Go mash the pedal in drive then do it in manumatic mode. Manumatic mode was faster in the 1/4 as well..

Yup, it will get close to redline but never at it.

In MM you can bounce off the rev limiter.

I've floored it in D mode and it never once went to redline. I believe it shifted at 6200-6400(?), but I never redlined it either. My question to you guys is if you were to floor it in MM at 3rd gear would it not shift to 4th? Would it just bounce off the limiter for some time? I know in some cars after a short amount of time it would just switch regardless. I haven't tried it yet because I don't like to beat on my car like that. Maybe someone crazy enough on here tried it already lol.

It certainly does hit redline and does not shift by itself

That's when it's most useful, it allows you to launch in the right gear, after that, I will usually switch it back to auto before the gear shift.
you're excused.

daveb disagreed with me and i'm fine with it. it's an internet forum so relax. folks on car forums always seem to get worked up over nothing.

If I'm right our shift point should be at around 62000 rpms, not redline. That is when our engine makes optimal power and anytime after that point the engine actually loses power.

I drive in manual mode everytime I drive the car, regardless of what people say, it does give you control because lets say if I'm cruising in a neighborhood going 25mph, my car likes to hold 2nd gear at around 2000 rpms but if i go to manual mode and shift it up it'll be around 12000 rpms...gas saver?

It does actually give you control for sure because wether or not it's like a manual, leaving it in D it'll never give you the gear you want.

By the way, I'm not sure about sedans (since I drive a coupe) but as long as you have it in MM to upshift, you're fine. If you're downshifting to every light I'm pretty sure it'll hurt your tranny. You're better off just braking and letting the ECU downshift for you. So really you only spend 98% of your time just upshifting if you use MM daily.

I think the coupe and sedan are exactly the same in that regard. If you have an 05-up(?) with rev-matching I think down-shifting's a bit easier on the trans. Even so, I will downshift at sub-2500 rpm for a bit of engine braking (and exhaust burble, haha!). Wish I had the paddles and grounding gear for quicker shifts, maybe I'll invest in those eventually.

Yeah that's what I was referring to, just forgot to throw it in there to be specific.

Honestly I'm really kinda swayed to check out a Transgo VB upgrade...you don't see grounding kits chirp 1-2 and 2-3...an automatic chirping...I've never seen that until I saw what VB upgrades can do.

10+ years ago , Automatics were, well, automatic only. People used to hold the car in a gear by selecting 1 or 2 and driving around like that. On some models, you could select all the gears and downshift by doing a D-2-1 shuffle or some combination of that depending on the actual make and model. Problem with this is a lot of trans were not designed like this and would heat up when held in a gear. It was a good way to fry your trans if you drove around like this depending on the design of the trans. I personally know of situations where a trans has been toasted doing this. I did 1 myself on a trans which engages the OD band when holding a gear (creating tons of heat). After a while, it smoked 4th gear in the trans and it became a 3-spd auto unfortunately.

Nowadays, automatics are designed with a sport manual mode, and can handle being driven around in a gear for long periods of time. Shift logic, torque converter logic and internal pressure regulation are designed with this in mind unlike old trans.

So his concern is genuine, but unneccessary with todays modern automatic.



But with that said, i rarely drive in MM. I just don't like it. I've driven 10+ years in a manual trans car and my weekend toy car is a stick. So the difference in MM to a car with a clutch is huge to the point where I just don't like it at all. It doesn't have that direct connection feel IMHO. I know others will disagree, but that's my opinion. It's still fun to use sometimes, so i still use it, but I still can't wait for the weekend to get behind the wheel of my clutch car and bang gears hard and grab rubber in 2nd and 3rd.

Mix of MM and auto - never had any issues.

Better mileage in MM if you short shift.

Most of the time, I drive in auto. If I'm frisky I turn off the vdc and drop it in manual. It's just nice to hit corners in the right gear instead of the computer (that doesn't know to gear down before a turn)

Well the 03-04 models just select the "range" of gears you wanna be in. Basically, the highest gear the tranny will allow it to go in. The 05-06 models actually shift into whatever gear you say when you say it. So you can get a slow roll in 3rd from like 30 mph lol to get a real nice low exhaust note ha.. in my 03 if i floor it with "3" displayed... it will downshift for me. 6MT is next. for sure

I have an 04 and I can manually select individual gears. I believe it was just the early model 03's that had the gear range selection (along with the diff ECU, not to mention that hideous doggy door).

03 and early 04 sedans operate this way. The 04.5 sedans have the newer style shift programming. The 04.5 cars are identifiable by shift lever with button on the front of the lever, rather than the side.
