I often shift 2-3-D manually, just so I can get some kicks out of my Auto. It seems to pull better because I can shift at higher RPM's. Is this bad for the tranny?

 

this will not harm it
remember when you shift this way ,the Transaxle is still shifting automaticlly. you are just telling it when to shift. but it is still doing the shifting.

 

hey try this.....go about 30 into a turn drop it to first floor it while turning and ur car will launch off a turn....here is something alse to try at a 90 degree turn....as ur about to turn drop it to first pull ebrake turn the stearing wheel the other way and thats a maxima drift.....lol ill try to catch it on video...came really close to a car once but all the guy saw was the smoke from he tires god i love my maxima it could handle anything....even me...to bad my 3.2 tl couldnt....

 

No more sugar or caffine for you...sheesh!

 

If you want to shift you shuld have gotten a 5/6-Speed

yeah but since i didnt i beat on the auto....lol or aat least until i get the vbmod

 

PCGuru, the city I live in is not meant for manual transmissions, and I am sure that I would have more sadness than happiness if I had gotten a manual (that is, if I could have found one).

 

I think there's a lot of debate about manually shifting a automatic with no definitive answers. There's certain occasions when it is necessary like traversing up steep inclines or going down steep declines. When you downshift to lowers gears you're basically not allowing your transmission to shift at its rev limit which could or could not be good for your transmission since it overheats the transmission fluid and we know heat is bad because it results in increased wear and warping.

With that said, a lot of cars today offer the "manumatic" shifting in their vehicles of which I have no clue if their transmissions are any different than the basic PRND321 gearbox.

I just think that's its a good idea not to make a habit out of doing it. If you really want to shift your own gears......

 

Hey, could the manumatic feature be the cause of the Acura TL's transmission woes?

 

Upshifting IMO doesn't damage except for the overheating but downshifting manually can damaged it!! it's not like a Manual tranny , you can't rev it before downshifting

Just go it when you want to have fun, not all the time. One of my friend broke is accord(old one's) automatic while doing it (Ok it's a Honda)

greekmax2k1: really great for transaxle men!!!

 

Hmmm, could be, but of course manumatics have been around for quite a number of years. Chrysler and Jaguar has had them in their vehicles for a while and I don't know if there's been problems with those transmissions. IMO I just think they're features that help sell the car and not necessary meant to be used on a regular basis, but who knows. I would think that auto makers would seriously reconsider featuring that option if there's definitive proof that its harmful to transmission life. But I do know a lot of stories of people who treated their automatics like manuals and eventually had troubles with slipping gears and/or complete transmission failure.

 

i dont think upshifting harms the tranny, you just basicly tell the computer when you want him to move up gears.
The downshifiting is the baddd part. i only downshift when i brake realllly hard for emergency. i think that downshifiting WITHOUT pressing anything is not that harmfull, you can see the rpm rise slowly and you dont feel any major overabuse to the tranny. but like i said, i only upshift

 

I have always wondered this.....I always manual shift my car up and downshifts......but when i down shift, i never do it going into 1 because that REALLY jerks the car and feels damaging......my uncle always downshifts his cars (ever since he got his license) and he hasn't had any problems with any of his cars.

 

hmmm... when i race i choose "3" (downshift from D or i start from 3) i love to drive 1-2-3-D (i do rarely) because i have an exhaust with no resonator and I LOVE the sound, epsecially when i downshift... I think the 3 is overdrive so doesnt matter... somebody told that the burnouts kill the tranny. I had bad experience with my 2k2 maxima... WOW GOD!! I killed my tranny... (too much burnouts and redline)... I think 2k3 maximas have stronger tranny...

 

In the case of older Honda automatic transmissions having premature damage, IIRC - it's not because people manually shift their auto's but because of something i vaguely remember of how Honda decided to basically re-invent the wheel on the auto transmission so as to save a few bucks but could never perfect it.

