Source here- Shifting into Sixth Gear! These companies formulate oils down to a price, rather than formulating them to be the best product they can be. No one else even comes close to this amount of experience with synthetic lubricants. I just know when you pay 56,000 dollars for a vehicle you expect to have zero trouble out of it. Case in point, 3,000 miles or 3 month oil change. I know some of the corvettes have the 6. This is very annoying and could potentially be dangerous.
This last trip they replaced the entire transmission and the problem still occurs. If you accelerate slowly from a red light it takes 3 to 5 seconds for it to shift gears it just shakes and wobbles until that shift takes place. Any good semi or full synthetic with meet dexos standereds. Is that Dexos certified yet? But you can also rotate the air in your tires every 500 miles and buy new tires every 20,000 miles too. Have put synthetic in every fill plug on the truck. I hope i am ok Should i go and drain some oil? You are working it harder, probably idling more, etc.
Mike aka Z15 has some good info about Amsoil, he is a distributor. Not sure why the accelerator pedal has so much travel when the transmission only uses the top half. I can confirm that by saying that i used all the 6 quarts empty bottles and started pouring old oil into them to measure exactly how oil. Yeah, even changing it yourself with a synthetic like M1, it was a bit chunk of change. I have had my truck for over 2 years and it still shifts poorly. If it isn't printed on the oil cap, check your owners manual for the exact type before adding new oil. Update from Sep 22, 2016 : I am now at 23,000 miles, after the fourth and final trip.
You led us to believe it was your Denali and that is what I assumed. And that's a Canadian bargain for y'all down south. I filled all 8 quarts bottle and there was still some oil left to fill another 2 bottles and dont frorget the spilled oil and oil in the filter etc The dip stick is definately showing oil more than marked indicator but i have a doubt the dip stick might be installed incorrectly. But pick a really good oil, and then stick with the brand you choose. Vehicle back at dealer today and now I'm told there's a bulletin and there's no fixing problem, it's a design problem. What makes them dangerous is that they have some sort of initial credibility.
I've taken it back to the dealer at least 5-6 times, I've been told it needed to be reprogrammed, that it needs to get used to the way I drive, and poor gas. Gm states these transmission problems are considered nomal operations. It can get down to -40F here. All of these fluids are extremely harmful to your eyes and skin so it is important to protect yourself. Tech wrote chattering during road test. For instance, say you start your car on a 20° F day and take a two-mile trip while towing a heavy trailer. Drove home same problems and now have exhaust leak.
Other oil companies, however, are beholden to shareholders, and one could speculate that their incentive is to maximize profit. When I accelerate there is a hesitation for a second or 2. It felt like the torque converter was banging back and forth. Y'all can now jump on the ridicule wagon cause I always change oil 3-5 K. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures.
So if they have known about this for quite a few years. The engine might have come fitted with a larger oil pan? Floor it from a stop and shifting gears it wobbles and either jerks into gear or slips horribly into gear. What makes them dangerous is that they have some sort of initial credibility. I stood right by the window and made sure my oil was changed properly, so no issues there, and yes they put in 6 quarts. Since the beginning a few weeks after I bought the truck I noticed a hard shift on the transmission.
I got a price to trade it in but it was going to cost me a great deal more and I honestly don't see why I should have to spend more to get a vehicle that is mechanically sound when my truck only has 15,000 miles on it. Of course after this the truck still shifts hard. I love my truck, the 6. I'm shuttering at the though of how much that is going to cost. The problem was not fixed. So Gm has known about this and they did not disclose this to us so filed for lemon law this week.
That should last me about another 1. Hi Guys Just Joined so hello. The minute you accelerate to try and compensate, the transmission clunks and the truck lurches forward. I'm shuttering at the though of how much that is going to cost. On a side note your dealer will not let you upgrade the free oil change to a full synthetic oil change. They did however contacted the dealer and offered tech support which produced no results as I still have the problem.
