooler. That one is salmon color and it's part number is 12631742690 for 6.94. Since I'm in the relay box anyway, I change both when I do spark plugs. I always buy 2 each so I have a spare in the garage. How many times have we read where someone is left walking and their car is flatbeded to the dealer just for the burned out relay. I think they should be changed often, they are cheap.
