Today I dragged my dead transmission out from under Swift #1. When I was staring at the remains, the origin of it's sudden terminal failure became very clear to me. I had previously and incorrectly assumed my vehicle had a leaking crankshaft seal. My vehicle was certainly leaking oil, but it wasn't engine oil. It was gear oil. Due to some internal failure (which I'm still investigating), some part of the transmission's internal parts knawed a hole through the inside of the transmission case into the bellhousing. When a transmission is at the state that its chewing on it's case, it's already a clear sign that it's dying. However once the bellhousing has been breached, the transmission will bleed it's life blood - gear oil, and its demise will suddenly be very soon.
Here's a picture of the carnage, those light colored specs are aluminum shavings:

I want your transmission failure horror stories. If your tranny has died, post it here with as many details as you can. I feel the whole Swift tranny failure issue has been under researched, and the more light we can shed on it the better.

Its called over driving, and a very poor tranny for what most people want. And poor maintance.

People drive these cars like they have a Munchie M22 in them. I will call the trannies a sprint tranny, do not like burn outs, either from turbo'd overpower, high rpm drops, driving in rain, or mud. Spinning 1 tire is WAY worse then spinning 2. The lack of an affordable LSD is big down side.
Guys installing big and heavy clutches in their cars. Shortens life of tranny alot.

For long life, change gear oil once a year, and check for particals. I flush mine in the shop on stands with car in the air. I use 1 litre of tranny fluid and 1 litre of engine oil.
Shifting is very much like a porsche.

***Lift off gas
***Push in clutch
***Move shift lever
***Release Clutch
***Depress Petrol Pedel

I have seen spider gears come shooting out of case from over spinning, remember when you hold one side of your diff, and the other is free to spin the rpm of that spider gear / axle / wheel is twice of that normally found with both tires sipnning.
I have seen whole gear clusters rounded off, fused togther, main shafts snapped, even a split in the trans case.

That picture does not look like transmission failure to me. That looks like the spider gear in the diff let go. Ask me how I know? :roll:

I can definately relate to you. I just brought my second diff assy in to the house, and put it on the kitchen counter where I'm starting my collection. The first one, the pinion shaft broke, and the piece that broke off wedged itself between the diff and the trans. case. Broke the case, cruising down the main strip in town. The second diff has no teeth on one of the spider gears. I've owned my Swift GT for 5 months and I'm on my 3rd trans 8)

My transmission (the dead one pictured at the top of this thread) according to the last owner, had prior repairs performed to the spider gear. During those repairs it was also fitted with diff blocks and an ACT 4-puck solid hub clutch with an ACT Heavy Duty pressure plate.

All my shift are performed exactly like that, however to be nice to the sychros, all my downshifts are done this way:
* lift off gas
* push in clutch
* shift to neutral
* release clutch
* get back on gas and rev engine
* lift off gas
* push in clutch
* downshift
* release clutch

ive killed quite a few in my day(still killin) the one in my car now is on the way out. i think most of the problem stems from the entire transaxle hoping around under acceleration or breaking. I hap put in an lsd and it makes no differece in the life of the transmission, ive actually broken the secsion of the diff that the bearing is pressed on to(2 times) ive also wrecked the diff housing, 6-8 wrecked 2nd gears , 1 third gear,1crown wheel, 1 5th gear, one intermidiate shaft,,,,,oh the latest ive managed to somehow break out the section of the block that the intermidiate shaft bolts onto so now the engine got screwed from my driveline problems. theses all happened on the road ,not racing

Here's what I found in my transmission. I don't know if the transmission still worked or not, the broken axle kept me from finding out. There was a chunk missing from the pinion gear too. The scrap metal that came out with the oil told me things were not well inside the case.

I can't believe that the gear has eaten through the gearbox housing :shock:

I've got a couple of sets of really good condition gearbox internals that i'm going to put in with the LSD unit I have, as my gearbox has started making a nasty noise.
Seeing the destroyed housing makes me worried because I havent got a spare housing and I'm planning to use the housing for my new parts to go into.
Did you get any noises prior to it dieing?
Phil

In my case it wasn't the gears per se that chewed up the transmission case. I had a partially ejected diff pin. The end of diff pin decided to do a really good impression of a fly cutter with the inside of the gear case. I didn't notice any unusual noises at the time, but I certainly did notice the oil leak. It was burning on the exhaust, and causing clutch slip. At the time I though it was the crankshaft seal, boy was I wrong! :lol: It will make noises once it looses all its gear oil. Expect to hear crunching and banging shortly before terminal failure.

Pictures of my tranny insides should be coming soon.

Been to see my mechanic today, he is surprised that my gearbox oil hasnt gone because of how loose the drive shafts are into the diff.
He told me if I drive it anymore it's eventually gonna go bang. :(

I just bought my swift a couple weeks ago and drove it for less than a week when the diff pin blew right out the bottom of the tranny. What a mess and hassle it is to get replaced. The wrecker that sold me a replacement gave me a tranny of a 1.6l sedan model and told me it was off a GT. The shop that is trying to fix is kept pushing it back because they were too busy and then when they went to start working on it they were thinking the tranny on my car was totally wrong and it was modified to work in there when it was the wrong tranny sold to me! so my car has been sitting for a week now and it hasnt been touched! I am so pissed that this happend in the first place and now it is taking forever to fix.
Rant done, deep breath--------ahhhhhhhh I need a beer!

Even though the 1.6 isn't designed to fit your car, it is a stronger transmission. Quite a few people have gone to a lot of trouble to purposely install that tranny in their GTis.

The weak spot of the suzuki swift would have to be the gearbox....piece of shit it is, my stupid mother got up me for it, but I'd be griding gears trying to change, the gearbox won't change into the next gear and I'd release the clutch, BURRRR, *crap*, clutch in, clutch in. By that time the stupid bitch is already yelling at me (she's buying the car off me)
