The transmission in my 04 Yukon finally crapped the bed back in February. Wife was driving it on the Interstate when it started revving to 5000 RPMS and wouldn’t get passed 50 MPH. She called me and told me what was happening and I told her to turn around and try to get back in the driveway, which she did.
I tried to go around the block with it that following weekend and that was a no go. Sounded like the pump was screaming and the fluid was burned and nasty. It had been slipping when shifting into 2nd gear for a while and it finally said no more. I bought my wife an Acadia back in 2019 when the Yukon trans started acting up so we got extended borrowed time on it.
I called a few shops in my area to get some quotes. $3500-ish was the ball park with a low of $2800 and the Chevy dealer being over $4000. Beyond the pricing, it is hard to find a good shop in my area that you can trust do the job right. The dealership was just too expensive for my 200k miles Yukon.
I then started to contemplate doing it myself and looked online for shipped to my door prices. Enter Summit Racing… They have an exact fit new transmission for our trucks that will support 450 HP and is advertised as correcting all of the factory defects that the factory ones were born with. The case and bell housing are stripped and painted, the guts are brand new, and they throw in a polished finned trans pan with a drain plug, all for the measly price of $1749 shipped to my house on a FedEx lift gate. I was sold. The only issue I had was the back order for the trans was excruciatingly long. I ordered it in February and got it in mid May. I ordered a converter from a reman shop in KC. I ordered a couple of parts from my local Chevy dealer and I ordered all the rest from Rock Auto.
I came in at approximately $2800 with all the parts I replaced and my labor. I had no help and spread it out over 5-6 days working here and there. The truck runs great and that transmission from Summit, so far, is worth every penny. Got about 175 miles on it so far and it has been great. I replaced the radiator, factory original, the trans lines, and a bunch of other stuff. Attached is my parts list with vendors, part numbers and prices.
