Haha, My mate actually asked me how much of a job it would be to get the gearbox sorted in that. I really dont have that kinda money to spend at the moment. Im just gonna manual convert mine and new diff, Saves having to swap all my parts over.

Thanks Simon, The guy told me it has 40 teeth.. Guessing he miss counted and its 39, Meaning its a 4.8:1 Lsd.. Maybe i should get that and find a 4.8 for the front aswel? or Swap my pinion in and put washers in or what ever you do to make it really tight.

Edit: just picked up new LSD diff for $100. But it is from a petrol terrano.. do they still fit?

Yea, just ratio different (maybe same if you lucky- have a count up) as long as same type of diff (ie not the navara c200)

[will i am]

just swap ya pinion gear(i think thats what it is called) over and you should get the rite ratio

[u13turbo]

Ok sweet as I'll look into it, Gonna be a pain swapping gear over but owell.

[u13turbo]

With the gearbox, Ive just left the bung out for the past 2ish weeks, so its well drained, My plan is to chuck new oil in, go for a good drive, then drain and refill with a second lot of new oil, Will it be ok?? Also Straight after it happened, in drive it would start in 2nd, not first, if i put into 1 on the selector it would go into first, Is that a terminal problem? or should new oil sort it?

cant wait till its going again, Been awhile since Ive been 4wding!

cheers

[u13turbo]

I got a diff from a v6 petrol terrano, its got 37 teeth on the pinion wheel, Can anyone tell me what ratio that will be? also i still have the bung out of the gearbox, Should it be allgood to whack some new oil in, take for a good run, then drain and put another new lot in?
Cheers

[DieselBoy]

Your half way there if you have the crown wheel tooth count, now all you gotta do is count the teeth on the pinion and you can work it out.

Do they not teach that sorta stuff at school these days??

Post the pinion teeth count and we'll tell ya

You've still got auto trans? draining trans only drains about 1/2 the fluid out, there's still lots caught in torque convertor etc.
Fill it up again, start it up and check what condition fluid looks like before you go driving. And take it real easy on the trans with ANY fluid contamination- it'll die easy. The heat developed inside will get rid of the last bits of moisture, but keep flushing to get rid of most of it.
You can also pop off a trans-cooler pipe at radiator and start engine to pump out fluid (don't run it dry tho). May be easier than climbing underneath each time..
See how ya go, but start saving for the manual conversion

I would fully put a manual in now instead of wasting money on new fluid. Only problem is i think due to the water getting everywere its probably best to get it running and then upgrade to an ln106.

Thanks for the info about the auto box. I drove it home the night it happened about 3kms, hopefully that hasnt done any damage?

[yeti]

yep them torque converters hold a bit......clean oil cooler as well plus lines...



first drowning we pumped 34 litres of that red shit through the trans...think i paid 130 +gst for 20 liters, so gets up there......
dont for get ya diffs.....

shit.. Is it actually going to work just by filling, running, then refilling with second batch of oil? by the looks of it, it will still be really contaminated..

And yeah i've drained diffs ready for new oil too.

[meatc]

No refilling it wont get rid of the contamination. You either need to pull the box and drain the torque convertor or the best bet is get it pumped by a trans shop. You should do the filter inside to.

Also be aware that the linnings in the clutch packs is water based so they will come apart eventually if the water is left in. The heat will prob damage it first.

what meatc said... pumped through, thats what we did....was just drain first time and started shifting bad ,shut it down on side of road... towed to mates and pumped it.....went well untill 2nd swim a few months back...didnt bother this time around and just put another trans in..

Alright i might just get a new trans. Ill look today and see if all the lights etc are working, if they are i might consider the manual conversion.

Thanks for the advice guys, appreciate it.

[will i am]

manual convert it. less oil to change after you go swimming and it will still work haha. what parts do ya need for ya conversion?

Havnt got enough for that at the moment. my plan is to save up for a ln106 now so not too worried about doing it.
To manual it i still need to rebuild my gearbox, and all manual conversion parts, Easily 1k+ and the new auto is only $500.

Yesterday i got powersteering flushed and sorted, rear diff new oil, engine new oil and running, need rattle gun to get front diff bung out :/ lights are working correctly, head unit that was under water for a good half an hour works! unfortunately my amp doesnt..
Only problem now is getting the box out on the ground by myself with a bottle jack....

[u13turbo]

Bought a 2T trolley jack for $99, got everything removed from around the gearbox and started prying it apart from the motor, just abit sketchy because the jack is holding the back, but nothing for the front.... not sure what I should do there, and im doing all of this on the side of the road in Rangiora...

[Sketchy_Racer]

Hey mate, I did it like you with a trolley jack, I built a wooden frame that locked into the cross member and held the jack in place which let me lower it down. With gearboxes, you need to slide it back from the motor then lower out at an angle (well with the manual boxes) so you will have at tough time just holding the back of it.

The box will be 100KG plus so don's do anything silly like try and catch it if you drop it!

Have you got the truck up on ramps?

Hey. i could try use a small strop and ratchet to basically tie the box to the jack, the way i tried today wasnt the best as the road is really rough and the jack doesnt really want to move backwards, Ill try get a big piece of wood that it can roll on. I have the front jacked up on axle stands(so i could remove torsions) And yeah i definitely wont be trying to catch it! its only gonna go to scrap anyway haha.

Cheers

[FORGE1]

Hey mate,

when ever I take a gearbox out at home I use a trolly jack on the back of the box and 1 axle stand at the front and it seems to slip out onto the axle stand while lowering on the trolly jack.

I try and get it to slip off the trolly jack and slide down the jack while lifting off the axle stand (to get it to the ground easily).

Hope it helps I have done this on my bighorn a few times and a Hilux surf.

[mud_slinger]

why are you doing it on the side of the road? do you need a tow or something?

Ok sweet as might try something like that, I will get it eventually haha.

Nah just doing it outside my brothers flat, parents had enough of cars in pieces around our house lol..

[slide]

Have you thought of unbolting transfer case off, taking that out b4 trans?
Then you'd have two 50kg bits instead of trying to manouvre out a 100kg lump...

[will i am]

put some wood under the front off the gearbox so it slides onto it. instead off droping onto the ground.

[DieselBoy]

Two tie downs strung between the chassis rails works too when your out on the trail and don't have a jack.

Works especially well for putting the box back in, as you just tighten the tie downs and they lift the box up

Its allgood, boss let me use hoist tonight, got gearbox out, new one in, just got shit too hook up tomorrow, love perks of the job Thanks for advice though! cheers

[passengerpete]

did ya need to change the drive shaft ? is auto manual the same ? will be interesting if ya notice a performance increase or not.

that's nice off him..could have offered a bit earlier eh.....hope all gos well for test drive..ya done well man......

Just putting a new auto in man, and im 99% sure manual and auto shafts are different lengths. But i should notice performance increase, my old one was slipping, and the new one looked as though the torque converter was brand new! so possibly recon'd not so long ago.
