Consensus on transmission service interval?

[homesick]

I’m not really sure how to respond to the last three comments other than I’m glad the stock tires have been changed out for higher performance tires.

I think everyone’s level of comfort with trailering is different and speed should be approached from conditions given in the situation.

Trailer safely and within the abilities of your vehicle. Arriving late is better than not at all.

I hope he doesn't live around here. It's just a matter of time, and he'll probably take some innocent(s) out, too.

We have roads, where we drive like this

Its my video, more over, on such roads accidens less than on usual roads

It sounds like you're young. "It's ok, I've done it before" doesn't work forever.

I am definitely talking about traveling on highways, where conditions and conditions allow this. We are very active in the construction of such highways that allow you to travel between large cities at a speed of 100-110 miles per hour for 400-600 miles in a row)

Sounds like a great way to get from one place to another. On well designed roads I enjoy driving at a good pace. Also sounds like you got the right tires for the job.

But, I'm too cheap (frugal?) for the most part, so if I don't have wind, or good traffic flow, to assist with the wind drag reduction I get too pissed off at the drop in fuel economy and decide to keep it in a happy zone and take a few more minutes to get there. But 100 mph is is fun to cruise at in good conditions.

But that's not the point, we always have cars in the left lane driving over 95 miles per hour on these highways. My previous car was a Mercedes GLS, I drove it on such highways at a speed of 125 miles per hour, and the distance between cities is 400 miles in 3 hours and 45 minutes

We have a very large country, and the distance between cities is quite a problem. And we found a solution to it. We built toll highways where we made a speed limit of 81 mph. That being said, we have a non-punishable 12.5 mph overspeed. Thus, you can drive at a speed of 81 + 12.5 miles per hour on such toll highways, it turns out that 93.5 miles per hour is allowed by law and you do not get a fine. But in addition to this, there are no speed cameras or police on these highways, and it turns out that there is no one to record speeding, and on such highways you can drive at a speed of at least 200 miles per hour)) yes, travel on such a highway is not cheap, about $ 50 for a section of 400-500 miles, and people choose, either quickly and for money, or calmly on a free alternative highway. Next year, a 1,300-mile section from the European part of Russia to Siberia should be opened. And there are plans to build such a highway across the country, 8,000 miles long

As I said... but go on, do what you do.

Holy cow!! That sounds awesome! I may have to visit when I can drive from one side to the other on a paved, high speed, road. Pretty neat stuff. I like progressive thinking, although I hate toll roads. But, I understand that 8000 miles of road isn't cheap to build or maintain.

What kind of fuel economy do you get driving like Mario Andretti? Also, what is your fuel cost in Russia?

Of course come))) we have a huge number of interesting places)) here is a photo, for example, in the Ural Mountains. On the border between Europe and Asia)) fuel consumption in the mode of 100-100 mph turns out to be about 11.5-12 mpg, and gasoline is similar to the American 91, in our country it costs about $ 2.7 per gallon

 

[the 18th letter]

I would imagine fuel stations are decently frequent on those roads. Sounds great, I wouldnt mind cruising at that pace with hardly any traffic around.

LOL, we have those roads here. We call them 'Texas'.

If you plan to keep your vehicle for a long time I would replace all the ATF before 20,000 miles. GM may set spec's but the bean counters are in charge of procurement and they will always purchase the cheapest that just meets the spec's. There are much better ATF out there then what GM sells. I would never put any lube with the GM logo on the bottle in my vehicle.

LubeGard's version of Dexron6, and Mobil1's versions of Dexron HP and Dexron ULV,
are all made with Group IV polyalphaolefin base stocks.

Unfortunately, there are not as many gas stations as we would like, but they are developing, while you have to plan, and just in case, take 1 canister of 20 liters with you) just last year during the New Year holidays, it came in handy, when the flow of cars on this highway was so large that the queue was 3-4 kilometers. But based on the experience of other toll roads, all this will change over time. Again, no one prevents you from leaving the toll road, driving 10 km to a small town, eating, refueling and returning to the toll highway to continue your journey.
For example, here is my way, with an average speed of 155 km/h for 645 kilometers

We have a 10-speed Ford gearbox. We pour Motorcraft liquid into it

Well technically you have a 10L80, which is the GM variant of the 10 speed that was developed as in a joint-venture between GM and Ford. The Ford variant is the designated as the 10R80.

I would assume the difference between AC Delco Dexron ULV and Motorcraft Mercon ULV is nil, since they are more or less the same transmission.

Is there a general consensus on when it’s best to change transmission fluid and filter under normal driving conditions in the ‘21+ Tahoes?

Service manual from Chevy is at a high mileage if I recall correctly, north of 100k. I have an indy mechanic suggesting to I do it now at 60k given issues he’s seen in the past with Tahoe transmissions and metal shavings…not sure how much of that is based on experience with the newest generation. I don’t think the guy is trying to convince me to spend more money just for the heck of it, but id feel better about making a decision with the collective unbiased opinions of you folks here!

Thanks!!

I have changed my trans fluid at every 25k. I have the 6L80 but its heavily abused. So far no metal in the fluid. I'm at 107K and the 6 speeds are NOT known for longevity under heavy abuse. So either the fluid changes are actually working or I got really really lucky (highly unlikely)

 

[Gearz]

I would at the very least do a fluid exchange at about 80K if you don't tow and if you do 50K. To drop the pan an replace the filter 120K. In the early two thousands the dealer I was working for was doing 50K flush and so on like I said above. It all depends on your driving habits, climate and if you tow or is the truck equipped for towing like a heavy duty trailering package. There is not one answer for every situation. The owner's manual is a guide!
