car has shit itself...
hey guys...
lets see, last friday i got a fault code pop up saying check powertrain in my vz calais, i went to kelly holden on monday, they cleared the code and said there was nothing wrong with it, just a computer fault. 2 days after they clear the code my gearbox shits itself... finished work today, got in my car, drove 100metres down the road, turned a corner and it just started reving instead of moving. there has been no signs of a bad gearbox, no slipping gears, no noises, nothing... then all of a sudden it dies.
Matty
feel free to comment people.... lol

sounds like you have a problem...
could be the solenoids that change the gears.in the gearbox.
Matty
well i have a mate who is an apprentice mechanic. he reckons they are fine. do u reckon the body control module could be the problem? cause i know i need it fixed or replaced. but didn't know that could be the reason for the gearbox issue. like its just not selecting the gears. its not making unusual noises or grinding or anything, just basically stays in neutral even when its meant to be in drive, reverse, whatever.

that sounds like its more mechanical like a buggered torque converter or something. An electrical ECU cant stop a mechanical linkage from working
Matty
oh ok then. got any idea wat im looking at price wise to fix it if it is a buggered torque converter?
Donati..Whoa Green
A new torque converter can range in price, but generally about $500ish. Installation is a bitch though, because you have to drop the gearbox.

oh. well im not gonna bother doing it myself, i'll be going to kelly holden. damn stupid new cars, every last thing being electrical..
The torque converter isn't strictly a mechanical connection between the gearbox and engine, it is a fluid connection via an impeller and propeller and it locks up above a certain speed with a clutch which at which point it becomes a mechanical connection.
This may sound like a dumb question but how much fluid is in your transmission and have you tried selecting the lower gears manually?
Matty
fluid is fine, and yeah i have tried everything. from low range, 3rd, 4th, drive, reverse, active select..
:):):)
just as i expected.....
it seems.. to be.. broken

Could be a faulty transmission computer. I've accidently half flashed my transmission computer with VCM Suite and unplugged it during the process without realising it one day............ got in the car and was going down the road, it lol wouldn't go in gear, just would rev n stuff ........
So the TCU was only half flashed, only reason I think it could just be a buggered TCU(based on my experience with the TCU being virtually buggered). Maybe unplug it and plug it back in, the VZ's have a problem where the aircon drips down onto the main connection cable for the TCU.
My 2 cents...

how can you check the fluid level on the box tho, I thought they were a "sealed" unit and don't have a level gauge at the top? (yes I know the oil can still be dropped and replaced but thats all at the bottom end), but I'm not that familiar with the 5 speed so I may be wrong.
Yeah you can't check the level with a dipstick, you can only unplug the filler and fill it up will oil till it starts to overflow out of the overflow plug hole which indicates that it is at the right level. Some BMW auto boxes are the same. (something along these lines anyway as my Mechanic has serviced my 5 speed twice.
Matty
well im guessing the fluid is fine cause there are no leaks lol. maybe they kinda ****'d something when they cleared the fault codes the other day. hmm i dunno, well its there now, hopefully they can get back to me asap. i was told from my mate (who is a mechanic) that the gearboxes in the vz's are a tuff box. but i spoke to some guy who specialises in auto transmission and he said they always break. so yeah, i dunno. its so annoying hearing different shit from different people. just hoping its some kinda computer fault, not a new gearbox. if i need a whole new box i may aswell go all out and get a 6speed manual in it lol.
Donati..Whoa Green
Don't the VZs run 4L65E. They are tough and it would take a fair bit of punishment from a V6 to break one. Just like the 4L60E, people abuse the shit out of them day in day out and they hold together. The fact remains that they were designed to pull small trucks, and small V6 is nothing in comparison.

When an auto lets go it doesnt give much warning. I'd say the box is buggered. Needs a rebuild.
Guys the VZ's use two different boxes the 4 speed (4L65E) and the 5 speed (5L40-E - in the Calais and SV6). I have a feeling the 5 speed is not as tough as the 4 speed.
Matty
oh...
well i still dont understand, it worked for 100metres driving down a road, turned a corner then it stopped working. thats wat im not getting at the moment, if it was the gearbox u'd think it wouldnt have gone from the start. not until i turned around a corner. mind u, i wasnt giving it any at all, driving perfectly normal. probly even a bit slower then normal.

FYI theres 2 types of 4 speed box in the Zeds, old school 4L60E with 'refinements' and 4L56E
I believe the stronger 4L65E was fitted to 6 litre V8's / HSV's and moved onto the VE V6 range, but in the VZ V6 its still the 4L60E, or in this case of a Calais (or SV6) its the 5 speed 5L60E.The hydra-matic 4L60E automatic transmission is fitted to vehicles with either V6 engine or GEN III V8 engine. The mechanic and internal electrical operation of the transmission unit is identical for both, however there are two controllers used, transmission control module (TCM) for V6 and powertrain control module (PCM) for V8

On this topic I've heard the 5L60E isn't as tough as the old 4 speed, their pretty much on the limit as they stand, but yeh I don't know too much about the 5 speed.
Matty - we can take guesses for the next 3 weeks and may or may not get it right. At the end of the day your best off getting someone to look at it. It may be electrical, it may be mechanical, we'll never know.
Mine went the same way. 100m down the road, turned a corner, stopped at the lights, went to take off and nothing.
From Memory there were Torque Converters that had problems with shearing the shafts off. Sounds like either that or fluid low or gone.. But you say theres no leaks anywhere. I would take it to a Transmission joint rather than a Dealer. Usually the Dealer will take the car & send it straight to a tranny specialiist down the road!!!! Check your fliud lines to the cooler under the radiator , maybe a line has come off & pumped all the fluid out onto the road. Good Luck , but allow about $1700 to get an exchange unit fitted......
Matty
yeah. well i got called today about it, they reckon that the clutch plates and shit themselves, bla bla bla. need a new gearbox. they quoted me 3500 for another one. the car is gonna be off the road for a few months so im just gonna do a full conversion on it. put a 6 speed manual in it.
