Heres Why Paddle Shifters are Stupid Matthew Curran: Not sure how this discussion about paddle shifters could be considered complete without at least mentioning that there are at least two basic variants of automatics with paddle shifters, since which version youre talking about determines if its a gimmick or not. The first version is paddle shifters controlling a standard automatic transmission that uses a torque converter (hydraulic/fluid coupling) to transfer power between the engine and transmission and allow for a speed differential between the two (i. e. so the car doesnt stall when idling in gear. These versions are slow to shift (in stock form, they can be modified, but this usually makes them undesirably rough for daily driving, relative to a good driver with a manual transmission (which also has the benefit of allowing the driver to choose a speed of shifting that suits the current conditions, result in less power reaching the wheels than is the case with a manual transmission (the torque converter, fluid pump to operate all of the internal mechanisms, etc, result in less efficient power transmission to the wheels, and basically are gimmicks. These appear to be the ones that Scotty is referring to. The second version is a manual gearbox that uses a clutch (older supercars, e. g. 1990s Lamborghinis, would use a single-clutch system, sometimes two clutches (DCT or dual clutch transmissions, might be a VW trademark, now used in pretty much all computer-controlled manual transmissions, to transfer power between the engine and transmission. Since these are just a computer-controlled manual (computer pushes the clutch in when the car slows to a stop to prevent the engine from stalling and while shifting gears, so no need for a user-operated clutch, their power-transmission efficiency is the same as that of a manual, all else being equal. These transmissions also shift very quickly, with the dual clutch variants shifting more quickly than would generally be possible with a standard manual transmission (maybe not a racing transmission, like a dogbox, but were not talking about 5k-10k aftermarket racing transmissions here that would be impractical for road use due to their rough engagement, among other issues that are not concerns on a race track. The DCT variety shift so quickly because they preselect the next gear using the clutch not currently in use, allowing a shift to be completed by the computer disengaging one clutch while simultaneously engaging the other, allowing for full-throttle shifting without strain gauges or other fancy power-cutting devices used to enable this on standard manual transmissions. In my opinion, the only trouble with these transmissions is their complexity (cost/difficulty of repair) and lack of headroom for modifying (stock, the VW types can only handle 300 ft-lbs. of torque, I believe due to the need for two smaller clutches, relative to a standard manual transmission, needed to fit inside of the bellhousing. While I would forgive Scotty for failing to mention the latter type of transmission if they were only sold on supercars, theyre not. These transmissions have been available at least on VWs, even Jettas, for years.

When bleeding brakes, the two-man system, put a small clear hose on the bleed nut. Put the hose into a container with a little bit of brake fluid in the bottom. You want the end of the hose in the fluid. Is you bleed the brakes the air comes out but so does some of the fluid. You dont end up with fluid all over the ground. The other thing is if someone lifts the pedal too soon if its such anything in itll be brake fluid not air. This is a trick I stumbled upon about 20 years ago doing backyard mechanics. Or if you prefer shade tree mechanic. It works. The plastic tubing normally associated with patients receiving oxygen happens to be about the right size. You put the big and on the brake bleed and you cut the tube about 18 inches long depending on your wheel diameter. And youre good to go. Another advantage to this system as you can look at the brake fluid thats coming out. If its really dark thats a problem. If its really dark it could mean that your master cylinder is going bad or you have a bad wheel cylinder possibly. Essentially if its really dark it has little bits of rubber in it. Never a good thing.

I recently test drove a Citroen C4 Grand Picasso, paddle gears and didnt ike them as they were very laggy, I double clicked thinking it hadnt worked and it dropped 2 bloody gears. Left it in auto for most of the test drive. As I pulled up looking at the steering wheel it had at least 16 buttons and 4 dials Thats just on the steering wheel. Havent got the money to keep electrics going, recently laid off with a factory closure so no way was I going to buy these luxuries, French electrics are crap. I need reliability for my family so I left it and bought a Mazda 5 insteadand its great. Replacing the back discs and pads at weekend as theyre shot. PS A car accelerating on its own can be a vacuum fault/leak, had it on 2 different cars. 1. 2L Subaru Sumo with a carb and a 1. 3L Austin Maestro (my first fuel injected car) from years back. Both had lots of vacuum pipes and apparently it was to help get them through the new EU emissions regulations back then. Keep it up Scotty. Cheers man.

scotty is so full of shite he squeaks when he walks. He wastes a huge amount of time and not only never gets to the point, he ends up convincing me he dont know jack shite about anything technical on cars. For example, Fords Edsel had a pushbutton shifter sitting on top of the steering wheel. Chrysler copied the idea and this is in the mid 1950s. It was actually an expensive setup, so the shifter was moved down to the floor to save money on the linkage. The shift paddles on the steering wheel was for rally racers who were concentrating on keeping the car on track on all sorts of terrain. To save space in the Formula 1 cars paddle shifters became a necessity. Previously, race drivers had to manually shift and drive with 1 hand with cars going over 200 mph. Accidents at those speeds were always fatal. The paddle shifters have saved lives, cuz the driver had both hands on the wheel.

Dual clutch with Paddle shifters will destroy a manual all day. This is coming from a person who use to be a die hard when it came to cars with manuals. I use to have a 1995 M3 as a track car. It was set up very nicely, one day I totaled it at Road America on a track weekend. My next track car was a 2011 BMW 135i with a DCT. Ill never go back to manual on the track. Its better in every way. You just can match the speed and precison of a DCT with paddle shifters. On the street its just as good as on the track, plus if you get in those bumper to bumper city conditions you just switch it over to automatic mode. I liked DCT so much when it came to a new daily driver I had the choice between manual and DCT on my 2016 VW GTI, I chose the DCT. Sure Paddles on your run of the mill automatics might be useless, but on a DCT they are outstanding.

Best: proper stick shift, because they feel better, will always hold the gear, require driver involvement and are fast becoming a theft deterrent. Good( for people without a left foot ): a manumatic on the floor console shifter ( natural positioning) with forward for downshift and back for upshift, if its quick enough shifting. Ok: a manumatic like above with + and - reversed. Crappy: paddle shifters in most cars, because theyre in the way, unsightly, usually laggy as hell and with all the other umpteen functions on the steering wheel already, do we really need more clutter. Sucks beyond belief: paddle shifters on an SUV because theyre pointless. Pet peeve: manumatic of any sort that wont hold the gear until the redline without safety shifting for you. Caveat: super cars costing 150, 000 or more are excluded from this list by default.

Scotty you made my dayIm not a mechanic but, the 3. 5L EcoBoost V6 used in extra stress applications like big-SUVS and pickups just kind of never made sense to me. The 5. 0L V8 in the F-150 is the better engine choice. I tell all my friends to be wary of todays small-displacement turbo-charged engines that are applied in big vehicles. To me it just sounds too good to be true and auto manufacturers are definitely not looking on the engine longevity perspective. I own a 2016 Ford Transit that uses the 3. 5L EcoBoost V6(300HP) and its the least powerful 3. 5L variant. I must say, the engine feels great and never feels under powered. I also believe that the engine is not under much stress due to lower output compared to other higher output variants of the 3. 5L. What do you say Scotty about my Transit? Will it last?

The perfect response to the consumer paddle shifter question. A fun gimmick - hey, they want to sell cars. Story: There was this guy around town that mustve liked NASCAR. I saw his car several times. It had some checkered flag decals and such. It was a common NASCAR body style but didnt appear to be too hopped up. It did have the NASCAR tires they used to sell, although. So, one weekend I see the car pretty close to the car in front of him - probably some risky but attentive driving (while envisioning drafting or even that bumper camera close action. The next time I saw the car the front end was wrecked One of those LMFAO times (assuming the story was he was burning down the Talledega track and got into him. OMG, it was so funny seeing this play out. - I hope it was, in the big picture, a minor incident.

Its kind of sad seeing all the hate towards paddle shift semi automatic gearboxes. The ones designed for formula 1 racers are very complex, and perfectly engineered, true. And the ones you find in road cars are of a sub par quality, also true. But nowadays, especially in higher end vehicles paddle shift gearboxes are second to none in terms of driving potential. There is no way in hell a manual 6 speed gearbox will be quicker than the automatic alternative. In modern times the only pros for manual transmissions over automatics are the feel transferred to the driver and possibly longevity. STOP CRYING EVERYONE, nobodys going to be taking away your toys but the world must advance. The future is now old man.

What are you talkin about paddle shifters are no good every car that Ive driven with a paddle shifter I have enjoyed it theyre not meant to be used as youre showing in an F1 car theyre meant to make a corner on a highway or an offering more fun or a few times they want to downshift as a way of an engine break along with their brakes heck you put in Elantra 2. 0 in sport mode and use the gear shift electronic in Colorado is it in engine brake going down a mountain 3rd to 4th gear little bit of the break fun ride paddle shifters allow you to keep your hands on the wheel during those switchbacks as well as it is pretty fast faster than what most people can shift a manual transmission
