How did your car, truck or SUV transmission make out with this Wonder Lake winter?

How did your car, truck or SUV transmission make out with the Wonder Lake winter that, hopefully, is past in fact, not just in name? Why would we ask such a question? After all, in terms of your transmission, what’s the difference between summer and winter?

Not surprisingly, the biggest difference is the cold we experience here in Wonder Lake during the winter. It gets cold – darn cold – during the winter months. And those chilly temperatures do have an effect on your transmission. In fact, the cold specifically changes things in two ways that make life difficult within your transmission during those cold winter months.

Transmission fluid thickens: They call it a change in viscosity. When the transmission fluid is thicker, it does not flow as readily through the passageways designed to carry it to needed areas of the transmission. In other words, the transmission may not receive the intended degree of lubrication.
Parts contract: When parts are cold, they contract. This creates additional space between parts. Those parts, which include a lot of gears, are designed to mesh with certain tolerances. When the tolerances change, the parts don’t mesh correctly, and increased wear and tear is likely. Contraction of parts can also result in leaks.

Some of the problem winter poses for your transmission is external – it relates to factors that are outside of the transmission, though they cause a problem for parts inside the transmission. For instance:

Slippery conditions: If you’ve ever found your drive wheel on an icy surface and then felt the jarring reaction when the tire hits dry pavement, you have an idea of how the changing conditions of surfaces can effect your transmission. That sudden change in traction can be like hitting your transmission parts with a hammer.
Stuck conditions: Hopefully you haven’t been stuck in snow and/or mud in a long time. But you probably remember what it was like when you were. The tires just spun and spun but you didn’t go anywhere. It’s likely that you tried rocking the car, truck or SUV to break free. You might even have taken to shifting from Drive to Reverse rapidly to increase the level that you were rocking the vehicle. These kinds of actions are hard on a transmission.

The Wonder Lake winter of 2021-22 is passing into the record books, good, bad or just normal. But, whether it’s ready to go or plans to stick around for a little while yet, it has posed challenges for your car, truck or SUV and the transmission that you depend on to keep you moving.

This is a good time of year to have your transmission checked out, along with other parts of the vehicle, to make sure that they all survived winter in good condition.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

Get out to McHenry Music Festival for a good time and music near to home

Some folks here in McHenry will load up the car and head out to Red Rock Amphitheater near Denver to see a show. Some will go to the MSG Sphere near Las Vegas. Some will go to the Bonaroo Festival Concert to see a show. That’s quite a bit of driving and you’d better make sure your vehicle is up to the trip. What happens, however, if something goes wrong – if your vehicle breaks down while driving there or back? What happens if the show is canceled, as happened this year with the Bonaroo Festival? We’re talking about some serious inconvenience, aren’t we? Wherever you go, whether your driving to Colorado, Nevada, Tennessee or anywhere else in this continent, you want to perform your due diligence and make sure the vehicle is up for the trip before you go. And it doesn’t really matter if you’re driving somewhere to see some live music or for any other purpose. A breakdown can be costly and may put you at the mercy of weather conditions or nefarious characters that come across you while y...
