So my “new to me” Tahoe has 221k on the clock. I’m calling the last shop of service recorded on Carfax (213k was the last service back in February - shows as oil change and tire rotation) tomorrow with hopes to get some input on the service history of the vehicle. Records show they’ve done all of the regular service since 54k miles back in ‘14. Before that was all at the local dealership it was purchased from new. The only exception being a torque converter replacement at 76k miles, which was done at the dealership.
My intent is determine if the service shop, which is also local, has done any transmission maintenance, ever. A couple of the entries on carfax just show “vehicle serviced” with no detail, whereas all others give some detail of the services performed. None of the service details indicate a trans service.
The question I have is this, should I change the trans fluid and filter if it hasn’t been done since the torque converter replacement at 76k? The dealership confirmed For me today that they did replace the fluid and filter along with that service. I’ve heard/read plenty of anecdotes that you shouldn’t change the fluid if it’s never been serviced or hasn’t been serviced over 150k miles (which I’m coincidentally right on), otherwise this will cause the trans to fail in short order for various reasons. It feels strong and shifts great for what little (150ish miles) I’ve been able to drive it over the last few days I’ve owned it.
If that’s the case, should I just plan on replacing the trans to remedy this? This is a second vehicle I use for work travel (I’m an engineer that visits project sites and clients), but I plan to start towing with it soon too.
I’d appreciate some input. Thanks!
