Shifting a Sport 5AT?

[quote=Mead;131740][quote=RedAndy;131712]b) I wish it had one more gear for long distance crusing - above about 80 mph (~3900 rpm) it starts gettig buzzy.....
No, the gearing in the automatic trans is somewhat taller. Most people seem to observe 3900-4000 RPM at 80 MPH in the manual.
Automatic at 80 MPH shows 3000 RPM in my car. At 90 MPH it's around 4000 RPM and really feels like it's in its "sweet zone". My AT makes me wish for higher speed limits. This car seems happier at 90 than it does at 70.

hmmm so 3900 rpm at 80 mph... doesn that go for 5AT also?
I do 650 mile interstate trips every now and then

My car on the high way just moves. I agree around 4k is the "sweet zone". Which is when the VTEC is working. When your in S mode and you rev her out, she moves well. I love this car but the paddle shifters make it that much more fun. Would of loved to get a manual but couldn't wait 5 months. But, the paddles make up for that. I don't regret getting an auto at all. Now Im just waiting to get the JR supercharger. I think with the charger and the paddles its gona take this car to a whole new level!

If you're closing in on the car in front of you, or coming up to a turn and need to slow down, is it better to tap the brakes, or to downshift? If its going to cause wear somewhere, I think I'd rather wear out my brakepads than the transmission or engine.

This definitely doesn't sound normal. If the rpm's are going up but the car isn't going any faster it sounds like the tranny is slipping. 1st gear should easily get you past 20 mph, 2nd gear should get you past 35. I don't remember axactly the speed when I shift but that isn't normal. I would take it to the dealrer and have them check it.

I was wrong about the speeds, its 17 for first and 25 for second. Could this slipping be related to my low mileage of 24 mpg, 100% city?

If your tranny is slipping it will definitely affect your mileage. It will also fry your tranny in a very short time. If you reach a speed where the car doesn't increase it's speed but the engine goes faster and faster then you have some slippage which translates into friction and heat. Definitely have a service shop test drive it to be sure.
#87
It does continue to accelerate, but slowly. Should it accelerate at the same rate throughout the whole range of rpms? Mine certainly doesn't. I will have it looked at if that's the case.
#88
Well, I made an appointment with a dealership to have this looked at. I'll have to leave it there for at least a day, but the guy told me that they can get me a loaner car for free. Is this something all dealerships do? This isn't the dealership I bought my Fit at.
#89
There are numerous variables that can affect the answer to that question. Under what conditions are you driving when this happens? Generally, no, it will not accelerate at the same rate throughout the RPM range...this is a function of torque & hp. Although the gear multiplication of a manual trans and differential is practically linear, the torque converter of an AT trans is not, nor is the power band of the engine. The lockup converter function adds to the complexity. Are you sure you're not just experienced the engage/disengage feel of the torque converter?

I am using Sport mode with the paddle shifters, so I am not feeling anything related to it shifting automatically: it is holding the gear I have selected.

Maybe I am, but I wouldn't know what what feels like. All I know is that in first gear, once I hit about 20 mph, at 3000-35000 rpms, I accelerate very slowly, if at all, even on level ground; and in second gear, once I hit about 30 mph, also at 3000-35000 rpms, I accelerate very slowly.

Yeah man. You car is fine. 1st gear will rev to redline (which I don't suggest you do a lot) but it is limited on making the car go because of the ratio of the gear. Which it is made to produce more torque to get the car moving. When I drive from a dead stop I usually shift from 1st to 2nd at around 3500-4000 rpm unless I'm really driving her then redline's the limit. I pretty much treat the car as if it were a manual trans. But, I am very careful when I down shift. If you use good judgement and the brakes you can figure out the point on the tach in which it down shifts the smoothest. Ive been using sport shifting since day 1 and I have 9200 miles on her. So far I love the trans in this car. Once you get used to it you can have lots of fun. Plus it shifts so quickly. I'm a subaru tech and I think that the 5 speed auto sport trans in the fit shifts better than the 5 speed auto sport trans in the Legacy GT. The Legacy has a slight delay were the fit is instantanious. Now this is saying a lot considering the difference in the prices of the two cars is about $15,000! Thats impressive. The trickiest thing about the sport shifters is shifting while your turning. Once you get that down packed your good to go!

New Owner ? about tranny
Ok - Fit Freaks - I have a question. Just got my Fit Sport A/T over a week ago. I've never owned a Honda before just Ford or Chevy kind of girl. I have noticed when I put the car in reverse there is no backward pull like I would normally get with Ford. When you shift to R it was a definite roll back. The Fit I just hold down the brake and put in R and it is ready to roll with no clank! Is this normal? Hope this is not a stupid question but I am used to the definite backward motion when in R. Also is it normal when you pull out and are in Drive - you don't give it any gas but it seems to not move forward as fast as my other vehicles who were all 4 cy. motors. It is moving but just not fast until I give it gas - Just thought I would throw out the question to make sure this is normal and nothing I need to check into. I've checked all my fluid levels just to make sure everything is in good shape and all is fine with that. It is running like a top otherwise - loving it! and enjoying the fun factor!
Thanks,

Its an import. Imports drive differently from american cars. I have a M/T, but I can tell you that my dad's old Taurus (besides driving like a turd) had a much less fluid transmission than his CRV. The Taurus would take off at a good 10 MPH or so when you let go of the brake, while the CRV just gently drifts forward. The CRV shifts smoother than the Taurus ever did, too. I'm pretty sure its normal, its just a different type of car with a different type of driving experience.

Steeldog, it sounds like your car must be downshifting to run at 90. If 80 mph equals 3000 rpm, then 90 mph should be less than 3400 rpm. Perhaps the AT Fit can't pull 90 mph in 5th. I don't know, I haven't taken mine past 80mph, I'm over 3000 miles now, maybe I should give it a try...

It will, however, get there a lot quicker in a lower gear. I believe that in manual mode, it will hold 3rd gear past 90 mph. I wish I could remember, I ran it one time to find out where the fuel cut-off was at, and it seems that it was around 93 mph?
Interesting note - I discovered an interesting ressonance with my car at 114 mph one time, in 4th gear. I don't know the source at this time. I might have to conduct further testing (next time I can get to the track) - LOL!!

wyy183, I would figure as much. My post was more about how if 3000 prm = 80 mph, then 4000 rpm = 106 mph. I was trying to give steeldog an out on his post. I would be very surprised to find out that a Fit had too much resistance or too little power to pull 90 mph in 5th gear.
