Auto box, Servicing it and wave spring

[miller]

Okay it seems like the Oz guys have made leaps and bounds in this deptartment, ive had a read through their thread and its made me want to service my box. Now i need a full flush so it makes sense to do it at the same time.

This is the OzVR4 thread http://ozvr4.com/forums/showthread.php?t=8035

Nick / Richy / Eurospec have any of you chaps done one of these?

Is it literally just the wave spring and the seals? Im presuming by seals they mean the torque converter seal?

Input greatly appreciated?

The seal(s) that Dylan (Eyeballprawn, Thread originator) is referring too is the brake retainer seal. The torque convertor seal is un-touched during this "fix".

I recommend all auto VR4 owners read his thread. It is simply an awesome read and without a doubt, will help a lot of AT VR4 owners undertake the uprating of their wave springs without having to remove the box.

I just read this too.

It looks like a great piece of info and I suspect i've seen part of that wave spring before lol

anyway i can read it without joining oz site??

no I dont think so.

Its free to register though

Am i right in reading that thread through a few times that there are two levels of service, ie just accessing the wave spring with the gearbox still in and then level two removal and pretty much replacing every serviceable item?

I took it as the main wave spring replacement with some "optional extras". Although I didn't read in massive detail, I just took it that i'd need a copy of that guide if I ever looked at doing this job!

To be honest if I was going for this job, i'd want the whole lot done !

Just need to get Gowf primed, and i'll be good to go

You'll have to register, but there is no charge for using the site or any of it's guides, they only ask for donation if you want to use their classified section!!

I have done this procedure and am slowly in the process of documenting it!

It's pretty cheap, but a little more involved than I originally thought. However the transmission stays in the car which is a big plus. There's not much that needs to be replaced, the biggest expense is the liquid gasket goo.

If you have a bit of experience working on cars then don't wait for me to get my act together, the PDF of the gearbox manual is all you need. And if you get stuck just yell for some help. There are a few of us who have done this now.

If your car has low mileage then apart from the wave spring you only need replace the seals (not the torque converter seal though) and maybe the valve body gasket if you damage it in the process.

The job should take you no more than one evening's preparation, and a full day to complete the procedure.

The point of this service is to replace the OEM crappy, weak wave spring with an uprated replacement, fully solid unit. In order to do this, the box does not need to be removed from the car. If your clutches are in good condition, there is no need to replace them.

It is a pretty well know fact that Mitsi should have recalled our auto's after so many failures of the wave spring. When or if the OEM wave spring breaks, it sends pieces of it through the box destroying other crucial parts rendering the box destroyed. If and when this happens, we all know what and how much it costs to fix.

Think of this fix as a precaution. Doing this minor fix now may prevent your auto ever going BOOOOOM!


Edit. Dylan beat me to it!

Wow guys thats brilliant, i am going to order the 'goo' and the wave springs and get on with it. My car is very low mileage so i just want to be on the safe side.

Which i presume are these two items

1 x 2741A007 SPRING,A/T L-R BRAKE WAVE
1 x MD974421 LIQUID GASKET,A/T

Should i also consider doing the torque converter seal aswell? No problems with it currently. Though isnt that a Box out job hmmmmm

[Nutter_John]

Doing the TC does need the box out

[Mark 4]

Well I've got an old box sitting in my shed waiting for a full overhaul. I had hoped to do it over the Xmas break but money is a major problem at the moment so I didn't get around to it. As soon as I have funds I will be ordering a full kit. Will no doubt post on here for some info/guidance when I finally get around to it.

[miller]

Right i have added the Valve body gasket and other seals to the shopping list as per Dylans post on OzVR4

1 x 2741A007 SPRING,A/T L-R BRAKE WAVE
1 x MD974421 LIQUID GASKET,A/T
1 x MD757211 OIL SEAL,A/T 2ND BRAKE RETAINER
6 x MR486844* O-RING,A/T CASE
1 x MD756673* O-RING,A/T CASE
1 x MR486686 GASKET,A/T VALVE BODY
2 x MD760146 SEAL RING,A/T CASE (Optional)
2 x MD760147 SEAL RING,A/T CASE (Optional)

Im presuming the last two seals arent needed if im just aiming at the wave spring replacement?

Im on my way to Chris Variava in Notts now, i just need clarification on exactly which seals i need, as i suspect that list includes everything to complete the whole works, whereas i only need the wave spring and associated seals

Cheers chap! I thought that when i saw it, though i have to apply my 15% discount to that too, which will nearly cancel the VAT off!


I had read that only three of those seals were needed if the wave spring was being replaced on its own.
