I have a new to me 02' 360 Modena Spider with a manual six speed and 17k miles. It shifts very hard into second gear unless I blip the throttle. I had the car in the shop and was told it needed new shifter bushings so I had them replaced, but it hasn't imporved the shifting. I just saw a video online regarding driving a 99' 360 Modena six speed manual and it showed how the proper way to drive the car was to blip the throttle when shifting into second as the flywheel is undersized. Does anyone know if this is true, should the car shift smoothly without blipping the throttle or is this a worn synchro issue?

First of all, it's very important to make a distinction between upshifitng to 2nd and from 1st and downshifting to 2nd from 3rd. Blipping the throttle should help on a downshift, but it's exactly the wrong thing to do on an upshift. To match gear speeds, the engine RPM must drop for an upshift.

That said, the 1st to 2nd upshift is always the hardest on the transmission because it involves the greates amount of torque multiplication applied to the driveline. So anything wrong with the shifting will show up first on that shift. My 328 doesn't like to do a 1-2 shift until it has warmed up considerably, so I shift from 1st to 3rd until I see some water temperature on the gauge.

A 360 has a much newer design, and it should be OK immediately, so it suggests that something is wrong. The most likely cause is that the clutch isn't disengaging completely. Any clutch drag will make shifting more difficult, and, like I said, the 1-2 shift is where it will be most evident. A simple clutch adjustment could take care of it, but there are other reasons why the clutch might be dragging. Confoundingly, a leaking crankshaft oil seal can sometimes result in a dragging clutch.

But anything that puts drag into the shift linkage will give a similar symptom. Your mechanic may have had the right idea, but not solved the whole problem.

A worn synchro is another possible problem, and if it has been hard shifting for a long time, the synchro could be worn as a result. Bear in mind that it may be a symptom and not the root cause.

Anyway, try the easiest possibility, the clutch, first. If that doesn't do it, then look at the linkage, and then inside the transmission.

Thank you for your input. I was talking about upshifting, it is next to impossible when cold. Shifting from First to Third is no problem and is what I usually end up doing. When the car has warmed up there is still a first to second upshift issue especially under hard acceleration. I'll have the Clutch checked out and see if that fixes the problem. The Car has just had all it's Major Services at one Ferrari Dealer and was Inspected at another, so I doubt, or should I say hope there are no Seal issues.

Thank you again for your input!!!!
