2000 Yukon Maintenance Question

[MrBalll]

If it was me I would replace the fluid and filter. If you drive it around and it doesn't crap out before your Florida trip then great, you made it it through.

It makes no difference if you drive a a vehicle with 25 miles on it or a vehicle with 225,000 miles. Failure can and will happen. It's just how things are. Just work with what you have and change your fluid and enjoy your trip. Don't let failure clog your head. I drive my 13 year old Tahoe everyday and have no cares about it failing. Don't treat it as a drag car and you should be fine.

Everything is up to you. If you take the advice of forum backyard mechanics then that's your choice. You have the final say.

Best idea yet.

Thanks. I'll change the fluid and filter, drive it every day for a month and a half, and either leave with confidence, or with a new transmission.

Having looked at used vehicles on the Internet, people really put the miles on Yukons and Tahoes. Ours isn't all that high.

Oh yeah. If you care for these vehicle they will last.

In your case the way I see you can either fail now and fix the transmission or fail months or years from now and fix it anyway. Better now than later so you have that peace of mind it's fixed.

Got the tranny and radiator serviced yesterday, and I will use it as my daily driver for the next month.



On Carfax the other day I saw a lower mileage Yukon XL in Naples, FL that would make a nice replacement. I'm sure if I'm more diligent finding a replacement than I was servicing the transmission this time, I can find another one that will last us 18 years.

 

[NotJLB]

So far, so good.

Speaking of Carfax, I've been looking at the Maintenance History on a number of 100,000 mile Tahos and Yukons, and I haven't found one yet that serviced the transmission.

Unfortunately, not everything is reported in carfax, especially maintenance sites. I sure as heck don't log anything electronically when I change the fluids on my vehicles, just log my personal logbook.

Let me say it this way . . . There are plenty of service reports . . . oil changes, window regulators, etc. Just no "transmission serviced".

Sample:

01/23/2013 61,244 Premier Auto Service Of SW Florida LLC(
Cape Coral, FL
239-471-7049 Rear brake pads replaced
Rear brake rotor(s) replaced
08/06/2013 63,533 Premier Auto Service Of SW Florida LLC(
Cape Coral, FL
239-471-7049 Oil and filter changed
Wheel speed sensor(s) replaced/repaired
07/24/2014 67,020 Premier Auto Service Of SW Florida LLC(
Cape Coral, FL
239-471-7049 A/C compressor serviced
A/C compressor replaced
A/C refrigerant recharged
A/C system checked
A/C system flushed
A/C system serviced

From that same vehicle:

10/06/2011 50,770 Dunning Motor Sales
Cambridge, OH
740-439-4465
dunningmotorsales.com
Maintenance inspection completed
Transmission checked

The mileage is right for "transmission service", but it was just "checked".

& that's the only one I've found that even mentioned the transmission, when they are listing other specific services.

Transmission 'service' is definitely a scheduled maintenance item. A lot of people choose to forego as to spend that money on something else. I have purchased several trucks over the past few years that are of the 2003-2006 range MYs with +\- 100k miles and im not comfortable driving the vehicle until I change the trans fluid out. The newest chemicals are far superior to those factory filled or that of 10+ years ago- much higher threshold for "operating" temps. Dexron6 maintains stability at temps where Dex3 would begin to shear and the synthetic properties provide lubrication at the micron levels where Dex3 is unable.

I started running AC Delcos newer 1dexos synthetic motor oil for the same reason: its just far better than what was in it before and provides better protection, which you need to keep a 15yr old vehicle running daily at minimal cost.

Good idea to flush the power steering fluid out, too. Wait til you compare the original fill with a new 1. If you thought folks neglected the trans' what do you think about that?!

About the same.

If we were in FL right now, I'd be buying the 2005 Yukon XL, with a super-clean 2-owner Carfax report, and 77,000 miles, for $11,900. The first thing I'd do is have the transmission serviced.

 

[Chubbs]

Haha!
If people would just spend the money on a 40k mile flush and then do a regular, old drain&fill with filter replacement every 50k afterward, the trans will last the life of the vehicle, especially if the cooler is upgraded and you don't drive the truck like a formula-1. Any actions contributing to the overheating of the unit is what's most detrimental.

But I don't need to tell you. What is yours now? 230k miles on orig trans?
