Auto 4wd?
Bird
looks like now that Im a cripple Im going to be FORCED to drive an
Automatic..
I would rather eat rat poison than drive an Auto...
So my question... whta are Automatics like off road? Are they as
lifeless as they are on the road?
Daryl Walford
situations an auto is better than a manual.
Sand driving is one example.
Towing is another.
Most reports I read on the Discovery diesel suggest that the auto is
better because it seems to lessen the effect of turbo lag.
A friend has a 1999 auto Patrol and I've never heard him complain about
the transmission.

and I now have an auto. I definitely prefer the auto. It's easier to
drive in town, and is great in the bush. It handles the rough stuff at
least as good as the manual, and in most circumstance better.
Sand driving is a breeze, as is slow stuff over rocks, etc. The only
drawback is the reduction in engine braking when going down steep hills.
This is no big deal, just means you have to use the brakes with a bit
more finesse than usual.
The 80 series petrol manual was a bit of a pig to drive. Because of the
amount of backlash in the drive train they are very tricky to changes
gears smoothly. Even after driving it for a few months, smooth changes
didn't seem to come naturally. I thought it may have been just mine,
but I drove a few others and they all seemed to be the same. The diesel
manuals seem to be not that bad though, probably due to the engine
output being a bit more sluggish than the 4.5L petrol motors.
My two previous 4WDs before the Cruisers (a Patrol & a Pajero) were
manuals, but I don't think I'd ever go back to a manual now. My advice
would be however, that if you are going to go auto, make sure you get
something with a bit of zing. An auto in heavy vehicle with a gutless
motor is not a good mix.

I agree with Rob & Daryl, don't knock one till ya try it.
I drive a 3 litre V6 Challenger with a slush box. At first I mainly got it
for the missus to make it easier for her to punt around. Haven't regretted
my decision for a minute. The engine/auto combo has enough stick to leave
sedans scratching their heads when you kick it in the guts at the lights and
makes hill climbs in the crumbly stuff a real breeze. I use the gear lock on
steep decents and don't seem to have any problems when working out with the
guys using manual gearboxes in my club. I also agree with the other comments
on this subject re- making sure you get a good engine match for you
slushbox. You might say you're cippled but I'm sure if you select wisely,
you wont find an auto the handicap you think it might be.
Cheers.

Well of all things my 90 Hilux is an auto,,, the 1st auto ive had since i
HAD to have one... and i have to admit it goes great
Carries the engine & transmission straight out of a V6 commodore with a
switchable lock-up torque convertor...can still get a fair amount
of engine braking with that.
Darryl Tunesi
I also have to agree with all the other guys (especially the comments on
engine power) except that for some reason my auto forerunner just seems
to be just slightly lacking in the "fun factor" compared to my old
manual 70 series Bundera.
Admittedly the forerunner is a totally different class of 4wd and
probably much heavier but the Bundera was down about 50hp on the
forerunner and it "felt" just as capable off the road.
I'm sure it's all pretty subjective though, perhaps a modern 4wds are
too luxurious for their own good when pitted against vibrating,
bouncing, noisy Bundera

thanks for the brains here for easing my terror...
Now .. Since Im only FORCED into this auto thing, im thinking of buying a cheap
4WD (its also my first 4wd, so I expect to ding it off road), and when Im healed
buy my dream 80 series thats at Rockdale in a car yard...
What is the thoughts on the 60 series? anything to look out for Problems wise??
I have found one for $6999 in a car yard, and that would do me at the moment. I
dont want to spend a fortune on somethin gthat Im not going to keep for ever...
Thoughts??
Doug Maxime
$10,000 was a real shitheap...you might be lucky and get one off an old
bloke who has had it for years, but chances are that the 60 series springs
are FUBAR...(toyota put soft springs to make 'em more like Toorak
tractors)...look for how far the shackle is from the vertical, the more
vertical...the better the springs are...
We had two FJ 60 (3F) '85 Sahara's...and they have been faultless (except
for radiators, batteries, valves)...yeah...watch for burnt out valves...its
a problem that Toyota fixed under warranty for us...but it wasn't in every
model...the auto transmissions are fantastic...never had a fault...dunno
about the manuals though...don't have one..
watch out for rust of course, and dodgy LPG conversions if applicable...
I gave up looking for a 60 series and bought a troopee for $7.5K...an '84 V8
manual...not exactly a comfort vehicle though...
good luck...

look VERY carefully around the roof gutters
this is where they rust and it's not cheap to fix

automatically but only once the vehicle has reached a certain speed... but
mine has a switch in the console so its totally manually controlled.

The switch that you have, is that part of the commodore auto box, or
is it something that was retrofitted?

as the T700 auto box locks up at around 70kph
but is is just a sensor which uses the speedo input to operate
so should be easy to tap into

> So normally a torque converter would only lock at high(er) speeds?
I have a friend with an XT commodore and it seems to lock at about 80kph.
Another friend with an EB ford complains because his only locks at about
95kph. Has to sit on 100 to keep it locked. Drops below 95 and it unlocks.
Must be factory set in the auto box electronic control system or by the
auto box manufacturer.

fitted an LED indicator on the dash to let me know when its in the LOCKED
posotion.

transmission tries
to change gears (like gear crunch)
or do you only lock the converter when you have locked the transmission on
low?

the Torque converter is a fluid drive system
there is no mechanical connection between the front and rear sections of
the converter
a converter consistes of two finned plates, and placed very close
together
when the engine turns it spins the front plate which picks up the trans
fluid and throws it against the rear plate, the force is enough to start
the rear plate spinning, similar to spraying water at a fan blade.
There is always a difference in speed between the the 2 plates, this is
what makes an auto un-economical, now if you add a locking mechanism to
the converter so that to two plates are locked at the same speed then
what you get is a direct drive to the transmission, thus making it more
economical and getting faster response to acceleration, and an added
bonus when used as described by Rod, it gives good engine braking

locking the torque converter otherwise it would be like changing gears
without using a clutch?

there is no need to break the drive to change gears
as the new autos lock their converters at around 75kph and as you know
in some of the larger cars you can be doing 75 in first gear, the
converter will lock no matter what gear it is in and will still change
through all the gears, it all relies on the use of the fluid and the
valves, basically a hydraulic selfchanging gearbox
explaining how an auto box does it's gear changing will take quite a bit
of space so I might suggest you search the web for info on them

You might have a point with the latter, if auto's didn't come witch such
long 1st gears....often close to 2nd gear in a manual....have fun downhill,
even with a locked torque converter....8-))

Are any vehicles standard with locking torque converters?
or are you discussing mods?

and as most late model 4 speed autos have lockup converters that lock
only after the car has reached a certain road speed(usually around
75kph) what Rod did was modify his so that he could lock it via a switch
on the dash for when he is using low range when going down very steep
hills so that the engine will give full engine braking
