IDO, this is the Grouse. Over. We have a giant vehicle charlie foxtrot situation. Over.
The (very short) version. Waaaaaay back in April, my 2013 GMC Acadia (158k on the clock) started jerking when accelerating through 3rd gear. The situation rapidly got worse and then included shaking in 2nd gear.
Took it into the local independent shop that I have used for 20 years. Diagnosis: Bad tranny. Very common, apparently, the 6 speeds in these GMC/Chevy vehicles are known to be junk and rarely last longer than 150k. No new or rebuilt trans units are available anywhere nationwide.
The only option was to send trans out to a local shop for rebuild. Which I did to the tune of $6500. First rebuild attempt took 2.5 weeks and the result was that tranny died again 3 days after I got it back. Rebuild #2 took 3 weeks due to parts shortages. This time the rebuilt trans had issues from the first time we drove it. I kept driving it and issues got worse so it went back. Shop tried it and blew the tranny on their test drive. Ug! That was 2 weeks ago.
Shop called today. Trans shop attempted rebuild #3 and put it in yesterday. On the test drive, trans failed again. They say they simply are the victim of bad parts and parts are so hard to find that they can’t source parts they’d usually get. They have tried to search for a tranny nationwide and there are simply no rebuilt or new units available. Calls to dealers indicate that current wait times for this transmission are 4-6 months.
In fairness, I believe both my mechanic and the tranny shop are acting in good faith. They have rebuilt this thing 2 times at their cost with no result and they have offered to refund a more than fair amount of the 6500 I paid. But that still leaves me with a dead vehicle that can’t even move under its own power. My local mechanic has used this transmission builder for almost 30 years and never had anything like this happen before. The mechanic has contacted other transmission shops and they won’t touch it due to lack of available parts, they all say “get a reman or buy a GM new unit”, which of course would be a great idea if one were actually available.
What the hell does a guy do in this situation? 2013 GMC Acadia SLT, 158k miles, transmission totally shot, everything else in great shape, runs great, uses no oil.
Shout out to Sheldon who has given me great input and encouragement throughout this long mess.
