You're all wrong.... If it's a ZF5hp24 then it's the forward clutch housing.The snap ring groove breaks as it's a stress riser.The circlip moves out of the groove and the clutches don't apply properly.Eventually the clutches move so far that the piston comes out of it's apply area and nicks a piece of rubber off the side of it..Jaguars have the same problem with the same trans.ID the box from the tag at the side. It's a trans out job i'm afraid.

I'll have another go at the trans fluid level, and follow your advice. I REALLY hope it's that! I took out the selector switch and cleaned it today, but I haven't had the chance to test drive it since. It wasn't all that dirty but there was gunge on the contacts. If it's the torque converter or anything else major, then the car's future is looking very uncertain. I can't be doing major work on what's supposed to be my daily whilst my project gathers (more) dust.

HOWEVER (and maybe I should have mentioned this before ) when I undid the small sump, there was a small piece of an orange plastic ring sat in the sump. Looking up into the workings I could see the rest of it (loose) but couldn't retrieve it because the hole was too small. To be honest I figured that I couldn't do anything about it so removed the loose bit from the sump and carried on. As that is at the front of the gearbox... could this be a symptom of what you describe? I feel stupid for having not mentioned this before.

Sorry I didn't give everyone the full picture earlier, I didn't think the two were related as I figured it had come from the overdrive part. Well, this leaves me in a bit of a pickle as MOT and Tax is due very soon... Thankyou everyone for your help, this is why I *heart* retro-rides!

If you'd have mentioned it you'd have saved me writing.. ;D No chance of it lasting a couple of thousand miles.Already it'll be churning up the overdrive clutch housing.You might be able to weigh it in soon..

Norm Then obviously I need glasses... ;D Thanks,although i've already run 7.4 at 197mph outside of Street eliminator and 7.67 on radials and pump gas.That 8.1 was spinning the tyres all the way down the track.It was the first time anyone in Europe has run 190mph in competition on pump gas that's all..

I said buy a more exciting and reliable drivetrain. I quite like BMWs as machinery. It's the typical new car buyers drawn to them that ruin the brand.

It's the typical new car buyers drawn to them that ruin the brand. Fair enough, I know what you mean. It was the General Motors component that failed though... ;D I'm leaning towards swapping the trans, if I can pick one up very cheap. The car will break for a fair amount but I quite like it (I don't let the Benz know that), and was doing a grand job of being a daily until this diagnosis.

Oh yeah. The newer GM ATs are junque. They're tuned for maximum mileage.
Dude, I'm all about TH400 ATs if you're going to get an AT stuck in.
The ZF ATs are a bazillion times worse than the GMs, even the new GM ATs. I don't think ZF in that era ever fully figured out how to build one.

To be honest, auto boxes of any kind give me the fear. I'll look into a manual gearbox swap too, although I don't fancy swapping flywheels etc., and it might send HAL 9000 a bit crazy...
"Just gonna put a manual gearbox in instead" "I can't let you do that, Dave..."
Gimme a carb, stick-shift and rust any day. ;D

This is a bit of bad news It's a nice car, would be a shame to bust it for parts but I know what you mean about the time bieng spent on it, and I suppose it depends how much a new box would be aswell...... Wonder what it would fetch on Ebay with a faulty gearbox? Might be best to punt it on while the problem isn't too bad?

Yeah I'm mulling it over at the moment. The engines seem to fetch decent coin, and the fuel pumps are sought after too as they're big money to replace and they do fail. The wheels would net me some cash. But the rest of it I doubt I could shift on and would end up being weighed. Plus there's the time it'll take to break it, and getting a replacement daily with the proceeds... and like you say, it's a nice car and it'd be a shame to break it. I hate selling cars on eBay - it's expensive and you get a lot of messers, but it'd be the best place to sell it with a duff gearbox I think. I'll see what turns up parts-wise. There's also the fact that I'll have to do the sump gaskets, filter and ATF AGAIN after I've replaced the box! Although I could probably re-use the filter as I've only done 20 miles or so... Argh, cars eh?! ;D
