I’ve been working on two additional articles. One is another, shorter technical piece as a followup to the previous articles. The other leading possibility is the first-generation (1971–1977 A20/A35) Toyota Celica.
To that end, I will need to gather more photos of the Celica as well as its cousin, the A10/A15/A30 Toyota Carina, the rival Mitsubishi Colt GTO and first-generation Nissan Silvia (a.k.a. Datsun 200SX), and ideally one or two of the early Mazda Savanna (RX-3) coupe.
If you’d like to help with pictures, please let me know via the Contact Form. Thanks!
As you probably all know, I’ve been working for months on an extensive revamp of the second part of my 2010 article on GM’s early automatics, covering Dynaflow, Powerglide, their successors (including Twin Turbine Dynaflow, Turboglide, and Dual-Path Turbine Drive), and the later generations of Hydra-Matic. That revamp is now done.
The article has been almost completely rewritten, adding a lot of new information (more than doubling its length in the process) and incorporating a lot of corrections. Unlike the previous version, I’ve made a concerted effort to explain the mechanics of each of the 14 transmissions discussed.
You can read it here. If you somehow missed the revamped Part 1, covering the origins of the first Hydra-Matic, click here.
You may be wondering, “When is Ate Up With Motor going to stop messing around and provide some actual new content?” This is a fine question and you’ll find an answer of sorts below.

For various reasons, there has been a dearth of new content in recent months, although I spent a while making a lot of housekeeping changes to older articles, fixing factual errors, and the like, and I am still working on the update of the Dynaflow/later Hydra-Matic article that will likely be the next major article. (As with the first part of the Hydra-Matic article, I have been going through a lot of technical documents and patent literature to get the workings of these things straight, which is complicated by there being so many different transmissions.)
I realize that it is frustrating for regular readers, but I recognize that I get a lot of “long-tail” traffic of people coming to articles months or years after the fact, and I’ve had the unhappy experience before of seeing other people innocently repeat factual errors I’ve made, which is part of why I get caught up in trying to get it right. I know this flies in the face of the “hit post and move on” philosophy of most web content, however, so I appreciate your patience, however strained!
Over the next few weeks, I’m going to be experimenting with some new anti-spam tactics. My existing solution, which had been working pretty well, now has some serious shortcomings following the most recent update to the content management system, so I’m going to need to try something different. (I get hundreds of obvious spam comments every day and having my email inbox flooded with spam comment notifications every few minutes is not fun!)
Since I’m going to have to resort to a certain amount of trial and error, there may be some oddities with commenting or the forms. If you have problems or encounter something strange when leaving a comment or submitting a form, please let me know. I’m very concerned that spam prevention not present an irritation or accessibility problem for my sapient readers.
ETA: I want to draw a clear distinction here between hotlinking images and simply reusing them in some other manner, stipulations for which are discussed in the Reprint/Reuse Policy. If, for example, an image is in the public domain in your jurisdiction, you’re certainly welcome to copy the image and reuse it elsewhere on the web — just don’t expect me to host it for you (which is what hotlinking entails) without asking me first!
I discovered earlier that in the recent update of the Hydra-Matic article, I had made an embarrassing error in the description of the 1937–1939 Automatic Safety Transmission. The error is now corrected, but if you want a more detailed explanation, see below.

I have spent a lot of time over the past few weeks undertaking an extensive update of the 2010 article on the original GM Hydra-Matic transmission. The goal was to clear up various errors and points of confusion as well as trying to do a better job of explaining the operating principles of both Hydra-Matic and its precursor, the Automatic Safety Transmission.
This endeavor, which has reminded me why I’m neither a mechanic nor an engineer, was actually a good deal more work than the original draft. However, since people continue to read and refer to this article, I felt it was appropriate to try to sort out its inaccuracies and confusing points.
You can read the full article here.

I’ve updated the site’s Reprint/Reuse Policy (which is now linked in the Administrative Pages menu on the right for ease of reference) and I encourage everyone to read it. The policy is not significantly different than it has been, but I’ve reformatted it to make it easier to read and to clarify a few points.
As with all of the site’s policies, I’ve tried very hard to balance what I reasonably need to do to protect myself and my rights with an appropriate respect for common sense and the principles of fair use. If you have any questions, please feel free to contact me.
ETA (Jan. 13, 2016): I have made a further update to the policy — including reorganizing and reformatting parts of it — in the interests of clarity, avoiding inadvertent contradictions, and trying to balance a bunch of conflicting priorities. I encourage you to read the updated policy if you’re interested in excerpting an article, reusing photos, or anything like that, and to let me know if you have questions or concerns. My intent is not to be scary or unduly restrictive while covering myself and the people who are kind enough to let me use their photos and other material.
The other day, I got an email from author Michael Lamm with some exciting news: one of my favorite automotive books — and one of the most important resources on U.S. automotive styling — is back in print.
