View Full Version : How do you tell if it is still your gearbox

This may sound a silly question but can you identify a gearbox back to a vehicle? Reason being I just had the auto rebuilt and it has been painted in crappy silverfrost and the dirt wasn't even cleaned off the extension housing. Ok it is filthy under there so no big deal then I noticed the sump plug is not the nut type any more but an allen key. Again no big deal, then I noticed that the dip stick knob has a couple of cuts on it so it isn't the original. Add this all up and I started to think maybe this isn't my original box. May be its from a wreck. I have heard of this happening to people before so is there anyway of telling where a box comes from?

Serial number?
Sounds like it's been swapped out though.

the boxes have serial numbers on them. on a couple of my sereis rovers all the numbers were recorded in the original owners warrenty paperwork
Didnt you write it down before you sent the box in for work?
If its a rebuilt box (allegedly) and it comes back dirty Id be making noise. 51Jay nearly got caught out with it but a lucky break and a bit of a mishap caused the problem to be identified. the "story" goes that itwas just a case of a newbie mechanic accidentally mixing up some paper work/job tags.

No didn't write down as at the time we didn't know it was going to need a rebuild.
The dirt is where they havn;t cleaned the extension to the trensfer case then sprayed the whole thing. Its just slack. There was nothing wrong with the way the box looked before. Its aloy they don't rust!
Do some Disco's have allen key sump plugs?
The box goes fine. Holds first a bit long when cold but its only done 100km.
I have to take it back anyway as they didn't connect the reversing lights or the diff lock light. The diff lock was in and I didn't notice for 20km. I also noticed the heat shield on the passanger transfere mount hasn't been fitted correctly.

That may be a problem, especially if it holds through to redline before changing. Nothing thats going to kill anything though.

given that you basically want a surgically clean environment when you rebuild an auto box due to the effect of contaminants blocking galleries or valves Id be suspect of anyone who didnt steam clean the whole casing (tcase included if fitted) prior to pulling it apart yet alone putting it back together dirty.
ok surgically clean might be overkill.

I think you should be able to contact Land Rover with your vin and they should be able to give you the rest of the serial numbers.
Well, they do it for ignition/door key codes.

my series one is all matching numbers apart from the donk is a 2.25 however the dirt and crap on yours in a concern have a good look around and take some pics. however most places that advertise reco will be on an exchange basis so they pick up the trans and fit it for you the customer and return your ****ed unit to who ever does there transmissions

The bell housing and body are clean its just the extension to the transfer case that has had paint over the dirt. The transfer case is as dirty as it was before. I will have to have a good look under it tonight. This morning it was holding first till about 3200rpm which is a bit annoying when you are around the suburbs. I will have to check the RAV to see whats normal. The shop was neat and tidy. I believe they rebuild in house and send the torque convertors away to be split and rebuilt.
Thanks Rob

it may well be your box, but they probably only fixed the box, so it would not be unusual for them to not clean the transfer case as you are getting charged for that, and the last thing they want is for you to complain about the cost and not pay.
as for holding gears, if it's in a v8 disco, it should hang on in 2nd or third to about 7000 rpm with your foot firmly pushed thru the floor, i have no idea about kero engines though.

I thought LR microcat listed the other build numbers once you entered the VIN, but I can't seem to find the CD here, lot's of stuff in boxes.
If I took my V8 to 7G it would fix the hail dents....

AFAIR 1-2 change on a ZF 4HP22in a V8 3.9 is 4800 RPM, and 2-3 is 5400RPM with kickdown engaged ie WOT.
All V8s are limited to below approx 6000RPM deliberately by Land rover by the use of lifters that pump up at about 5800-6000RPM.

But mines a TDI:p
Had enough of V8's after 15 years. Somehow I still manage to have one at the side of the house though:angel:
I didn't get time to check the RAV CD last night I think the TDI shift points would be much lower than the V8. the Tdi only revs to about 4000rpm

Sorry I was just addressing the 7000RPM fantasmagorical V8.
Yes the diesel shift points would be much lower, and if it is hanging in first the problem is almost certainly the governor at the back of the transmission sticking, which means they did not renew it .
I am assuming a 4HP22 with a kickdown cable not an electronic.
Have a look at Ashcroft's site.

The electronic does the same.

Hi,
if it's holding 1st gear when cold first thing in the morning, then once shifted it's fine all day this is the govenor valve sticking, if you are having to rev it hard to get it to shift up every time then the kickdown cable is too tight,
if you want to check the box code :
if it's the early 'non fly by wire' engine the box code should be 1043 010 744
if the later 'fly by wire' engine this should be 1043 010 748
this is the second number down on the ID plate on the left hand side,

Thanks Dave, I havn't had time to get the Disco back to the shop yet. When I told them they said that they had an additive to solve the problem and to drop in back. I assume the govenor valve is an internal part which would require a strip down again?

Seems to me that if your mechanic is solving your problems with additives you've found your problem.:twisted:

Agreed
unless hes reccomending it as a "keep you out of trouble for now but it will still want proper attention shortly" fix if you desperately need the vehicle to last a couple more weeks before you lay it up.
the addatives that fix stuff like seals fix problems short term but make them worse when they fail again (and they almost always do) OR at the minimum make life harder when you goto do the proper repair job.
