Orphaned article[edit]
I added a link to this article in Trucking industry in the United States, but I will leave the orphaned notice up. Honestly I'm not sure how many other articles could link to this page as the subject is rather specific. --ErgoSum88 (talk) 18:44, 21 February 2009 (UTC)
Synchronizers[edit]
The article talks about synchronizers. Most of the larger trucks, especially Class 8, in the U.S. don't use synchronized transmissions. In fact, many if not most truckers don't use the clutch when shifting, as the helical ground gears are fairly easy to mesh when proper RPMs are reached, and most experienced truckers can synchronize gears manually.Caisson 06 (talk) 03:23, 15 March 2009 (UTC)
- You are correct. However, this is not my area of expertise so I'm not sure how to fix it. --ErgoSum88 (talk) 04:46, 15 March 2009 (UTC)
- There is life outside the U.S. Synchronized manual transmissions are common in heavy trucks throughout Europe. — Preceding unsigned comment added by 193.199.100.4 (talk) 19:59, 9 September 2011 (UTC)
Troll physics[edit]
"When done properly, progressive shifting often results in quicker acceleration because diesel engines produce the most torque in lower rpm ranges." Yeah, right. That is not directly related to torque. — Preceding unsigned comment added by 193.199.100.4 (talk) 20:00, 9 September 2011 (UTC)
Alternative definition for progressive shifting[edit]
"Progressive shifting" is a technique used to conserve fuel, and it is meant to work by shifting when the engine is at high torque so that little fuel is wasted to overcome the engine's inertia and to optimize the engine's performance. According to Roadranger, a company that produces truck parts and an associate of the Eaton company, whose brand is often seen on transmissions in modern trucks, progressive shifting is done at various RPMs (all depending on the specific transmission) until 6th gear and 22 MPH is reached, at which gear and above up-shifting is done at, for example, 1700 RPM, that is, just below the maximum RPM that is set (governed).
