Hi. Been searching for a topic regarding my F355 manual suddenly was hard or almost impossible to put in reverse gear. But without luck. I have to use more hand power than one wants. If I turn off the car, I get it in reverse without the extra effort. The feel of clutch travel feels ok, and the car makes no scary noise. Fluid container front (dot4) is almost full. Does this sound like a worn clutch? It doesn’t slip Sent from my iPhone using FerrariChat
It just been slightly nudged out of adjust at the adjustment side of the shift rod. With the car up in the air, put the car in Reverse and undo the lock nut slightly and turn the shaft via a 19mm spanner very very slightly. Then re tighten the lock nut. If it is harder to shift after that, then the adjuster need to be turned the other way... Very slightly as said before. Reverse gear is the best gear to set it into before you adjust because its easy to loose the forward gears when you try and adjust. So reverse is a sure location of were the gears are. Hope this makes sense, and your welcome.
It sounds like your clutch is not releasing all the way and dragging so it's not a worn clutch and it points to something not right in the clutch hydraulics. Once you get it in reverse does the car creep backwards with the clutch pedal pushed to the floor and your foot off the brake pedal? Is the clutch pedal pressure still the same throughout the pedal travel? How are all the forward gears engaging? Are they still normal?
Hi, I’ve just been out testing the things you mentioned. - It does not creep bacwards with clutched pressed in reverse gear. - Clutch pressure feels the same throughout. It grabs about 1/2 way out when taking iff. While driving there is some allowance when I press the clutch before it slips - Forward gears seem ok It seems to be quite ok when car is cold, but when properly warm it seems like the reverse refuses to obey orders. Quite oppisite of what you hear regarding shifting and cold fluids. Switched off the car, and then no problem shifting into reverse Sent from my iPhone using FerrariChat
It could also be a bad pilot bearing in the flywheel. It supports the end of the clutch shaft, the outer of the 2 coaxial shafts. Unlike cars with conventional clutch designs, in a 355 these are very seldom changed because so few understand their purpose. The instructions given for adjusting the shifter were wrong. When the locknuts are loosened there is a centering device on both ends of the shift mechanism. The locknut needs to be retightened without disturbing the spring activated centering of either end. The adjustment is performed with the car in neutral. This is the reason the 355 was the easiest Ferrari ever to adjust linkage centering. Car did it for you.
Your findings above show the clutch hydraulics are just fine and the clutch is working properly. Seeing as reverse is the only gear affected it has to be a tolerance that is off or something has happened only to the reverse gear. I wish I could be of more help.
