2002 Audi A4 Fwd. Will A Quattro Transmission Work

How much would an automatic to manual transmission swap cost?

It depends on what vehicle and what manual transmission. In general, on a rear wheel drive vehicle, swapping out the auto for a stock style manual isn’t terrible. Stock manual transmission assemblies can run anywhere from $1000 to $2000 on common vehicles. Removal and replace usually takes between 5 and 8 hours. Adding a clutch pedal and mounting a cylinder depends on the vehicle and again, whether it is aftermarket or stock bolt in. The problem is, you can’t always just bolt stock replacements back in. If the parts aren’t modular, then adding a pedal can take some time.Swapping out the flex plate for a flywheel and installing a clutch only adds about 15 minutes to the overall labor time.I doubt that manual and auto trans on any vehicle are exactly the same length, so the driveline probably needs to be cut and re-welded. This part of the job would be outsourced by most shops and may run 100–300 bucks. Measuring everything properly so accurate info can be given to the driveline shop takes time. Pinion angles must be checked with the new driveline and in some cases must be adjusted which sometimes requires different spacers being installed under the rear axle.Measuring and cutting a hole for the shifter and boot takes time. Re-wiring the neutral safety switch takes time as well.So, you have the parts cost of transmission, pedal assembly, reservoir, clutch fluid hose or cable, clutch kit, flywheel, driveline modification, any additional brackets that must be bought or made, shifter boot and neutral safety switch swap.Then you have the standard labor of removing and installing the trans, plus the extra labor of making everything work. The extra labor cost is very hard to pin down without knowing what vehicle and if you are going with nice, aftermarket parts or trying to stick with stock parts.Trying to covert a front wheel drive vehicle to manual has potential to be easier. It would be (possibly) easier and cheaper to just buy a complete motor/trans assembly and swap out the whole thing. Sensors might need to be modified and some holes cut in the firewall, but anything can be done.So, I dont know. On old trucks you might be able to do it for 2500 if you buy all new components. On newer vehicles it gets more and more expensive the newer you get as more and more components must be modified or swapped.

What's the difference between Tiptronic and automatic transmissions?

A Tiptronic transmission is an automatic transmission that includes an option to switch out of automatic mode and upshift or downshift by using paddles behind the steering wheel or by using the gear lever itself. The name Tiptronic is a registered trademark that is owned by car manufacturer Porsche. In Tiptronic, manual shifting is controlled through buttons with a plus sign for up-shifting and a minus sign for down-shifting. This is similar to what many sports cars use in order to give an authentic feel. While the first system was originally produced by Porsche, later systems have adopted similar technology, with the same name.Tiptronic systems allow drivers to choose whether they want to drive automatic, where the computer does gear shifting or manual mode where the driver has the opportunity to change the gear. Other systems have tried to emulate the feel of manual without giving you full control, but the Tiptronic transmission is the first device that offers a choice. The system has safeguards in place that keep drivers from going past the RPM red line when operating under manual control. If drivers fail to use manual shifting for a certain amount of time with Tiptronic, the software on the transmission automatically switches back to automatic and controls all shifts through the computer once again. It is then necessary to turn it on again to go back to manual.The Tiptronic, is also known as manumatic transmission, so allows the user to shift gears without having to operate a clutch. The system has built-in safety features so that the transmission cannot be damaged in the event of driver error. The technology is licensed for use by other manufacturers such as Volkswagen, Bugatti, Lamborghini, Audi, Seat, Skoda and Land Rover.

What happens if I use the wrong transmission fluid?

For an automatic transmission car a lot of things can happen.The transmission might start slipping, not engaging into gear properly, shifting rough or literally not work at all.You might see progressive damage to the tranny. At first it seems fine, but then it starts slipping or shifting poorly. The transmission might fail altogether.Sometimes you’re lucky and putting the right fluid in makes it work normally again, sometimes you’re not so lucky and the damage has been done, requiring a complete rebuild or replacement of the transmission.It can also get quite interesting for manual transmissions. You see, manual trannies use synchronizer rings to match internal gear speeds. The synchro rings do their work while you’re moving the stick into gear. It very rapidly synchronizes the speed between the input shaft and the gear you are selecting.If you use the wrong fluid, these rings might work less effective. This can cause the shifter to feel stiff, or you cannot get the shifter into gear. It might even grind as you try to put it in.Using the wrong fluid can over time wear up your synchronizer rings to premature failure, requiring an expensive transmission rebuild.Without the synchronizer rings the transmission cannot shift normally. You will grind the gears or not shift at all. You will need to double-clutch and rev-match, like the big rigs that don’t have synchromesh units at all.Using the wrong fluid, can in BOTH types of transmissions wear out bearings and gears faster than usual, making for strange noises or catastrophic failure.I have no experience with CVT transmissions, but from what I have found is that putting the wrong fluid in a CVT transmission will most likely royally mess it up. It might work for a little while due to the little bit of CVT fluid that is still in it, only to very suddenly stop working and never work again.Use the right fluid for your tranny. Fluid isn’t expensive. A new tranny is.
