The Basic Parts of an Automatic Transmission

[EricTheCarGuy]

I’ve been wanting to make this video for some time. I’m glad I finally got the chance to bring it to you. I’ll make future videos based on the questions I get about this series so feel free to ask away.

I also enjoyed this video. I have not had the courage to dive into a transmission rebuild. Everytime I pull off the pan I am terrified when I see the “brain”. It must take a real pro to rebuild one successfully. I’ll stick with ordering mine from Jasper.

Can’t wait for part 2 🙂

I almost forgot to post part 2.

How bout this one for your Eric….

I have a 1998 Acura CL 3.0 B7ZA automatic transmission that flares on the 1-2 shift when cold and bangs on the 2-1 shift randomly..i.e. – doesn’t have to do with temperature on the 2-1 bang.

What would your best guess be? Internal/mechanical problem? Electronic control problem (solenoid, CPC Valve, clutch pressure switch) ? Or hydraulic/pressure problem…. I guess the internal/hydraulic are kind of the same I guess…

How many miles on your transmission?

If I had to guess, you might need a band adjustment.

170,000. Honda’s use Non-Planetary transmission’s and do not have ‘Bands’.

Hey Eric: I was wondering if you plan to make an educational video for sale for us techs who don’t understand automatics? Just saw the TC video and it is helpful to see the ‘real deal’ and not just read about it. Thanks for some great info on the AT.

So much information

Thanks for the video Erick, glad to have you around. I was thinking about some parts that you mention in the video. The flex plate, clutch, and torque converter, Do any of these parts need to be change as an maintenance routine? The reason why I ask is because I notice that every time I am sitting in idle waiting for the light to turn green, I notice a rough idle or some rough shake while is in the Drive gear. Its not that bad but it is noticeable. But if I set the gear to neutral, the rough idle is gone. Any idea what that might be?
BTW its a 2005 Nissan Sentra 1.8L

I really enjoyed these videos. On one hand I appreciate the complexity of an automatic transmission. On the other hand I think these did give me the gist of how they work. I am looking forward to the torque converter video especially how they lock up at the right time.

I like the mention of the differential and the possibility of a video on one at some time. I can appreciate that can be a rich topic too. With that in mind I have hope that a video can be made so the mention of the various locking ones can be mentioned and even cover which ones are good and not so good. I hope to one day have lots of extra change in my pocket and rig up a four wheel drive with some sort of locking diffs in both axles. At this point I still don’t know what kind(s) I would want to have installed.

In summary it looks like there are lots of automobile topics out out there to get to have future videos on.

PS to my above comment. Could we have a dissection video on a standard transmission too at some time?
