New D2 TD5 Member to go with TDi300

The ultimate Christmas gift Lemo, just read through all the functionality and wow, thinking it may be a mandatory buy, in fact sure it is.

Raised a few questions, why oh why do I read!!

I'm a boy and there was the option of more power.... Well I don't want a road racer but a little more is always nice, in fact I am more a torque guy, don't want to have to rev a diesel for the ultimate power, just oodles of low down torque. Good question, why do I have the 300 TDi and TD5 then.

Have the 4hp22 in my BMW635i which was purchased for a conversion to LT1, the motor was too good so left it in, but, in the time I was researching the conversion the maximum torque for the gearbox was 350-380 Nm from memory (the LT1 made way too much for a dependable marriage)

Remapping | Broad Lane Land Rovers

seems to be showing torque numbers at the upper reaches of the dependable range just in level 1 let alone 2 and the next steps, are peeps using the Storm and other upgrades experiencing failures of the auto or has the box been upgraded or I am just mistaken????

Recent history of a 2004 td5 I came across was TRS re map at 200 000ks for more towing power ..then at 250 000ks auto fail + full auto rebuild costing 6k...then within weeks engine fail with massive blow by. ..resulting in car being auctioed for ...b all dollars.

Maybe re map at high ks is not a good idea particularly given the very un-german auto craps itself naturally @250 000ks...well mine did😐

Were there signs before the demise of the transmission, jolt on change or excessive slur? Read a bit about the flex plate and the debris completing the destruction, would this be a mandatory c/o at some time, must say not exactly sure what this flex plate does in relation to the transmission.

Not sure about that one but mine developed a judder switching to o drive.. it may have kept going but needed to change b 4 the big trip.

Same guy with the one cited had another d2a that broke a flex plate ear off completely resulting in vibrations then total failure. Why he bought another one after losing a truck load on the first one is beyond me🙄

But now he's got a jeep v6 😆

I check my hd flex plate and torque converter mounting points regularily..using a hoist .. peeping thru the round hole. Any sign of cracking and it's out with the box b 4 it becomes catastrophic.

Wish I'd bought a manual but they are rare as hen's teeth.

so this flex plate is the main concern?

Can be!

It's a bit hit and miss.
The originals weren't too bad. Some broke and some lasted fine.
What's happened now tho, is that replacement flex plates are the known weak issue.
There's a LR specific parts website that even warns against buying and using them!
That is, the current supply of LR branded flex plates.
Can't remember who, but strong recollection of the new guy in Bayswater(British 4WD or something).
He still sells them, even tho he has the warning on the web page for the flex plate.

The other flex plate issue for both the D1 and D2, is the V8 type is notorious for breaking around the flywheel mount.
TD5 is notorious for breaking at the vertices of the triangle.
(Td5 is triangular shaped, V8 is circular)

So the issue is(for you) the history of the vehicle. Has it had the trans done? has it had the torque converter done? if so, did they also change the flex plate? if not, did they do the bolts up to the correct torque? did they stress the plate in any way prior to fitting?

etc. etc.

We think brother Td5 still had original flex plate. His torque converter started playing up a while back(maybe earlier last year now).
Started to vibrate first, then much later I noted it was unlocking far too easily, hence slipping. That is, it'd lock, but any amount of push on the pedal, no matter how small and it'd slip/unlock.
So he got it fixed.
Torque converter from an auto place in Thomastown, and as it was only around the corner from LRA, got a heavy duty flex plate from LRA as well.
Worked out that the flex plate from LRA was going to end up at about the same cost as importing one from Ashcrofts .. give or take a few $s.
For the sake of having it in his hands same day from LRA .. the $ difference was insignificant.

torque converter HD cost about $400-ish I think too. (can't recall their company name, but they famous for their Dominator branded TCs)

Have to remember to ask brother what he's done with his old flex plate too.

with the Zf I have always regarded as a very smooth box so any irritation would be noticeable early on I would hope, the triangular shape is most unusual, there is no doubt some explanation for that, found a great youtube on the inspection hole, but this was now 2 hours ago.

Seeing pictures of the others I had always known this as the starter plate, just what did i know!!
