can i get detailed gear ratio calculation of 725 9g tronic ? please , i been searching this for longer period Premanandh30 (talk) 05:20, 2 September 2022 (UTC)

Hi premanandh304,

every details you need you may find in the chart: all formulas are mentioned so you can enter them right away for instance into an excel-spreadsheet and then "play" with the gearsets. R1 means ring gear gearset 1, S1 means sun gear gearset 1 and so on. In total there are 4 gearsets. Please note that there are two different versions (with different gearsets 3).

I don't have further information. I just developed the formulas from the well-known Willis-formulas for epicyclic gearing (you can find an entry for here in wikipedia; german: Umlaufgetriebe).

In case of any further questions please let me know.

Cheers Peter Musikgeniesser (talk) 11:37, 23 September 2022 (UTC)

Thanks a lot. I really grateful for this reply . But i am really can't understand how you created the formula for any gear set from Epicyclic gearing . if you help me out it will lot help for my thesis. is there any way i can contact you??? or can you share how you derivate the formula by any means?? Premanandh30 (talk) 04:21, 6 October 2022 (UTC)

Sure. I sent you an e-mail to premanandh304@gmail.com but I never got an answer. So I send you again one to premanandh30@gmail.com. Maybe the 304 was a misspelling. 2003:E4:1F1F:7100:69D9:E5B2:4270:D2E2 (talk) 08:30, 7 October 2022 (UTC)

If you merge one article into another, the merged article must redirect to where you placed the merged content. I have seen two articles where you merged two articles together and then wanted the one that content was merged from, deleted. If you merge any more articles, please redirect the merged-from article to the merged-to article. ~ GB fan 12:57, 23 January 2024 (UTC)

You recently merged two Toyota/Aisin 8-speed transmissions into one article. These are two completely different transmissions wholly unrelated to one another in nearly every way. I was looking for information that used to be in the article about the AW8F35 transmission and could no longer find it. I tried to undo your edit to see if it would separate the articles back into two separate pages, but it didn’t, so I undid the change. These two transmissions should have separate Wiki pages.

If you understand basic information about transmissions, it would be like putting the VW Group’s DSG transmission and Porsche/Audi’s DL501 7-speed dual clutch transmission in one article just because they both have 7-gears. One of the Aisin transmissions is a transaxle designed for front wheel drive vehicles. The other is designed for longitudinal engines like those found in Toyota’s trucks, Lexus models like the older generation LS, IS, GS, etc. If you would please undo your merge I would appreciate it.

Hello TurboChargedChilliPepper,

Thx for your mail. Your theses are untenable.

(1)

I did not merge Aisin-8-speed transmission articles, because there didn't exist more than one. There was only the AW F8F35 article existing. At least I didn't find a second 8-speed article either for Aisin nor for Toyota. Please let me know whether you did. Thank you in advance.

(2)

That old kind of article didn't meet the requirement for an article in an encyclopedia. As Wikipedia isn't a marketing platform I added some information regarding the Aisin and Toyota 8-speed automatic transmissions of the AW F8F35-type, i.e. with the same layout as the AW F8F35. Actually all Aisin and Toyota 8-speed automatic transmissions for passenger cars, starting off 2006 up to date, have the same layout as the AW F8F35, as described in the US patent 8,453,818 as of June 4th, 2013. Please refer to it. Thank you in advance.

(3)

I.e., all transmissions listed in the extended and --again -- never merged article are based on the same algebra and shift element actuation scheme. This is reflected in the large template (with assessment). The key data template on top of the article is for a quick overview.

(4)

As a result there is nothing to do for me. I totally accept, that you first need to familiarize yourself with the topic, especially the layout (architecture) of this 8-speed transmissions with its unique reversed gearset 1. The article, as it stands, could be a good start.

(5)

I only added information. Nothing got lost. If you want to read the article in an old version with much less information and much less accuracy, jump back in its history. I wonder why you didn't but maybe you're not familiar to Wikipedia. Just click on the "view history" at the very top right and go ahead. Take a version from 2023 or how old you like it and go for it.

Conclusio

Thank you again for you mail, but there is nothing to do for me. If you find errors in the article I would be glad you let me know so we can eliminate them. Thank you in advance.

Cheers

You don’t have a correct fundamental understanding of these two different transmissions. They are both 8-speed transmissions but are unrelated in nearly every way besides that. Sharing a couple of basic concepts shared by many automatic transmissions doesn’t make them developed off of one another. Look at a photo of the internals and overall design of the AA 80E transmission and then one of the AWF8 transmission. One is a transaxle and one is a longitudinal transmission. Their layout, output shafts, housings, overall dimensions, torque capacity, and all parts internal are completely different than one another.

it’s just like how a ZF 9HP and a ZF 8HP transmission do not share any parts and as such have separate articles on Wikipedia. You keep trying to say in your article that the transmissions are built on the same “patented design” but that is not correct. Besides sharing the same number of clutches and brakes, the actual design and engineering are wholly unrelated.

