Auto reliability

[shyr33]

hey guyz im just asking a question on behalf of my mate, he has a auto 1995 r33 with a fmic and he is wanting to make more power out of it with the usual mods exhaust, fuel pump etc but he was wondering how strong the auto box is? stronger then a manual? and if anyone on here has a auto making some power how much and are they reliable?thanx

I blew my Auto

I blew my Auto

How did that happen? lack of maintainance? or just totally abused?

[Guilt-Toy]

i abused it a bit

Used to use the snow button to spool up power + it did 160,000km

I heard they cant handle to much power anyway

[knore]

Not when they get hot and arent maintained

what do u mean by used snow mode to stall up, snow mode means it takes off in 2nd

and what did you do after? new autobox?

[Abo Bob]

I hear that only some R33's come with an auto fluid cooler. All the R34's do. If it doesn't have one or it's pissy small then get one. Mine has only overheated once and that was on about lap 12 of Wakefield.

[lukits01]

I know my series II has a fluid cooler in front of the radiator

Its handling 200rwKw atm

Anyone know wat mods is needed for the slushbox to handle more power?

Higher stall converter, new clutch packs? how much?

[WazR32GTSt]

i don't think the auto's are as bad as people make out...

[Slide]

my lines auto and pullin 208.9rwkw and like my number plates suggest it gets kicked in the guts every day

the only things that are wrong with mine are

coilpacks

ignitor coil

starter motor

alternator

oxygen sensor

(((((Think it was struck by lightning))))) jokin just a lemon

but except for the coilpacks and ignitor coil these are pretty auto unrelated problems

that will be fixed on tuesday

i am also curious about the spool up in snow

i usually rev it upto about 5000rpm in nutrual the slam it into first

but only in the wet or when racing and only cause i can get a replacement gearbox for free

My auto is running strong at 200rwkw.

For serious questions about whats possible and how it should be done, ring MV Automatics in Adelaide. They added a trans cooler and shift kit to my auto and gave me the impression they were good for close to 300rwkw. There are mods you can do if you are running an auto with over 300rwkw.

Did your car come with a transcooler? or did you just upgrade to a bigger one?

What did the shift kit contain btw?

[4door_Sleeper]

Lukits01 - yes my car came with a cooler, but I had a bigger on installed. (like the standard intercooler but on the drivers side)

I am not sure what the shift kit contained as it was purchased and installed by MV automatics. Shifts are now a lot tighter when under acceleration, and the tyres chirp during gear changes.

yea i have found that a big trans cooler makes the world of diffrence my R32 did not have one it just cooled through the radiator piss poor. My R33 all ready has one but it's so small i will be changing it out next week i will be expecting the same change

Push the snow button put food on the brake and stall it up - wheels wont spin because its in second gear and when your ready to take off press power and let go of the brake at the same time time and you get some interesting launch's usually wheel spins off the mark dont do it too much cos the clutch packs dont like it (As i found out)

I put a 5 speed in it after it blew up and never looked back.. even though im having troubles now as the Pedal box broke under the clutch cos of sydney traffic and a heavy clutch.

But yeah cars i was just beating before in the auto - I was smashing them in the 5 speed - remember that auto dif ratio's are 4.39:1 where manual is 4.11:1 so you will be quicker off the mark then the 5 speed released skylines.

[4door_Sleeper]

A good auto will still change gears faster than a manual, and will consistently do it at the correct RPM. Giver a choice and all things being equal the auto should always beat a manual.

NB - I am assuming the manual has an upgraded clutch and the auto has had a shift kit, and that both cars have similar power.

[r33fred]

R33 auto will handle it easily. I have a series 2, has small oil cooler out front.. They use the same auto box in the 4 x 4 patrols so they are plenty strong. Need good full synethic fluid though.

[shyr33]

thanx for the reply guyz my mate only wants about 190-200rwkw so i think he would be fine

hey guys, i just changed my trans fluid. there was heaps of gold sparkling crap on the bottom of the pan together with a 5 cm piece of dipstick. must of been done by the previous owner coz the current dip stick is in one piece. not happy.

[4door_Sleeper]

that isnt a good sign.

Lucky autos are dirt cheep if it turns out to be a worst case senario.

Changed automatic fluid today, car feels alot smoother and a little faster

it took me awhile cos i took the transmission cooler off and gave a full degrease, flush and replaced all the rubber hoses.

I removed the in pipe from the cooler and attached a length of hose, then turned car on and watched it spray out

Fluid was horrible! When i check it every now and then with the dipstick its been a perfect pink color, but once it was out in a bucket it turned out to be a brown color (not because of the color of the bucket )

I managed to drain 4L on the dot, going to redrain again next week.

Used castrol transmax z $59 per 4L :kick:
