i've always wondered this
so many of us would agree that some of the best shifting manual transmissions are the older Honda trans found in Integras and Civic Si's. But regardless of what you actually prefer, we can all agree that the older manual transmissions from Honda just felt so much better to shift than just about anything on the market today. (if I'm wrong, correct me since I haven't driven every manual car available to man).
I understand engines needing serious change to cope with emissions regulations (thus losing character) but manual transmissions and clutch interaction should be pretty much completely unchanged, unless you're perfecting it. Having driven quite a few recent manual cars (including my Mazda3) it gets me wondering why every manual transmission ever produced today doesn't drive and feel as good as the best manual ever built.
Why is that? Why do some manuals (engineered today) feel spongy, vague, lock you out of a gear on occasion, have "lazy" synchros, have long spongy clutch engagement, notchy crunchy shift feel...etc. Would manufacturers not have weeded out all of the things that didn't work well with their old manuals 20 years ago? Did they not drive a competitor's car at some point and say "oh sh!t, yeah that's nice lets do that". How come a brand new Corolla shifts like your cutting cheese cake with a wooden spoon, or a 2017 Subaru Impreza STILL shift like moving a spatula in a tuna can full of coins?
and question 2; what hardware differences have the better transmissions had that made them so much better than the others?

nothing yet, eh? no trans experts out there?
As far as what's different? A few things; if less money is spent, then less time is spent on getting the dimensions and materials just right, the parts aren't going to be built with the same precision, etc. Think about a rifle action; companies like Remington spend a lot of time and money getting those parts very precise and well engineered. Meanwhile, I could produce a similar motion with a dowel and a PVC pipe, but it wouldn't be nearly as well functioning.
And FWIW the 6MTs in late-model Porsches and M-cars are still pretty good. Short throws, stiff clutches, and notchy in the right ways. Miata's probably isn't the best but it's not bad either.
Also a secondary theory for the crappier feeling shifters. Torque numbers are much higher than golden era Honda’s. For higher rated trans, all the moving parts have to be beefier.
And for FWD applications, I believe most modern cars are cable shifters, instead of a linkage. I know with VWs, the shifter feel went downhill when they switched to cable. At least in my opinion. I am currently in the process of switching a later cable trans to rod linkage in my rabbit, and I am really curious how it’s gonna feel.

I've had 17 cars. Sixteen of them had clutch pedals -- the outlier was a 2014 BMW M5 with the dual-clutch transmission. The first was a 1975 Oldsmobile Starfire (old dude here!). The 16 included one Toyota (1982 Supra), one Mercedes (1988 190e 2.3), eight BMWs (three of which were proper M cars [2002 e39 M5, 2008 e90 M3, 2014 f10 M5]), four VWs, and a Mazda. In general, the RWD cars have had the better shifters. I think they've been a mix of ZF and Getrag, although I think Mercedes actually built their own.
The BMWs all had pretty good shifting action, though it got harder and harder to drive smoothly as HP ratings went up. The last manual BMW I had was a 2011 550i M Sport -- 400 HP, 400 lb-ft. My current Miata has a pretty nice, smooth gearbox, too, and all of 155 HP.
But the car that still sticks out in my mind as having an amazingly sweet shift was -- of all things -- a 1985 Peugeot 505 Turbo.
My BMWs had very nice shift knobs -- either leather or walnut or both. Relatively short throws, nicely weighted and sprung well for accurate shifting. The Peugeot had a long lever, and the knob was hard plastic. But the action was so perfectly weighted and sprung, and the knob so perfectly placed that the car could have been designed just for me. Start out in first; hands on the wheel at 9 and 3. Run up through first (waiting for the damn turbo to FINALLY spin up), let go of the wheel with my right hand and drop my arm, palm down. Open palm lands on the lever, shifting from first to second perfectly. Two to three was a light shove with the palm. Three to four, as easy and accurate as 1 - 2, four to five took a little more intent, but was still amazingly accurate.
All these years later, I still remember how satisfying it was to shift that transmission.
Current 1: 2018 Golf R, 6MT
Current 2: 2017 Mazda Miata RF, Grand Touring, 6MT
Previous: MkVII GTI, eight BMWs, two MkIV GTIs (both with VR6), a Mercedes, a Peugeot, a Toyota, and an Oldsmobile, all but one with manual transmissions
anyway, thanks a lot guys for pitching in.

This is a purely hypothetical example that I'm making up to illustrate the idea, but let's say there's some expensive brass alloy that has just the right amount of zinc and the perfect grain structure for a great feeling shift. 20 years ago, a gearbox company could spend time and money chasing down suppliers of that alloy and negotiating a good volume discount. Today, they don't make enough MT's to qualify for the discount nor have enough time to negotiate it properly--and without discount the alloy is too expensive--so instead of raising prices on a unit with dwindling sales, they switch to a cheaper but inferior alloy.
I have the transmission out of a 1990 corrado in my rabbit pickup.
I believe its never been apart. and it still shifts amazingly.
and it explains why honda made such amazing manual transmissions, because they bought huge bulk of manuals.
It sucks cars are designed by "bean counters"
smiles per gallon in a tdi rabbit are unreal
FWIW, I didn't mean it was materials necessarily, but the idea of volume paying dividends. And yeah, penny pinching can be a pain and I hate when it becomes obvious in the product, but at least cars are still somewhat affordable.Originally Posted by fastinradford
How long can I drive on this without it being dangerous. Car has 8500km, didn't even buy my damn winter tires yet and I need to replace my summer.
I'm planning on installing my winter's in about a month and a half. I do about 500km per week so another 3000km until the summer's are off the car.

youll feel it bump around like a badly out of balance wheel, more and more, as you get closer to failure.
i had one of those on a nearly new tire when we had our cla. it got worse and worse until i couldnt really stand it anymore and had to have it replaced.
I've driven a couple hundred miles on a tire that had a bulge on the inside (towards inside the car, not inside the tire). I couldn't see it because my S-10 had a whopping 3" ground clearance up front. First day I had it I couldn't tell because we had a snowmageddon (3 hours to work, normally 45mins). Second day there was a slight vibration that I thought was compact snow and ice. I told my dad when I got home and he looked at it and found the bulge. My mom got angry with me, like a tire manufacturing defect was somehow my fault.
Thanks guys for your help!

I'll give my dealership a try and see how it works.
Damage to a vehicle - Holes in the roadway
Q. My vehicle was damaged because of a hole in the roadway. What recourse do I have?
The complaint must be submitted to the ministère des Transports, de la Mobilité durable et de l'Électrification des transports who will investigate. It must be demonstrated that the Ministère is at fault or was negligent.
However, under section 30 of the Act respecting roads: “The Minister is not liable for damage caused by the state of the roadway to the tires or suspension system of a motor vehicle.”
If they compensate you, it will be on a good will basis if it can be established on the balance of probabilities that the pothole was unavoidable. Also, you would be claiming to the VdeM, not the province (unless it was on a provincial highway).
