Very cool. I can see that there are a lot of specialized tools necessary to teardown and rebuild a tranny. What would a tranny shop typically charge to install a longer 5th gear or final drive ratio?
I just got back from a 1,500 mile road trip with the Jetta. I was pushing it pretty hard, trying to maintain between 75 and 80 mph, and it revs pretty high at that speed. Fuel economy drops way off. When I have the tranny out for the new engine install in a few weeks, I might like to change the gearing too.
first step would be finding out the transmission code so you know what gears you have in the car. if you already have a .75 or .71 and a long final you won't be able to do much better without taller tires. if you have a shorter 5th... start looking for someone selling a .71 for a good price. i don't know of a shop to recommend.

Nice, thanks for the info. Now I need to figure out if a 0.68 fifth out of a fox transmission would slide onto an 020. The junkyards around here are full of old foxes, and no one cares what I take from them (I can rip the engines and transmissions apart and take little bits and pieces,no one at the parts yards give a s*&^ as long as I pay for what I take).
WOW! That first link is fantastic! I wish I'd known about that when I replaced my reverse last year!
I'll post some pics of my homemade "specialized" tools.
5th gear tool: (made from a 12mm socket)
case splitter: (had the guys at crappy tire weld this up for free. Yes, you read that right... for FREE)
FWIW, I've done the 5th gear swap 3 times, and each time I did it with the transmission in the car.
Took me about 4 hrs the first time, can do it in about 2 hrs now. Not a bad job at all, and depending on the ratio change it can make a huge difference.
There's a ratio calculator on those links BlackTieTD posted.
Hi,
I have in my Golf 2 with SB engine gearbox 4T. From what gearbox can I take a 5th gear? My 5th gear is 0,745098. I read here about 0,684, but I don't know in what gearbox is this gear? Can you tell me a code of it? Are in 020 gearboxes better ratios and in which gearboxes, than 0,684?
