COOPERATION BETWEEN 5AT AND DRIVE-BY-WIRE
With the new Drive-by-Wire Throttle System, the function of the engine and transmission can be closely choreographed for faster, smoother shifting. Upshifts from first to second gear, and from second to third gear, are more than 0.3 seconds quicker-a 33 percent or better improvement. In manual mode, driver-commanded downshifts are also more than 0.3 second quicker. Meanwhile, the peak g-or "shift shock"-has been reduced significantly during upshifts and downshifts


but does it explode and as we get more repalcements will this be the tranny we get?

.3 tenths if i remember the CL-S' is .9 so now it's .6 thats good

 

Drive by wire is supposed to help to eliminate the problems with the current CL/TL trannies. If you read through the tranny findings thread in the tranny forum I recall the author of the post mentioning that drive by wire will fix alot of the problems. I doubt drive by wire can be implemented onto our cars though, the gas is already "hard wired" to the car, you'd have to do some serious work to retrofit drive by wire.

 

Drive by wire didn't do anything super special for the 2k2+ maximas.. i feel that drive-by-wire is actually hindering my 2k3 maxima (auto) from its peak performance

 

Somebody find out if this auto has a tranny cooler,, ????

 

my hope is that they will make the auto TL have the ability for the driver to control the 2 - 1 shifting and be able to control 1st gear. as the current TL/CL sportshift doesnt allow control over 1st gear

 

Acura's ATs have lost all credibility with me until proven to work.

 

Thats ok because I plan on getting the 6-speed and learn how to drive stick! Come on AWD!

 

Hey Jimcol,
It's a good possibility b/c the TSX allows you to control the 2-1 shift. I was surprised when I went for a test drive.

 

the RSX does the same.

 

no you can not control first-second shift.. it is the same as the current 5AT

 

in the RSX you can, dunno about the TSX.

 

thats gay as hell.

i wonder if this is the same shitty tranny they already have? youd THINK that honda would go back to the drawing board and totally do a brand new transmission after the disaster they currently have. hopefully so. otherwise the TL will have a very dark cloud following it around.

 

Yeah but it has the same 4th gear ratio as our car.

 

On the Type S autos they were cutting timing in the ECU during shifts to keep power down and help with wear and tear. Hopefully the drive by wire will do a better job managing the tranny.

 

WTF: That really sucks!!! I don't understand why Acura feels we need 2 overdrive gears. It just doesn't make sense to me. :shakehd:

 

did any of you guys bother checking into why the trannies falining? i know some did but very few. anyways, i highly doubt drive by wire will make much of a difference. but it will allow for the comp. to pay better attention to the tranny. the reason for failure is not poor design. it is because of a part that was went cheap on. the only reason they changed the ecu is to furthur prevent the tranny from overheating.
i think honda didnt spend enough time on its tranny at first, but the revised one had some decent attention

 

DBW is considered a countermeasure to help prevent the tranny from overheating by reducing or eliminating throttle at shift points. If the problem is overheating, and DBW by controlling the throttle reduces heat to the level where it won't overheat then I say thats a solution ... I'm sure Honda put some more thought into the tranny this time, ensuring that the quality control on the clutch packs did not go unnoticed as it did with the earlier CL Type S's.

Along with this, as long as Honda redesigned the tranny to allow for more ATF to enter the clutch packs (to levels where it would not overheat, the problem that owners were experiencing with the CL/TLs should be reduced greatly.

 

good point. seems like you understand this subject than most. the atf overheating was a problem in the past, but the revised tranny definately took care of that. beyond that, i think you are right that they will pay more attention to the quality of the clutch packs. they definately do not want to spend a bunch of money on the new models too.
