wondering if you can put a lsd on a auto without any problems
what exactly does snow mode do (does it lock diff)
does sporty mode just change gear quicker
cheers
-
hi fella well basicly sport mode holds the revs longer and higher before it changes up and snow mode makes it pull away in 3 rd gear to stop wheel spin if i remember,auto or manuel a lsd does the same thing.

its just im going to do a manual conversion, already have lsd but will be getting gearbox in a few weeks would i be able to replace standard diff with the lsd until i get other gearbox

LSD will work fine with an autobox.

i was told it might take the power down abit, doesnt realy matter to much as long as it doesnt do any damage

Wont do anything to the power, it will drive like a normal Diff untill the LSD kicks in (TC off), the only damage it will do will be your rear tyres if you get addicted to playing with it.
Driven a few Auto's with LSD no probs, just with a Manual box its more controllable.

Well yea, there is that, but dont forget the front of the car is still attached and moving as well so a lot depends what thats pointing at also.

thanks for all the repies and so quick as well. cheers. i will be fitting lsd over weekend

Are you renewing the Diff Oil or is it all intact?
-
i will be putting new oil in myself

Not that I know much about such things but advice I've picked up on here is to use the correct oil (normally from VX) and the correct diff oil additive. Something about generic oils cream crackering the diff internals if used incorrectly. If you have a search about, no doubt you will find what I mean.

my mates dad works in vauxhall garage and he is getting it for me, so hopefully he will know what to get

No comment.
-
id rely on the haynes book of lies if anything and get it yourself from a dealer lol
-
I'd look into what diff ratio you want first, as it will be different between and auto and manual gearbox. ;)

How would I find out if my Omega has an LSD or not ?
Thanks

It won't have one ;)
Only some ex-police had them

Send a PM to Jimbob including your chassis/vin number and he will tell you what it left the factory with. :y

It might. As I understand it, it was an expensive option for initial purchase.
-
Cheers for that will PM my chassis number.
Also the snow mode button to left of gearshift, how do you know it's activated ? I have no lights coming on when I press it.
Thanks

It will only work in drive. Also there is about 5 omegas that I know off that have LSD that are not ex plod. Going to fit mine tomorrow so tat will be another one with LSD. So maybe someone might have put 1 in your car aftermarket so it won't show that it left factory with it.

As I recall, when in drive, button itself lights up/gets brighter when pushed/activated. No indicator on the dash though, if thats what you are thinking. :)

It is on a dim light all time but when in drive and button pressed it lights up bright.
As hotel21 said no indicator on dash

If it doesn't light up, other than the bulb being blown were would the problem lie ?
-
IIRC the winter mode button will only operate when first shifting to drive after turning the ignition on so if you drive off then try it, it wont work

Correct. only really works in drive, once you change gear manually it will switch off. used it tonight, waste of time if Im honest, only real option for me when I got stuck was 1st Gear, TC off, loud pedal and point the car in the direction you need it to go.
-
Hi looking for a bit of advice my car just now is at 110k just bought it gear box sometimes holds onto first and second and thumps into gear then check gear box pops up and also ticks over a bit uneven shakey a bit is this a cheap fix thanks :) :)
-
new gearbox really, i had this problem with my ar25 so swapped it for an ar35...you need the gearbox ecu codes reading to see whats actually up with it, think its to do with the pressure control solenoid but thats a stab in the dark without going to vx and having it read
alex
-
Agreed get the codes read, you may get lucky just by changing the Autobox oil though.
-
are you absolutely sure it's an LSD you're putting in ?
it's easy to tell - they are the only one with 4-planets. If there are crossed shafts inside the diff when viewed up the driveshaft hole, then you've got LSD.
DO NOT underestimate a GM dealers capability to get it wrong. Getting the wrong oil will permanently knacker the diff. It's not just a case of draining and re-filling. Once that hypoid agent hits the friction plates they're ruined.

yep i think that may be the issue with my LSD thumping when hot due to someone fitting the wrong grade oil or its dam low since police had mine serviced last 20k ago!!
Easy way to tell if an lsd is fitted jack the car up so both rears off the floor & without handbrake on & auto in N spin 1 wheel if both go same way lsd fitted if other goes backwards its standard.
-
no, that's not a reliable test.
You'll find that some Omegas with open diffs do that, while some Omegas with LSD do the opposite. It just depends on how the tolerances stack up inside.
The diff, even though it's LSD still has planet wheels, and if the ramp is clean and the plate stack isn't too sticky then you'll get reverse rotation. Especially with a diff in really good condition.
the only really good way of telling is to pop out a driveshaft and count cross-pins

oh... ive got 3 vehicals with lsds ok 1 is a full detroit locker in my discovery but the omega both spin forward or both reverse & same with the diff in my morris ital using a lsd axel out of a tr7 again both spin forwards or rear but i can see what you mean how a standard diff could mimic an lsd if tight etc but under load will be open, & a slipper lsd with no load would do that clock anti clock test too...
-
an LSD still has planet wheels and the capability of providing reverse rotation whe tested with the wheels off the ground.
The LSD action is initiated by the planets sliding up a ramp and locking the diff.
So....
if the planets spin BEFORE they move up their ramps then you'll get reverse rotation.
If they move up the ramps first ( possible, even with the wheels in the air ) then you'll get the same rotation
in either case, the LSD function can still be working properly.
