G'day,
Spent quite literally the entire day and some night putting this gearbox in. so far i am having a little but of trouble with the 3rd and 4th linkage bracket fouling on the tunnel. I am not quite sure what to do here and wondering if i can rectify this by heating it up and bending it in. I tried to invert it but it fouls on the bolts so its a no go. Responses greatly appreciated, have to have it finished tomorrow.
Cheers

I'll go out on a limb and say you're doing it wrong
Its fitted before...so what have you done to change that

Wrong selector levers on the gearbox to suit an LC I suspect, and possibly wrong shift rods also.
As Datto said, some pics would help.

If had something to take a picture i would have but having broken two iphones and a camera i am out of luck. Best way to describe it is the selector bracket where the rod screws on (gearbox side) scrapes on the side of the transmission tunnel. I already went through the M21 thread however hanra is having trouble with the rods fouling on each other, whilst my 3rd and 4th selector rod fouls on the trans tunnel. X member is on the right way, wont line up the other way round.
Dave i'm thinking it may be wrong also however do the length of brackets differ at all?

LC/LJ 3/4 gear selector lever on gearbox (when compared to Brad's LH) is longer and offsets slightly in towards the gearbox.
The 3/4 shift rod comes up from underneath the 1/2 gear selector , not over the top like in the LH Torana.
The 3/4 shift rod then connects to the g/box selector lever via a metal trunnion inserted into the hole in the lever, bit hard to describe really.
Will post up a pic from the parts catalogue.

I would have thought the Aussie M20/M21/M22 shifter rods and selector levers from other model Holdens would work on the LC/LJ but maybe not.
Anyway here are some pics of the original LC/LJ parts but I doubt getting them will be easy.

I see, mine is entirely different. It must in fact be LH as my 3/4 selector runs over the top of the 1/2 selector, rather than along side... but then again in brad's thread he rectified the issue by running along side as depicted in the lc/j catalogue diagram

Jacob, Brads linkages are how an LH should be. They are not the same as LC/LJ.
On a different note, which gearbox crossmember are you using? The one that was with the Trimatic or did you get the proper manual box crossmember?
Just thinking have you fitted the spacers that sit between the chassis rails and the crossmember.
In other words your g/box may be sitting too high causing the linkage to foul on the transmission tunnel.

Hi Jacob
I'm using the trimatic cross member in my LC without the rubber insulators. I have a lot of room around the box and shifter rods.
I will head out to the shed and get some pics of my shifter set up
Back soon
Regards Simon

Yeah they definitely dont look the same. I didn't think there was a difference in crossmembers as no one has ever mentioned it when discussion a manual conversion and this may be a problem. What i might do is check out the crossmember and see what i can do, i dont have spacers and this may very well be my solution as i would like the avoid 'persuading' the trans tunnel.

Hi Jacob,
Box is out of the car at the moment, but this is as it was in the car,Linkages look same as Brad's
Cross member I used was the trimatic one, with the rubber insulators removed, mount is standard Holden

Does your cross member look same as mine Jacob?
I don't run any spacers on mine at the moment. I have done previously and to be honest, forgot and left them out last time I had to change the clutch.

You don't have the plate that the mount bolts go through UNDER the cross member between the cross member and the mount?
I have seen this before and it raises the box

I have been through this. No spacer between gearbox mount and crossmember, spacers between crossmember and body.

put the spacer through crossmember and body, helped a little but not as much as i want. i feel that when the engine revs, the links will foul on the tunnel. what spacer is there between crossmember and bearbox mount? i dont recall there being one when i pulled it out?
simon, i think the rod is different, brackets the same. the lh lx appears to bend upwards, and lc lj downwards. i guess i could simply modify it but that will be another day as ive lost my time on the hoist.
had a lot of trouble today, couldnt get the brake pedal out as the pushrod for the brake booster would not lever off the brake pivot. will maybe unbolt it from the other side and get it in better. as for the rat trap had a bit of trouble as i have nothing to mount the relay support bracket to. im guessing it is mounted to the bell housing however there is no bracket. will perhaps make something up

Hi Jacob
There is a thick plate that the gear box mount bolts go through, goes under the cross member. You may not even have one.
Sounds like the conversion is being a pain, but stick with it.
Could always mount the selectors on the box up side down and have a reverse H pattern, not ideal though.

There is bracket bolts to bell housing for rat trap relay Takes two bolts to connect to bell housing
The LC does appear to be different to LH! But the pics I posted look same as Brad's LH , they fit fine in my LC, so there must be another cause.
As craiga states no spacer between mount and cross member , sounds like you don't have that part and spacer between cross member and body each side of cross member, sounds like y have that. I don't run these and still have clearance.
Are engine mounts sitting correctly? Just looking for a reason that the motor may be too high,

Is an LC floor - specially the gearbox hump, different to an LJ?
As I said you need LJ style with no spacer between gearbox mount and spacers at crossmember to body BUT even then my selector levers are too close so I made some additional crossmember to body spacers and dropped the gearbox lower. All fixed.

Can you borrow a camera an get some pics ?
You might have to make up spacers to get it going for between cross member and body.
Did previous owner have a manual it it ever?

LC/LJ floor pans are identical.