The AA80E looks like this: https://i.redd.it/aiduevzlk9531.jpg

and the AWF8 looks like this:

https://cimg4.ibsrv.net/gimg/www.clublexus.com-vbulletin/863x744/transmission_001_ad043b4d95755dd39d79af2e2be658771dc7eded.png

Hopefully seeing these two different photos will help you understand they aren’t related. You added a section saying that the AWF8 was a development of the AA80E which is incorrect. The edits I had made that you then changed again to add incorrect information need to be undone. These transmissions aren’t even in the same Toyota transmission family, the longitudinal AA80E is in the Toyota A transmission family and the AWF8 is in the Toyota U transmission family.

Thank you for your repeated reply. I have replied directly to the Wikipedia article. See there. Thank you in advance. Musikgeniesser (talk) 13:13, 3 November 2024 (UTC)

Going back to this topic… the AWF8 (transverse FWD transmission) and the AA80E (longitudinal RWD transmission) should not have combined. They are not based on a shared patent, nor do they even use the same type of gear sets. They also are for completely different layout engines which in and of itself necessitates separate Wikipedia articles for each transmission.

You can see the difference just by looking at the technical documentation for each:

• AA80E (Longitudinal): Technical papers clearly state its patented design consists of one simple planetary gearset combined with one compound Ravigneaux gearset.

• AWF8 (Transverse): To fit 8 speeds and a differential in a small FWD space, Aisin created an all new, highly compact (and separately patented) gear train. It does not use the same simple planetary gearset + Ravigneaux layout. It is a far more complex, "nested" design to make the transmission as short as possible. While both transmissions may have sprung from the same company, Aisin or Aisin-Warner, the AWF8 is a separate and distinct design engineered specifically for the extreme packaging constraints of a transverse (FWD) application. It is not just an AA80E flipped sideways or reversed. The AA80E uses an additional one way clutch that the AWF8 does not use to create 8 forward speeds. The only thing the two transmissions actually share is the total number of shift elements. The transmission pages were correctly listed as two separate entries on Wikipedia.

The overly detailed technical data that you have added to transmission articles is likely to be removed. See this discussion thread for details. – Jonesey95 (talk) 23:56, 16 January 2026 (UTC)

Don't delete, just collapse!

My fellow Wikipedians,

thank you for your interest and commitment.

Without these tables, the articles would be nothing more than product advertising (in this case for automotive spare parts) and would therefore only be suitable for marketing platforms. Let's be honest: none of these articles, or indeed the entire “WikiProject Automobiles,” would have any place in a traditional encyclopedia.

·

Traditional encyclopedias had up to 300,000, maybe 400,000 keywords. Wikipedia has over 7 million and says itself that it goes beyond traditional encyclopedias. That's why the “WikiProject Automobiles” is justified. But that doesn't mean you can write about anything and everything.

·

For automotive transmissions, it is the explanation of the underlying gearset concept, provided here in the tables, that transforms a mere product advertisement into an article of general interest. Therefore, all of these articles are justified in the first place by such explanations. The fact that a complete explanation is possible at all is therefore a fortunate circumstance. Deleting the tables would turn the articles back into mere product advertising.

·

In order not to unnecessarily hinder the flow of reading, I have set all tables to “collapsible.” I am also setting the two tables on economic efficiency and details to “collapsed” so that those who are less interested do not have to hide them and feel annoyed, but rather, only those who are interested will have to display them in the future.

·

Thank you for your understanding and cooperation.

Cheers

There is consensus at that discussion to remove the technical tables. Thank you for your hard work on them, but they are not appropriate for Wikipedia. If you want the tables to post elsewhere, they will be available in the history of each article. Please do not restore the tables; that will be construed as disruptive editing. – Jonesey95 (talk) 00:10, 2 February 2026 (UTC)

@Jonesey95

I heard from the Wiki project engineering the opposite. Ask 2 docs, you get 3 opinons. Musikgeniesser (talk) 00:40, 2 February 2026 (UTC)

I see no evidence of a discussion at Wikipedia talk:WikiProject Engineering. You have no contributions in the Wikipedia talk space aside from the discussion linked above. Please link to this other discussion. – Jonesey95 (talk) 00:51, 2 February 2026 (UTC)