They may be known for their Manual transmissions, but it took them a while to figure out how to make good reliable automatic transmissions.

 

From what I know about the Chrysler autostick in the Intrepid, 300m, Stratus and Sebring and now the PT the tranny is the same as the normal autos but they use a diff computer to control it. When you side the tranny into autostick mode it bumps up the line pressure which firms and quickens the shift which is just like a VB mod on any other automagic.

I read somewhere that on the old 727 torqueflite that one manual shift removed 1 mile of life from them but I don't understand how. Like has been posted on the org before the really killer of any brand automatic is HEAT and lack of maint.

Speaking of "auto-sticks". I think the best one out there right now, in terms of feel and performance, is the one on the TSX.

I've tried several vehicles equipped with 4 or 5spd auto-stick's, most of them are basically regular automatics equipped with the feature and as such you definitely feel the lag associated with it.

However, on the TSX, it feels like it was tuned specifically for the enthusiast. It keeps the gear in place if you want it to and shifting reaction is definitely faster.

 

I had a 1990 Mazda 626 with HOLD system (manumatic, basically), the button to activate/deactivate would be where the "O/D off" button is on most shifters... the manual shifting mapped to the D/S/L selections--it was a 4-speed automatic, but you could not get into 4th gear (overdrive) with the HOLD system engaged, since D with HOLD on was 3rd gear, S was 2nd, L was 1st.
It literally held it in gear, so you could not downshift by flooring the throttle... however if you stopped in D, it would start off in 2nd gear then upshift to 3rd around 10MPH. I did all kinds of crazy downshifts with it, it worked fine... I had changed the trans. fluid though (had 150Kmi with what looked like the original fluid... used the drain/fill/drain/fill/drain/fill method, since it had a drain plug)
That car was pretty reliable for an old junker... finally sold it for my Maxima when its A/C developed a leak.

 

The 04 Maxima is pretty quick too, but nothing is as fast as SMG

 

Abso-fuking-lutely. The BMW SMG system is the coolest shifting system in the entire world. I've never felt anything like it...it gives me wood just remembering what the shifts were like. Instant shifts...

 

Maxpat82 , you can downshift a automatic. Just have to coordinate your feet. Left foot brake and just as you move the lever down from D-2 give a slight blip so there isn't too much tranny shock. I've perfected 2-1, not too bad as long as you do it below 30mph. I've been practicing heel toe with my 6speed for the last few nights.
My FX35's Tiptronic feels sloppy. I can't wait til I take it over to Maximum Tuning for the VB mod.

 

SMG is awesome - though that's not an automatic transmission.

Anyway, compared to the TSX, the 04 Maxima's auto-stick is sloppy.

 

of course man!!

 

I have a question guys... lets say that i have a problem with my tranny (jumps rpms... blah blah) if during this problem put on my car the VB my tranny will be fine? thanks...

 

You can safely manual shift a "automatic", but you will see your fuel gauge drop really fast~

 

Sweet Jesus Gus,...I thought u stopped abusing your tranny like a red-headed stepchild after that reverse roll-back-neutral drop burnout thingy you did. MMMMMM,.....Milky white tire smoke

 

How can burnouts **** up the tranny?

 

Will it harm the tranny if i switch from D-3 and back.?
lets say i am goin 50-60 on the parkway. some a-hole wants to show off. so i throw it into 3 to get more power. and kick his ***. LOVE THE MAX.

 

Nope,...You going from D to 3 in a '02-'03 is the same as a '00-'01 turning off the O/D. Only thing is for us we have a button, you guys get to shift it manually.

 

Neutral drops kill your tranny. Burn outs aren't as bad.But they're still not the healthiest thing for a gear box either.

 

Actually, if i'm not mistaken.

On the 2k2/3, OD is automatically turned off and the gear is brought down to 3 instantaneously when you shift from D-3.

On a 2k/2k1, OD is turned off when you use the button but won't necessarily downshift to 3.

 

You should talk
