Evening everyone
In the last month I've done plenty of work to improve the gearshift on my 997.1 and just wanted to pass on my experience. I did each stage seperately and test drove the car inbetween so I could gauge the difference each step made.
To give context, my car has done 26,800 miles, at around 26,000 mile I changed the gearbox fluid to Motul gear 300 (simply as it was available in 1 litre bottles and met the required spec) and the change went from average to dreadful. Think hard to engage 1st when stationary, having to double declutch 1st to 2nd etc. When warm it was better but remained a little spongy.
So here was the sequence I did things in and the percentage relative difference in brackets.
1. Engine mounts. I went for the OEM engine mounts (about £250) and the difference was amazing (50 percent). 1st engaged properly, no double declutching and the change was perfectly acceptable with just this change. 50 minutes to fit. The engine mounts sold by D911 as OE match are literally that- clearly the same item as Porsche genuine.
2. Gearbox mount insert (20 percent). I went for the yellow road powerflex insert and any NVH increase was gone within 10 miles. The shift felt more accurate. An hour to fit but I have a 2 post ramp to help, which saved time. Cost about £40 from memory. The play in even what was an excellent condition gearbox mount was quite telling.
3. Gearbox fluid back to Mobilube PTX. (20 percent). Less than an hour of true work, I drained overnight though. £11 a litre of fluid bought in bulk- the I have 2x 4 litre batches left for sale at cost if anyone needs any- the spongy feeling went and at this stage, with the low mileage of my standard carrera shifter, the shift was good with minimal play. At this stage I was more than happy
4. The Alex Yates SSK (10 percent). £170, about 2 hours to fit, adjust cables and reassemble the dash. The icing on the cake. Insanely good tolerances, the silver axle ends as I call them had to be gently pressed into the plastic housing. Bushes perfect fit, No play in the the shifter mechanism at all.
Total expenditure was about £500 but all should be good for years- in the case of the ssk indefinitely.
Hope this helps to anyone with similar issues.
