i've currently got an ff transmission, which i like, i think it is well geared, so i was thinking of sticking an fn on to my car since it has the same gear but it has a 20% limited slip on it that i could upgrade to a 40% or 80% kit. and i was looking on scirocco gear up to see if there were any other transmissions that might suit, i know i want something nice and fairly tall since our cars can't rev so much (one reason i like the ff) on the gear up site it looked like an acn might be nice because it has a bigger final drive, first gear is about the same but second third and 4th is longer, and then 5th ends up about the same, seems like it might be nice. lemme know all ur findings

My personal favorite and easy to come up with tranny solution is get one of these tranny codes from a mk2 8v gasser: ASF, AON, ACN, ACL, they have a 3.67 final which is real nice, and if you do a lot of highway cruising like me swap out the .75 5th gear in those tranny's for a .71 from a '81 and newer FF, FN, FH, FJ, 7A, or 7D.

So you should pull the 5th out of your current box, grab an ASF and throw the 5th in there and put in one of those peloquin mini slip details like you were talking about. Thats a great budget transmission right there.

i bet that would put my top speed alot higher, currently ive gone to 105, and could have gone to 110 easily. i dunno about the 4th gear, i kinda like whats in it now, but since third is taller as well it's probably all good.

If you've got the gearbox apart, you might want to swap those stupid kamakaze lemming crownwheel rivets for proper high tensile bolts. So says the six BIG holes in my gearbox. :evil: page39 chapter9 Bentley.
On the bright side, it took more than 100 miles of 90mph motorway with nil oil to sieze up outside my house. So I saved on a towtruck

atleast now you have an excuse to upgrade

are any of those trannies going to be any stronger than what's on there now? I've got an '82 with the .75 5th and I'm putting in an AAZ, I was just gonna baby it, but I've been thinking of going with a stronger box.

RabbitJockey · « **Reply #6 on:** November 12, 2006, 02:30:25 pm »

if you want something much much stronger you'll wanna go with an 02a transmission from a tdi or pretty much anything past 1999

I put a cryo'ed 3.67 ring/pinion gear set in my FN transaxle (already has a Quaiffe limited slip). Have'nt had a chance to get it on the road yet, but it should be a nice match with my 1.9D engine.

can the inside gears be swapped around? I bought the 4-puck PD clutch for the o2o already, I'm down with swapping internals around, I could cryo treat them too, that should take everything a VNT-15 could possibly throw at it. only going to be able to throw 16-18psi in it anyway.

AMC, DFQ, CHE, i was looking on gear up, looks like these mk3 transmissions would be rather nice as well, 3.67, 1=3.45, 2= 1.94, 3= 1.29, 4= .97, and 5=.80. i think 5th gear would need some changing on that haha. could be a little tall, but i think the later transmissions could take a little more beating

RabbitJockey · « **Reply #10 on:** November 12, 2006, 05:28:11 pm »

holy moly, these would be even taller, but whos to say taller is always better...

ATH, DFP, CHD

i'm also kinda curious how important the limited slip is, alot of the burn outs i do come in on both wheels, and it's fun because the front end floats around then haha

Well since my commute is all of 2 miles Ive got my stock AGS box. I plan on swapping out the 3rd and 4th for some closer ones. More like an AUG box with the .75 5th and the 3.94 R&p.

Really good site with my Favorite pic ever....

I just drove about 230 km to pick up a CHE tranny with 0.71 upgraded 5th gear, and 80% limited slip for $200 bucks... thanks to burn_your_money for the heads up. Only 289000km on the tranny too... awesome deal!!!!

cant wait!!! its from a mk3

Final 1st 2nd 3rd 4th 5th
3.67 3.45 1.94 1.29 0.97 0.71

about 125 kph @ 3000 rpm... can you dig it? man i think i'm going to just tear my old box apart and learn what i can... its not worth much since the gearing sucks... barely 100 km/h @ 3000 rpm sucks! great for passing on the highway, but not much else.

only regret is that i didnt see it sooner... not that i would have had the $1500 for the tranny + 1.9TD... that had an upgraded turbo from a 1.6... but still... what a deal for a nice big motor.

Cryo'ed? Not familiar with the term.

Just out of curiosity, how well does some of this stuff translate over to the 016 VW transmission and a 2.0L 5-cylinder? Stock gearing in the trans puts me right around 60mph @ just under 3k RPM in fifth gear, which sucks a good deal. 4.11 final drive and a .9x fifth gear are gross.
