OKay, here's the deal...the forums ate my last post so I'll try again (fascist forum)!

Specs on MY car: '98 Auto; just replaced sparks with new NGK plats on Saturday; B&M tranny cooler; JWT intake.

I notice that my car is very sluggish to respond to me hitting the gas when it has been running for a while. I have not flushed the ATF to put in synthetic yet, but it's clean ATF, because I checked. It was the same b4 and after the tranny cooler install. Maybe the gearing is just...slow...but when I go to work in the morning after the car ahas been sitting, it's much quicker to respond to my "hey, i'm late!" call!

I was wondering if an MSD box would help at all, as well? And I am definitely getting the underdrive crank pulley...how does this affect my car's responses?

 

hmm.. i think the 4th gen trannies are just "lazy"
first off when the car is cold the tranny fluid is also still kinda cold and therefore "thicker". when it is thick it causes the tranny to shift a little harder and quicker. once it heats up shifts become noticable slower.

Another thing is if i'm driving around 10-15 mph the tranny holds 3rd gear... i have to hold the gas for a while till it grabs 2nd and it takes a while..
See lime you have to remember it's a family sedan and it's not meant to shift quickly or respond instantaneously to driver commands...

if you want quicker shifts i'd suggest the JWT tranny ECU otherwise known as the TCM. also for firmer and slightly quicker upshifts and downshifts you could get a the valvebody mod sold by Don in Texas.

I have the VB but not the TCM.

I have a 95' gle and the same thing happens to me. I'm not sure if it's the engine or the transmission...

 

The Maxima's transmission is just sluggish from the getgo. If the Maxima is the only automatic you've ever driven, then you will think it is fine. But if you've driven other cars with smoother autos, such as Toyota or GM then Nissan's is rough in comparison.

One aspect is the shift logic. My Maxima has the WORST shift logic. When stopping for a stop sign, if I do not come to a complete stop, the transmission will not go into first gear. So, a rolling stop will produce a starting acceleration in 2nd gear. Very slow. But even worse is if I am making a quick rolling stop. Then the car will end up accelerating from stop in 3rd, then when I give it more gas, it will *clunk* into 2nd. Very unrefined.

 

yeah it's true...hmmm...anyone try driving around in d2? hehe ... not highway mind you. I find myself making sure OD is almost always off...I am a punk! I like to drive fast muahaha. Too bad I don't have the $$$ for any o those hardcore mods right now. ANyone need web design skillz? LOL ... I need to pimp myslef out......

I know it's auto..but...and Ant95 is gunna make fun of me...I am eventually GOING TO GET TWIN TURBO, so I wanna stick with auto for that.

 

D2 is not good , leave it in D
OD off is ok but leave it in D you will save gas on the highway
Driving fast is bad .. mmmmmmmmkay , i don't drive fast never ever never
pimp yourself out .. umm i dun tink this is good idea
web design, yeah make me a web page :P

make fun of you .. i would never do that
the day you get twin turbo's on your car is that day i buy my neon yellow quadruple turbo McLaren F1

WHy not a good idea? You too far away? ^_~

Heheh okay what mods are you gunna give me for your webpage? hehehehe.

Wow you must be swimming in dinero, Ant, cuz in a year or two I'm getting the TT.

 

Anyone know if an MSD box will also help? Or is that a waste of $$?

 

The Maxima's transmission is not adaptive, there is no true shift logic (yes, its a rather old design). Lime, when you say sluggish, do you mean off the line (which can be attributed to your Popcharger, is it slow to respond in gear (what replacement sparkplugs did you get, the same as OEM?) or slow to respond between gears (which is normal up to a point). Please elaborate.

 

Lime: After I changed my sparks my car felt sluggish. I changed the fuel filter and that feeling went away.

Medic: The lip is looks good.

 

Y tank you, Deezo. Its actually a whole body kit, but I haven't lowered it yet, and the side is ridiculous looking, so no side pic until it is done.

 

Come on man!! Show everyone how it looks from the side.

 

Patience, grasshoppa, patience.

 

I can't even talk. I am not going to be able to do any real modding until next year.

