As of the end of March '08, after mentioning the Automatic Safety Transmission, this page says "The results were not quite what GM Research had in mind", which could mean anything. Obviously, it should say something like "sales were poor" or "it was very popular", but I don't know which. This page says it sold very well (at an artificially low price); this page says it didn't. I don't know which, if either, is correct. Groyolo ( talk) 03:41, 31 March 2009 (UTC)
I just watched a commercial for the Sierra and I'm pretty sure it said it has a "Hydramatic transmission." Is this name still in use? The article seems to suggest it is not.

In the "Design" section, it says
"Upon shifting to third, the forward gear assembly went back into reduction and the rear gear assembly locked. Due to the manner in which the rear gear assembly was arranged, the coupling went from handling 100 percent of the engine torque to about 40 percent, with the balance being handled solely by the gear train."
and
"The shift from third to fourth gear locked the forward gear assembly, producing 1.00:1 transmission. The fluid coupling now only handled about 25 percent of the engine torque, reducing slippage to a negligible amount."
I believe those statements are incorrect and that the power division was 50% mechanical gears and 50% fluid coupling in both third and fourth gears. For explanation, see Dual Range Hydramatic Power Flow

the real question should be is why the stuart wont go into reverse, with out grinding a pound of scrap metal. and how did thay solve the problem? — Preceding unsigned comment added by 65.101.219.154 ( talk) 16:32, 16 February 2014 (UTC)
For a few years before and after 1960 Vauxhalls and Holdens were fitted with Hydramatic gearboxes. Eddaido ( talk) 09:32, 26 September 2015 (UTC)
In the statement, ″During the 1930s, automakers sought to reduce or eliminate the need to shift gears. At the time, synchronized gear shifting was still a novelty (and confined to higher gears in most cases), and shifting a manual gearbox required more effort than most drivers cared to exert", the 'automakers' comment holds true only for American manufacturers. The large growth in the popularity of automatic transmission occurred in the US market but elsewhere, for a variety of reasons well documented in a study by Edmunds [1], more than 80% of cars sold in Europe in 2020 have a manual transmission, compared to just 3% in the USA. So, 'most drivers' is inaccurate. Outside America, non-manual transmissions are usually found solely in prestige models aimed at higher earners. Similar considerations pertain in much of Asia and Africa. I appreciate the Hydramatic is principally an American technology but much of the article's content and style are written in American English and biased towards the situation in the USA.
