right the leak is now getting to the point where its costing me a small fortune in ATF. (188mile and then it need just under 3ltrs.)

Right we are looking at replacing the torque converter seal. one snag. how do you get the bl00dy thing off with out damaging anything???

i looked at the old one and couldnt get it to bude. your advice would be great. it has a twist thread on it.

`Haven`t done a miggy-box T.C oil seal Marie...I`ve done a few on American auto-boxes though and I`d thought they`d be similar.

The lip-seal is normally positioned using a 'drift' (as you would for a bearing)...I`ve used a large 'socket' as a drift for that job.

Removing the lip seal (if it`s the drifted in place type) could be achieved using a slide-hammer or even a screwdriver held at a shallow angle as a lever; being careful not to scratch or damage the aluminium transmission housing.

Maybe an 'expert' will be along soon to confirm the lip-seal is either drifted or screwed in place.  

Edit:
Just looked at http://www.omegaowners.com/forum/YaBB.pl?num=1183142571

Does the oil seal fit in that (shown-empty) recess in the aluminium bellhousing around the mainshaft in the second picture?

[Kevin Wood]

It does look like there's a space for an oil seal in the bellhousing as Debs says. However, there must be one in the torque converter itself to seal where the shaft enters the torque converter. I'd have thought it would be this seal that would have been more likely to be damaged during gearbox replacement. :-/

Doesn`t the T.C have a spigot protruding from it`s torus-body with splines on it`s inside and a smooth outer-surface for that oil lip-seal to run against?.....all of the ones I`ve seen before did.

[Marie]

Right as per that guide. the second picture you can see the seal. its the metal ring with 3 screw holes in it.

there is nothing protuding from it to get the bl00dy thing off. i think its goig to have to be tapped off. it defo has a screw thread.

Cheers kevin. i need to get this fixed asap.

Their are several gearbox specialists in fareham that might be able to help.

i could get the box off and take it to them to replace the seal for me. (maybe dependent on their cost, i have a new seal already. i might call them monday.) and its getting the box to them as if i take it off i have no car to get the box to them. i am going to have to source a bigger jack and a torque wrench too before i take the box off)

[Kevin Wood]

Ahh, OK. Have never looked that closely at one, TBH. You're probably right, Debs. I can imagine the seal could have been damaged pretty easily when offering up the torque converter in that case.

James fitted the TC and said that it went in ok. so we recon it was damage before and we never noticed it.   ether way its got to come off!

[Kevin Wood]

It looks like the seal just presses into the recess in the bell housing and is secured with the 3 screws? Are you saying there's a large thread in the bell housing that it screws into?

yep there is. i didnt notice it until i got my hands on the new one. its not that large a thread its a relatively small thread when you look at it. but i think i might have to wd40 it or spray that stuff we used at your on it.

Kevin

That`s normally why you have to pre-mount the tranny and torque-converter together (off the car), before jacking the 'whole' into place on the flexplate/bellhousing.

[Debs.]

Two possibilities, marie:
Is it the 'correct' seal for your transmission?......is the 'thread' really a thread or perhaps 'rubber-ribbing' to keep pressure on the seal`s outer face?

[sassanach]

the seal just press fits into the bellhousing and is secured by three screws

[justme]

I assume with a retaining plate, or is there a flange on the seal for the screws.?

Marie you may wish to consider carefully using 2 self tapping screws into the seal in order to lever it out, or also you could knock up a sort of u shaped plate to allow you to lever onto the side of the casing. This technique is used to remove crankshft seals.

OK not good looks and sounds like its going to be a b*tch to get off. i might try it on the old one first.