 

You mean to say that the car in your sig isn't yours?

 

if you compare it to honda's (odyssey)automatic its really good, with that automatic you either shift SLOWLY @ 2000rpm or 3500 or 4000 or redline nothing in between unless you let gas off completely. TO make things worst, it has ultra tall gearing and it doesn't like to downshift, when I'm @ a stop sign adn roll
its in second and the TC will rev to like 2500 and slowly pull the van away, to make things worst that van is v-tec and has no low end. so I guess I'm like the only one here thats OK with maxima's tranmission.

Last week I was driving home and I tried to switch lane by passing a car beside me that was going pretty fast, I floor it at like 60km/h and it stayed in second @ like 3400rpm, I don't know what happened but the car forgot to downshift, I know if you redline first it'll bring u to 3900-4000 rpm in second when you shift. Do I need to reprogram my ECU or something??

 

Honda's autos are horrible, but they do make some really good manny trannies.

 

UHH....(heavy sweating)....UHH....(cracking smile)..Uhh, Yeah?

 

Ah, it's not consistent...usually after it's been running li'l while, or after I turn it off/on, it just seems like I have to wait a few seconds before me flooring it gets the response I was hoping for. I used OEM NGK plats...that was recommended, and I'm not using NAHS (hehe NOS), so I felt COOLER NGK's would be a waste of $$. Off the line it's pretty good usually, as I know how to make my baby go go go! ^_~ Seriously though, it's kinda depressing because there's no way I can save up to upgrade the VB/ECU stuff right now. I am hoping the underdrive crank pulley mihgt help a little...?

 

Lime, did you change your fuel filter? If not, try that. Every little bit helps.

 

Not yet...I think I will need help because I have ABS. I don't think anyone will help me. DO you think when I got to have my ATF flushed & replaced with synth, they can do it there too? Should I supply them with a special filter?

 

Have Maxima...Will Travel

give you mods ? umm..you could have my blue turn signal bulbs that i don't use anymore cuz cops kept pulling me over when i had them

if you REALLY want to make me a webpage and there is no stopping you then ok fine ..

Ant has no dinero .. if i had dinero i'd get NOS right ? hahahahahahahahaha..
besides i just spent all the money i'm allowed to spend right now on another toy ..

and if you plan on TT'ing your max i hope you have enuff money to buy ANOTHER car cuz your max is gonna be in the shop for a LONG LONG LONG time

if you really want more tranny perf you need VB or TCM .. thas it

I am 50/50 on your comment. I own a 97 GXE and I have driven Volvos, Benzos, Saabs, GM and Ford autos, and Toyotas to name a few and I am very impressed with the Maxima's auto in regular driving conditions. I don't know about everyone else but you can barely feel it shift in my car. For everyday driving and road trips the tranny is beautiful.
On the other hand:
For racing and sport driving, it's not so good. Yes, the current Valve Body doesn't allow the tranny to shift when you think it should therefore you will lay on the gas harder to downshift but for highway driving, I don't think the quicker shifting VB is comfortable(depends on what you like for highway shifting). If the VB upgrade allows more sensitive shifting, it may cause the driver more aggravation that comfort(like me). The 97 V70 GLT I used to drive had Econo/Sport/Winter mode buttons on the center console so you could control the VB in the transmission. Sport mode was quicker shifting which was nice in the city but on the highway it was a pain. I didn't like Sport on the highway because when I when I am cruising I don't want to feel downshifts with every move and every incline therefore I would always switch the VB back to Econo.

I guess what I am getting at is that is depends on what you are looking for. If you are a lead foot and need quicker shifts the VB mod helps but if you are a road runner like myself, the VB mod might aggravate you. Just my thoughts.

 

Ant: damn and everyone voted you the cutest too...if only you had $$ LOL jk.

Deezo: well I can't afford them...I am hoping the UDP is decent enough for now. Someday maybe....

As for TT...yes I know I will need to have a secodanry vehicle to travel around it...I got that covered.

 

Your cute , they should want to do anything possible for you.

 

awwwwwww...yeah I wish they'd do stuff for free........
