Hey Everyone, i've been seriously looking at selling as i absolutly hate the Magna Auto transmission. I really want a Manual car, but really like the look of Magna's. Aside from a full manual conversion, is there anything that can be done to the stock auto box to make it better?
I've noticed on my car that if i really push it hard and do the changes myself it has no guts at all between 1000 and 3500rpm. in those rev ranges my car is the most pathetic thing ive ever driven. after that it definately moves with some urgency. Is this a gear box problem? or is every magna just built with this "dead" spot?
My car is completely stock no egine mods at all.

any help is appreactiated thanks heaps

I've got a manual, and I think it's just a dead spot int he engine. After 3,500rpm it moves fairly well though.

yeah my magna 3.5l is pritty gutless below 3,500rpm but after that she starts to move pritty quickly the 3.0l auto is better below 3,500rpm actually.

wow so it must just be a thing with Magna engine's cool thanks :D

id highley recommed doing a CAI with K&N Panel filter,

it will improve responsiveness and it will feel alot more powerfull for the money it costs ya,
it also in my case dramatically improved fuel consumption

im loving paint at the moment, so basic.

nice body kit ;)... would evo bonnet vents provide the ventalation needed to reduce the temp of the block, plenum and other parts? also would it be wise having a smaller vent off the side for cai would u get more air from a bonnet cai than a bumper cai?

ive been curious about that myself actually! :D

the 3.0l auto is better below 3,500rpm actually.

doesnt take as long to get to 3.5k either coz they rev a bit harder to :) just lack the torque :'(

I noticed that most OHC V6 motors are a bit flat below 3k but then rev like crazy above that

if i need a bit more off the line i hold first (auto) bring it up 2k and then launch it.....

probably not good for it but hey i just build a better one when it goes...or a manual....

Thinks "I wish i could find a sequential 6 sp for the magna"

Lovin' my 3.0L manual...... :D :badgrin:

One word: torque converter.....or headers. Headers would be more accesible. Intake isn't gonna improve low-end power.

thats 2 words actually but hey... .jus messin with ya.. by the way its dblock from diamanteowners

Oh ok......Yeah I can't count - I am senile.

the 3.0l auto is better below 3,500rpm actually.

I disagree, at least in my experience. I used to drive a TH auto 3.5 for work regularlly at the same time I had an auto 3.0 TF. While yes the 3.0 reved quicker, the 3.5 had noticablly more pull below 3.5 than the 3.0.

Taking off from a standing start without using the brake to stall up, the 3.0 would mearlly chip whereas the 3.5 would spin a tyre or two almost everytime. :P

my 3.0l deffently spins a tyre or 2 aswell

My sisters standard auto 3.5 spins the wheels off the start. When I drove it I thought there was nothing there down low at first, then I tested it aginst a friends VY exec and it pulled away from the start. It's not there is nothing there there is just so much more starting from 3000rpm

your saying the VY exec was beating your sisters 3.5l auto did you start catching up after 3000rpm

Ah sorry I ****ed that up, I blame lack of sleep. I pulled away from the start, even more so when it reached 3000rpm, that when the Multipoint changes things isnt it?

Hi Broke and all
I've found that you can improve the tx with a service and / or an additive to reduce friction and temp. The auto tx has temp sensing electronics and adjusts the ECU accordingly.
For the engine, check the operation of the PCV and EGR if fitted. I was able to improve my TJ t/t with a cold tuning gasket on the throttle body, a fuel injection kit and an ignition earthing kit which all combined to remove the flat spot. Now it starts moving from 2k RPM. I have a Lukey sports rear muffler but no other exhaust mods :cool: .

The problem is the cylinder configuration: the bore is larger than the stroke. With a short stroke the piston speed is high but the travel is short. Any power from combustion is spent quite quickly once the piston reaches BDC and returns around the crank. This type of engine favours higher rev work as most of it's power is achieved later in the rev range. The 3.5L has a longer stroke but is still under-square. But you can still notice the soft spot.

My old man's BA XR6 natch asp still sh!ts on my AWD with 200kg in the tray :(

The BA 4L straight 6 has a longer stroke than it's bore and has a HIGHER compression ratio - 9.7:1 vs 9.0:1 in the Magnas. Still runs on ULP but achieves 182kw and 380nm! With a variable inlet manifold this torque is hard to overcome.

Tell me about it, you take off from the lights at normal traffic speed and the engine never revs over 2K... lol

a stock bA falcon has 380nm of torque??
damn ive wanted a BA for ages i love the look of them, i had no idea they were quite so powerful

Forgot to mention that His XR6 is a manual too so less drivetrain loss = more to the ground.

Holden have only just caught up to fords torque with the VY's. They now make the torque of a 1989 Falcon :P

is that just due to the fact fords are 4.0ltr and the holdens are 3.8ltr?
or do ford just make better engines in general?

I'm not touching this lol

I'm not touching this lol

haha ok i dont want to start a war of opinions. :)

fit and fpr that'll solve your problem

hey get your own name :bowrofl: kidding dude welcome.

errrr. joe king.. jo king... brett.. lomgna.. wtfg

errrr. joe king.. jo king... brett.. lomgna.. wtfg

not me choonga this guys from W.A lol

haha my twin

Oh Brother :doh: ... not two of them!

the clubs not big enough for two of me and choonga :bowrofl:

I was reading today in the newspaper about the new BF, they skipped from BA to BF because BB is associated with bigbrother, BC means before christ and BD is offensive in some languages... anyways the point i wanna get across is, is that the new BF fuel consumption is like 10.9L/100ks!!
Thats insane.
And the new Devil R, which is somewhere near 300kws im sure fuel consumption is 14.1L/100ks!
