The RS6 project including 5HP24 A transmission rebuild SOLD

[RS2]

that's some impressive job you're doing there! Thanks for sharing it with us!
Regarding the oil filter, did you order an original one using the p/n from ETKA or is it a standard one for a regular 5hp24? i have changed twice so far the oil and filter on my gearbox and always have ordered the original filter for the RS6, so i didn't bother to measure them but now you've made me having doubts....did you check before taking the gearbox apart what was the oil temperature it was running at? If it was slipping the temperature should've been higher and you should see some improvement after the rebuild. I know i did on mine after i changed the Torque Converter, about 10C lower when cruising on the highway....

I didn't take any notes of oil temps or anything else before pulling the trans out. Sorry.

The filter came with the other parts from Chester Transmissions. It's not a ZF part. I expect that it's a standard 5HP24 but Mark did talk about the different lengths of tube and said that he would be sending me the longer one and that I had to measure it and possibly shorten accordingly.

After cruising around in 5th gear for a week... I'm hoping to get much better mpg

But then... I'll probably be playing with it also so maybe not

This should be a sticky.

Agreed, it's not everyday someone goes into the guts of these cars gearboxes and shows it on the internet. So big thumbs up from me, makes me much more inclined to have a go myself. The removal of the gearbox didn't worry me too much, but the intricacies of a gearbox internals definitly did!

There is a definite lack of detail about these cars compared to other marques, maybe knowledge is power/moneymaking potential and all that

That's a real worry - I'm not as mechanically savvy as some of you guys, but am I right in guessing that the filter with the longer pick up could lead to starvation of fluid for the 'box?

Yes, you could easily kill an auto transmission like this

MG

[Shoppinit]

Yes, it happens a LOT.

So we know the cause and who makes them...$$$$$$

[RS2]

I've made a start on putting it all back in today.

I've spent a lot of time fixing as many of the issues that I can only do with the engine out.

These include the secondary air system - new pump and bank 1 valve
Water pump leaking
Sheared off bolt in gearbox mount
OS engine mount
Lots of other small details which seem to take an endless amount of time!

Anywhoo... a small photo of the lump going back together.

I hope to have it back in the car tomorrow but I'm not sure if I have enough time to finish it this weekend.

What would it take to dry sump that bsatard? I assume you could keep the upper baffled sump but bin the lower sump for a better oil pump and closed circuit? Only if you were putting it into something else, natch...

[RS2]

Not much tbh.

A sump plate with a couple of ports for large diameter oil lines, a pump, a tank and lots of oil lines.

I haven't heard anyone talk of oil surge issues with these engines but then they're usually fitted into fairly heavy Audi cars so you can't really get that many Gs cornering.

If you were to put it into something like an Ultima (like the one at MRC) then it might be worth looking into.

MG

[bam_bam]

Yeah, the Ultima (MRC) was exactly the package I was thinking about, then my mind wandered to the Gumpert and I figured that HAD to have a dry sump.

[RS2]

Well after a full on session of working from 9am until 5am the following morning (tell me again why I do this?!) she's back together and running.

As with many other things, the work took a lot longer than expected but I did take the time to fix lots of things while it was apart.

The water pump change ended up adding many hours as the last time it was fitted, the bolts were not fitted with copper grease. As a result, two of the bolts refused to come out. I did manage to get them moving but only a small amount before they locked up solid again. I must've spent over 30 minutes on each bolt just working them to try to get them out without them shearing off but it wasn't to be. I had to drill out both. NOT FUN!

Anyway, that's back together and working without leaks now

It was very nice to have the engine and transmissions listing 'No faults stored'

I haven't had a chance to drive it yet (other than manouvre it around inside the workshop). I need to get it on the 4 post ramp to tighten up the suspension links etc while it's sitting at normal ride height and then a test drive is on

MG

[RS2]

It drives spot on

I think with managing to align the front subframe with the original holes etc (will upload photos), I've managed to keep the alignment spot on as it drives exactly as before.

The parts bill for the transmission came to just over £150.00 plus many many hours

MG

[Shoppinit]

Yay! Good job.

Probably better off getting an alignment done anyway, before you realise you've scrubbed your tyres.

Now, how much are you going to charge to do our transmissions?

[RS2]

Yeah I'll stick it on the 4 wheel alignment later just to check.

Lol re rebuilds... no thanks. I hung up the spanners as a job a while ago. I've no interest in going back to doing it full time.
