So following on from my previous thread I've now bought a good used box and will be fitting it over the weekend.

 

I've got a couple of questions that I can't seem to find the answer to...

 

How much ATF does the box take INCLUDING torque converter?

 

I understand I've got to half fill the torque converter before installation- do I fill it through the front shaft?

 

Are there any other awkward bits that I should be aware of?

 

Cheers

About 8l from empty, but often they aren't fully drained so mine took about 5l (luckily) and showed correct level. Best to buy 6-7 to be safe, but you might not need all of it.

 

Never heard about filling the torque converter and the nissan mech didn't do it with mine, maybe if it is brand new and/or completely drained of any fluid, but buying a used box it will generally have some fluid left in there. (maybe its a good idea though)

 

You have to unplug the loom from the engine bay to take out the box, make sure the loom on the new box is ok as some are not a straight swap. To unbolt the torque converter, you have rotate the engine and unbolt the 4 bolts from the starter hole. Make sure you mark the prop and install it the same way to keep it balanced. Have strong muscles, you won't be able to lift it on your own so best have a friend + jack under it is my advice. Get long extensions to get the top bolts off the bell housing.

 

That's all I can think of off the top of my head. Any other questions welcomed.

Cheers for the reply.

 

Ah right, makes sense with it being a used box.

 

The loom has been cut on the new one, so looks like I'll need to swap all the sensors over.. But you say some are not a straight swap... Will I need to splice in the cut loom to my existing one if that's the case?

 

Yeah I go gym everyday but I'm not feeling lifting that up on my own lol.

 

Thanks again

Can't tell you for sure but I swapped mine for a later box and it looked like the shifter part was slightly different. The loom doesn't simply 'unplug', I think it was the shifter sensor that you had to swap over because the loom is directly attached to it. At least that's what I seen to remember, stand to be corrected.

Answering in the order you asked

 

Add four litres when the box is installed down the dipstick hole. Start the engine and with foot on the brake select all gears and then back to Park, wait a few minutes ( warm up ) and then do the gear selection again and back to park, now replace the dipstick and check the level, add 1/2 litre and check again etc.

 

No real hard bits other than the weight, lots of care has to be taken to stay safe.

 

If the loom has been cut you have some trouble depending if all cables have been cut, if so you cannot just swap the sensors over as some of the cables go direct into the box. This will need the old loom to be grafted into the replacement box, personally I would not have touched a box with cut cables, the seller clearly removed it the wrong way from the doner car.

 

 

Did the box come with its own torque converter ? always good to keep them together, your existing torque converter is most likely contaminated.

Ah no, I bought the box from Nippon autos, is there no a way round it then?

Yes jeff, new box has it's own torque converter.

As Jeff said if that sensor cable is slashed, you got some soldering to do ;)

Ah jeez ! no wonder they cut the cables, they supplied and fitted a replacement engine some years ago to a twin turbo zed, I did a tech on it as it came to us running badly, turned out it was a Non turbo engine they had swapped his old turbo`s and sump to, problem was they left the old non turbo injectors in !!!

 

They did not have a clue, red rusty water in the rad and cables and pipes mixed up all over, snipping the loom on the auto box you bought from them actually means its not fit for purpose, as the box electrical system is so designed to just plug in.

Yeah I wouldn't have thought that would have been their forte tbh, they're a breakers yard so mainly strip parts. The box looks to be in really clean condition though so I've got no reason to doubt them other than the fact someone has stupidly cut the loom.

 

Although I appreciate what you're saying surely it can be connected to the original loom if it's spliced in, a clean job should ensure there aren't any issues from joining the looms together?

I'm pretty annoyed about it tbh, got so much on this weekend I could have done with the box install going smoothly... Never the case though is it lol

Firstly they are there as a specialist breaker, cutting the loom should make the sale void in my mind as they can NOT warranty that box now, which the cynic in me would suggest from prior knowledge of them may of been deliberate, any problem later WILL be attributed to the loom and your splicing in ..... fact.

 

Personally I would ring them up and ask why the loom was cut and how they expect you to fit it? also what effect this will have on warranty if you splice the old loom in, ask for the answer by e-mail. No doubt they charged you premium rate for the box ? just feels to me like you got half a deal.

 

If you still want to proceed with it though, splicing in the loom is very possible and have actually done this when a customer presented us with a box for his zed minus the loom! mostly the cables are coloured or size appropriate, but you will also find many black ones in there, careful tracing and double checking will be required, lets hope your loom is not the problem with your existing gearbox!

 

Good luck feller

Yeah I completely agree Jeff, he was really sorry about it and has given me a partial refund tbf. He said there's no way it should have been cut but took my word for it.

 

He says it still has a 3 month warranty too so because I've got to get it done I'm trying to make the best of a bad situation mate.

 

I'd rather not have to splice obviously but atleast if it's done properly-I'll use heatshrink- it's going to be working properly... As long as the looms not the culprit... lol.

 

Thanks for your help Jeff, hopefully I'll be able to update some good news by the end of the weekend.

 

Cheers
