Purpose The Fox’s stock are pretty good. I personally had 2 Foxes, both with the 4-speed transmissions. Contrary to you might think, the 4-speed is not all Acceleration is pretty good, you shift as often (so that when, uhh, driving with 5-speed cars), the 4th is nice on the highway (

2600 RPM @ 100 and they’re virtually bulletproof!

when I finally came a 9Q (the code for the 5-speed transmission found in VW Quantum diesels), I decided to go for it. I knew the car drive differently with a but I wasn’t aware of how much a it would make. I will to say that this should be the first modifications one should do, if for improving acceleration (the being removing the exhaust and preferably upgrading the entire — exhaust manifold, catalytic converter and cat-back pipes).

The 9Q’s gearing like it has the best possible of gears to yield amazing as well as good highway RPMs. The Audi 2P transmission is the same through gears but it’s 4th and 5th are closer together; will result in slightly acceleration, but will also higher cruising RPMs.

The is fairly straightforward, as long as you all the parts needed. It can be performed the course of a day, providing you the skills, parts and access to that might be worn etc.).

Where to find the 9Q? Junk VW Quantum turbo diesels are rare these days, so this transmission will be tough.

What to get?

the transmission and acquire it.

Grab the shifter linkage — you everything from the transmission to the shift lever (even the box at the bottom of the rod that has the knob on If the donor car is missing the linkage, rod, or any other parts, I am certain that the following have identical shifter components (all with engines and 5-speed manual VW Quantum, Audi 4000, VW

Depending on the mileage of your and the state of these parts, it be a good idea to buy: new disc, pressure plate and bearing, as well as a new rear seal, and transmission seals (if appear to be leaking). My 9Q didn’t any signs of leaks and doesn’t so I didn’t change any seals. The main seal on the engine one around the crankshaft) was moist, so I it. I also left my stock Fox and all other components.

If you have the getting a lightened flywheel help with acceleration more. Be aware that no what any web site advertises, do NOT have the same flywheel as Volkswagens!

VW and Audi do not recommend to the transmission fluid, ever. was a little bit low, so I added a additive, and left the fluid was in there. Redline Manual Fluid is apparently very but costing $8.50 USD per quart, it is not A friend of mine (whose car transverse transmissions several per year) uses engine oil in his due to the low cost of engine oil.

The drive flanges, transmission flywheel, clutch, and everything are identical to the Fox transmission, so there’s no work involved. The switch for the lights is in a different location, but the Fox reach without any problems.

If any undercoating is missing, get rid of any rust, it with rust-paint, and then with undercoating. Some undercoating is bound to get scraped off the install, so fix that too.

Inspect the bearing on the 5-speed. Also sure each gear properly.

One way to this might have to replace the switches and bolt something less extrusive; but the didn’t do anything bad, so we did it way.

Thoughts I got accustomed to the 4-speed’s through driving 4-speed for about 7 years. So while I that the better final and tighter gearing would better acceleration, I did not realize how a difference this would With the 4-speed, even if I at redline (fuel gets cut at RPM on my Fox), I’d drop the powerband in the next gear. this 5-speed even at about 5000 RPM, I have good power in the gear. I’m writing with only about 2 of driving with the 5-speed, so I add more thoughts later, as I the transmission, as I test it out, and

In summary: if you have a 4-speed, and can get a get it now! I presume that with everything else stock, the 5-speed will out in the acceleration department.

Isn’t it that Volkswagen’s engineers use heads? In what other of car will a transmission from a model fit without any problems a 1992?

And in case anyone’s the 4-speed will go in my Dasher, so not for sale.
