6 Speed Smoother Shifts Advice Needed
Any tips/tricks to getting smoother shifts on a 6 speed '08 STI hatch gearbox?
I've noticed that 2nd to 3rd under full acceleration in 3rd isn't the smoothest and you have to shove it which quite a decisive action! I'm still getting used to the car having only just bought it and notice I sometimes miss third as I move across the gate too far! Car is running 450bhp/450TQ so am just wondering if perhaps I need to look at some gearbox upgrades/supports. eg. STI Group N 6spd Gearbox Mount etc |
You could try a nylon gear linkage bush kit from as performance
, a different gear knob might help, I've got a rallytec one on mine which is longer and heavier and shifting is really nice now. Don't take it the wrong way, but also think about your gear changes, try and smooth it out. |
Thanks, will keep in mind to be smoother with the changes and will have a look at AS Performance.

The bush kit has been one of the best mods on my car, and it's cheap. Makes for a very snicky (made up word I know) gear change.

I'm suffering the same issues on a recently rebuilt WR1 box fitted to a classic. At a recent RWYB meet I kept hitting fifth instead of third. I have the AS bush kit fitted, sure its improved the feel but not solved the third gear issue when changing under load or in race conditions.
Next on my list is a short shift kit but I'm undecided what one to use. |
2nd to 3rd and 4th to 5th have always been the same on all the 6 speeds, the synchros dont like to be rushed :lol1:

All my other gears are fine btw. |
Replacing the rear diff cradle bushes makes a lot of difference to the gear change feel much more solid
|
I've been telling myself its my technique for months, never had issues with any other gearbox.
I'm still using the five speed clutch and fly, would that have any bearing on the poor changes? Heavy duty mounts have just been purchased and a six speed clutch is imminent, we'll see if that improves my technique :) No crunches in the recently rebuilt box. |

Diff brace, box mount, cradle mounts, dog bone etc will keep box stable and aid in easier changes and less rock type motion |
I also struggle with the 2nd -> 3rd technique and been reliably informed that instead of trying to push it up & across into 3rd just go straight up with no force across and itll go straight into 3rd. Still trying to master it but still find myself going up & across

3rd to 4th I some times get problems when booting it
|
After investigating further I've found a split engine mount, purchased uprated engine and gearbox mounts. I'll report back when fitted.

The gearbox naturally returns to centre so you shouldn't need to move the stick across at all. You need literally no pressure on the stick to shift 2-3 it will find its own way home....

I can't believe we're actually discussing how to change gear Loool.

RE Short shifts on a 6 speed, no idea why it wouldnt make life easier, I love the GGR one on mine, just less effort required when changing gear, it did come with both bushes so that will help with precision changes, if it is loose and worn it will make the changes harder. :thumb: |
