Find out how to test your automotive’s transmission fluid

Most drivers know that they should test their automotive’s engine oil and prime it off as wanted frequently, however most drivers additionally neglect about their transmission fluid. Identical to an engine, a guide or automated transmission depends on oil to remain lubricated, and working it dry can have disastrous (and disastrously costly) penalties. Comply with our information to learn to test the transmission fluid in your automotive.

We will not say that we blame the parents who do not commonly test their transmission fluid. In lots of vehicles, it is a comparatively tough job except you are a factory-trained technician. Some late-model vehicles are fitted with a sealed dipstick tube, and the dipstick is a manufacturing unit device that you just doubtless do not have laying round your storage. You should buy one, both from a vendor or from different distributors, however realistically there are instances the place the best and most reasonably priced strategy to test how a lot fluid is in your transmission is to take your automotive to the store. There are additionally some vehicles with an digital dipstick, so the extent seems on the dashboard, and others whose transmission is ostensibly sealed for all times.

Automobiles with a dipstick

In different vehicles, it is much more straight-forward: some transmissions are geared up with a dipstick much like the one you utilize to test your engine oil degree. If that is your case, or if you happen to’ve invested in a dipstick, checking the transmission fluid degree ought to solely take a couple of minutes.

First, discover the dipstick. It ought to look so much just like the engine oil’s dipstick, nevertheless it’s positioned both additional again within the engine bay or off to at least one aspect, relying on whether or not the engine is mounted longitudinally or transversely. Discovered it? Good! Park your automotive on a flat floor (leaving it on a hill provides you with a false studying), shift the transmission into park or impartial (do not forget to set the parking brake if you choose impartial), and let it idle till the engine warms up. When it is heat, fastidiously pull out the dipstick, wipe off the fluid with a clear rag or a clear towel, and pop it again into the tube. Slowly take it out once more and you will have a studying; there must be excessive and low marks on the underside a part of it.

If the extent is low, you may want a funnel and the proper kind of transmission fluid to prime it up (bear in mind to show the engine off first). The fluid usually goes immediately into the dipstick tube. And, identical to once you’re topping up the engine oil, begin slowly and commonly test the extent by following the aforementioned process if you do not know how precisely how a lot fluid it’s best to add to succeed in the “excessive” mark.

Earlier than wiping the dipstick clear and calling it a day, take a minute to take a look at the fluid. It must be dark-ish purple or light-ish brown. If it is darkish brown or black, it’s best to plan on altering it and its filter within the close to future. If it smells burnt, there’s doubtless a difficulty with the transmission.

Automobiles with out a dipstick

Broadly talking, the dipstick methodology largely applies to vehicles geared up with an automated transmission. And, broadly talking, vehicles fitted with a guide transmission would not have a dipstick, although there are some exceptions to each of those guidelines. When you’ve obtained a guide transmission, checking the fluid degree will doubtless require significantly extra effort and time than merely pulling out a dipstick and wiping it clear.

It isn’t not possible, although. First, park your automotive on flat floor and jack up the entrance and rear ends. Ensure that they’re degree; you do not wish to have the entrance finish larger than the again finish (or vice versa). Crawl beneath it, find the transmission, and discover the filler plug. It is bolted into the casing on the aspect of the transmission. Do not confuse it with the drain plug, which can also be bolted into the casing however positioned decrease.

Unscrew the plug (a wrench often does the job, although some vehicles require a particular device) and needless to say fluid could leak out, so we suggest having a rag helpful and never laying immediately beneath the transmission along with your mouth open. With the plug off, peek into the transmission’s guts; the fluid degree must be proper on the backside of the filler plug’s gap. If you cannot see it, use a finger to inform the place it is sitting.

You are good to go if the fluid degree is the place it must be; exchange the plug’s washer if wanted, tighten the plug, and decrease the automotive. If the extent is low you may have to prime it up, which might get messy. You’ll be able to’t pour fluid immediately into the transmission, so essentially the most straight-forward manner is to make use of a pump (ideally a hand-operated one) so as to add fluid from a container till the extent reaches the underside of the filler plug’s gap.
