With the advent of 6 speed gearboxes the long 5th gear addition to the Std TDI gearbox as some what fallen to the way side
However I had no need to change a perfectly good gearbox as it had no synchro issues and the clutch is fine, but the engine always appeared to be revving too hard at motorway speeds, so I have fitted a longer 5th gear to my existing gearbox.
I went with the 0.659 ratio gear set as this was going to achieve 70mph at 2200 revs (well give or take a few revs, but lets keep the number simple)
At the same time I also changed the gear box oil for Audi G 060 726 A2, the oil which came out of the gearbox was OK, but it was normal old school gearbox oil colour, where as the new oil was clear and it also feels and flows noticeably easer than the oil which came out. This as had a very positive affect on the gear change which is now noticeable smoother and lighter.
The gears are a press fit on the gear box shafts and I have had to grind the legs on a set of gear pullers to be able to remove the gears, they are to say the least 'on tight'
The owl job took me 5 hours, but at least 3 of these was modifying the gear pullers, plus it kept raining and then clearing up so that didn't help either (garage is full of OSS waiting to be fitted and therefore was out of bounds)
The finished result is everything that I had hoped for, quieter motorway cruising, engine now at or around 2200 instead of 2800
yes the A2 will not hold 5th gear at 35mph like it did before on level ground, its now just about 40, ideally changing up to 5th at 45mph if you are not in a rush or 55 if you are chasing it through the gears.
My A2 is a TDI75 AMF running my Depronman remap, which starts to pull strongly from 1800rpm, I wouldn't even thing about the longer 5th gear without the remap as the std map would simply not provide enough flexibility or torque to pull the longer gearing.
I spent some considerable amount of time sourcing the required gear sets, but having found the source that I used I am confident in the gear quality.
If anyone would like to get the longer 5th gear I will be happy to perform the gear box modification and oil change at the same time, for this you get a new set of 5th gear cogs, fitting and gearbox oil change using the above mentions Audi oil for £270, if you need a remap at the same time then I will do this for £20 as you will already be here.
