I have a 2019 Chevy Silverado. At somewhere near 30,000 miles, my proprietor's manual says I should change the best transmission fluid for Allison 1000 The Chevy Silverado business says that they just changed a part of the fluid for reasons unknown.

That looks bad to me. A halfway change resembles doing a half-oil change on your motor. I got some information about the shops that have a machine that guides into the Allison transmission line and siphons all the old fluid out and new fluid in. The vendor said that was not a smart thought since garbage in the Allison transmission could obstruct the lines.

That much garbage after 30,000 miles? I will likely go to a shop that utilizes the "full change" technique, yet I am interested in what you think.

All things considered, for most Allison transmission fluid changes, the machine works extraordinarily. You connect it to the Allison transmission cooler lines - one going in and one going out - you add the right measure of new fluid to the machine's supply, then, at that point, you turn over the motor, and the machine takes out all the old fluid and replaces all of it with new fluid.

What's more, as a rule, you're correct, Allan. It's smarter to change all of the fluid than a portion of the fluid.

Envision, we were discussing your espresso mug at work. If you thought that it was half brimming with cold espresso on a Monday morning, would you simply add a large portion of some new espresso? Or, then again, would you spill it out and add all new fluid?

However - and bizarrely - on this vehicle, I would utilize the two techniques. Here's the reason: Chevy Silverado is exceptional in that they suggest an Allison transmission fluid change at just 30,000 miles. They likewise suggest that at every fluid change, you clear off a magnet that is connected to the channel plug. What's more, that is likely the main piece of this necessary upkeep.

The magnet at the lower part of the Allison transmission gathers every one of the metal shavings that are worn off the cogwheels, grasps, and orientation. The magnet grabs hold of those shavings and keep them from flowing, harming other inside parts or obstructing the little interior fluid sections in the valve body.

What's more, here's the issue. Assuming you simply utilize the machine or use it first, you could compel those shavings off of the magnet and recycle them, either obstructing those entries or leaving the shavings suspended in the fluid again, where they can stop things later.

So in a perfect world, you'd utilize the two strategies. Channel the Allison transmission by eliminating the channel fitting and cleaning the magnet-like they tell you to, and afterward, connect the machine to change the entirety of the fluid.

Then again, in case I was simply going to utilize one technique or the other, I'd likely settle on the drainplug on this vehicle.

Chevy Silverado had some Allison transmission issues, and I'm speculating that the magnet - and the cleaning of the magnet - is a vital piece of their answer. So essentially, get the magnet cleaned. What's more, in case you're feeling picky, utilize the machine after that.
