Fluid question

[snowman44]

I have a 2008 Chevrolet Silverado with 66k. I plan on keeping truck for another year to year and a half. DO you think it is worth to have transmission flushed or just drive it. Truck is used sparingly in summer as I ride my motorcycle. I am just anal about my vehicles and looking for advice. Thanks for help in advance.

Drop pan, replace filter, top off fluid and drive it. I wouldnt do flush.

This is what I would do.

Owners manual for my '08 recommends changing the fliter and fluid at 100k miles in normal service. 50k in severe service. Dexron VI has got some pretty good properties.

more important question, what motorcycle do you ride

If you are only keeping it a year to year and a hald, I wouldn't bother. It won't be at or above 100k miles if driven with the same frequency as you have historically.

Regardless of what the owners manual says, I would NEVER go 100,000 miles in normal service before changing the plugs or fluids. 50,000 max. Give yourself some peace of mind. Drop n Fill. Do the plugs, coolant, power steering fluid, front and rear diff, and transfer case while your at it. Why do you only plan on keeping it for only another year to year and a half? Just curious.

May I ask why? I routinely checked my fluids and plugs which easily made it 100k miles, with exception of transmission. I had the filter changes at 50k due to towing and it still looked red and unburnt. My plugs were changed at 107k miles and were just starting to look due. Did you have a bad experience or just personal preference? Just curious as well.

Fluid wears down over time, and absorbs moisture. Keep in mind if you drive in stop/go traffic, or if it gets below freezing, you're basically in the "severe service" category.

 

At the end of the day, the tranny is just a mere $7k, so a $50 oil change is cheap insurance.

Sure, because the guys who design, build and test these trucks have no freaking idea what they're talking about. Just ignore their recommendations. A good friend of mine works for GM, in the powertrain test lab. It's his job to test (and abuse) transmissions. He's smart. He says do what the manual says. I'll take his advice.

 

Dexron VI is light years ahead of Dexron III in terms of performance and retention of properties. Ditto with platinum plugs vs traditional plugs.

 

And GM says DexCool is good for 150,000 miles.

 

Oh, and BTW, I own two Chevy trucks. The '01 has 193k miles with the original engine and transmission, and the '08 has 130k miles. Both run flawlessly, have been driven very hard and abused, and both run like new.

Thanks for input. My bike is a 2014 harley Davidson Nightrod in black denim

****You go right ahead and do that. I'll take the advice of those who work on these things long after the boys at corporate lose interest and are too busy working on the next newest thing.***

That doesn't mean that fluid breakdown and acidity issues won't exist. This goes for ALL coolants out there not just Dexron. As for the plugs.. ever hear of the issue with the Ford plugs being melted into the block come time for their 100,000 factory reccomended replacement? Guess what, it has been known to happen on GM and other brands who say 100,000 miles.***

 

And GM says DexCool is good for 150,000 miles. ***Of course they do. Why do you think that is? I bet you won't be able to answer that one correctly. Here is a hint though.. by the time most normal driving owners hit 150,000 miles the truck will be 10+ years old. What happens as things age? They break down. Rubber deteriorates, additives in the fluids no longer function, acidity levels in the coolant build up, and then you start wondering why your water pump is going out at 100,000 miles or why you have cooler or heatercore issues at 100,000 miles well before that so called 150,000 mile change out requirement for the DexCool, or any other brand of high millage coolant.***

Both run flawlessly, have been driven very hard and abused, and both run like new. ***That's great! I bet you can get even longer life out of them if you performed preventative maintenance. It's like those who have the Toyotas and Hondas will say.. "I have 200,000 miles on my car and I have never had to do a thing to it." And I say.. "So you did not change the plugs or the coolant, or the oil or the power steering fluid or have it inspected?" "Nope." And then when they do change the plugs, they wonder why it drives even better now. Or when they do change the coolant, they wonder why the fluid looks so bad and then why they have leaks all over the place once they do get around to doing the maintenance they should have done long ago. The key term here is PREVENTATIVE MAINTENANCE. Either you believe in it or you don't. Those who do believe in it, thend to have less troublesome vehicles. That has been proven. Not trying to start a pissing match here, but there is a reason I strongly emphasize the PM stuff. I like things to last a long time. And given the bad shotty workmanship/quality control and other issues GM has been experiencing as of late, I don't think I'll believe anything that comes from anyone in the company for quite a long time. They have a lot of damage control to do and a lot of work to do to become a company of integrity and to earn back the trust of once loyal and faithful owners. I do think they can do it. The question becomes how badly do they want to do it, and how much money do they have to do it, and how are they going to implement it? Time will tell. ***
