Well Hello There Fellow Hivers And Technicians

As in most of my previous posts that we have an immense heat wave or something of the sorts passing over us, and yes I'm still dying of the heat. It might be that I started melting now.

Anyways, the heat. However bad it may be it's somewhat great for business, atleast so in my trade. You see the thing is that motor vehicle's generate a lot of heat and therefore your cooling systems in the vehicle must be able to work on full capacity and full load at any moment.

Other wise fry.

Since I started working on automobiles I noticed a trend, there is always a trend going about. The one week we'll get only fords the next week we only get Audi's. And it always changes. And every year when winter approaches there is a nasty decline in the number of automatic transmission coming in for repairs, but when the heat comes again you can notice the numbers rising again. Today we booked in 4 Audi's and all of them with automatic transmissions.

Why does this happen?

Well they break of course, the reasons can be plenty, such as improper cooling, low on oil etc. It can even be normal wear and tear, but you see all of them are bound to fail at some point and with the heat striking all of a sudden it rips that last cord that kept the transmission running right out of under it.

That's where we come into play.

The Burned Up Quick Fix

Okay I know this isn't one of those automatic transmissions yes. But it serves nicely as a reference as to how hot it really is. These things are quite resilient too be honest, however they aren't bullet proof. They don't tend to break into an irreparable state. Usually it's a bearing or two that collapses from oil starvation.

I have to say it looks a lot worse than it actually is, it might need a gear replacement here or there but it's nothing major. The grime and burnt oil looks hectic to be honest.

What would you say? How does it look? Like a colossal mess right?

Popping this open well... I know I said it's not that bad, but the more I look at the photos I think how can a person end up doing this to a car? Ever?? It blows my mind! Look at all that dirt and grime sticking to the inside of the casing.

Both the parts and the casings needs a good thorough wash with paraffin before any real damage assessment can begin. As a stroke of luck I would say we are glad it didn't actually burn all the way through. The owner of course want a cheap fix and he will get just that, well the transmission will hold but the gears would be a little noisy because of the lack of oil that put him in this situation.

I'll be honest and say the funniest thing of all is the fact that the clients wants to tell us it can't be something big or it can't be this or that. When in reality they drove their transmissions into the ground, can you believe.

This transmission must have given problems for months on end before actually giving in or creating a insanely loud rumble from all the buggered bearings. So bringing it in only now means that the driver is either incompetent or unwilling to better the situation.

The bearing cages are even melted away, now I can say with certainty that it got very hot on those rollers, certainly not the worst I've experienced, not by a long shot.. But I do wonder what it would have sounded like if it was driven.

Laughs Laughs

Sitting here typing all of this I somehow drifted away thinking of all the dirty transmissions I have opened in my life and this one is most likely in the top 10, perhaps 20. It's a ganky nasty smelling thing to open.

If I could best describe the smell I'd say it smells like a very metallic burnt smell. Although it is hectic for some people I found that I quite like the smell, I have no clue as to why.

Well I'm basically done over here, all that's left is to push the last of those gears of on the mainshaft lying in the middle of the bunch in the photo.

They press off fairly easy, perhaps the easiest transmission to do a teardown on, you just put the main shaft in a press with a long dolly that is able to push and fit through all of the gears and with one press you can remove all the gears. No need to remove cir-clips or locking pins anywhere.

Trust there isn't a lot of them around.
