360 F1. Reverse acting strange. Help.

You say the car is an early F1 model, but which transmission control unit do you have?
Ferrari has changed part numbers (along with the software) SEVERAL times. If a customer complained about shifting issues while the car was under warranty, sometimes Ferrari would install a new TCU under warranty.
You may need or look at the TCU itself or if you have the dealer or your mechanic run SD2 diagnostics, that data will be on the printout.

 

Try an ECU reset. Disconnect the battery using the disconnect switch, leave it overnight. Reconnect the next morning and then follow the run cycle prodedures here. Read the explanation, too, so you know what the stilted translation means.

If you read page 108 of this document (page 110 of 764 of the pdf):

Under the heading 6 IO settings, a procedure is described using an SD-2 tester. I have had good luck doing this procedure WITHOUT the SD-2 tester. When you read the description of what the SD-2 tester is doing and then do it yourself (instead of the SD-2 tester doing it for you). I have used this procedure on cars that I have had to change hydraulic lines on. It works, but you must follow the procedure exactly as stated.

I use a kitchen timer for the first steps. Neutral for 5 minutes, 1st gear for 5 minutes with foot on brake and parking brake engaged. Then turn the car off and allow all lights to go out. Turn the key back on wait for the Check OK and shift to neutral.

Next instead of the SD-2 running the gearbox from Reverse through 6th sequentially, you do it yourself. You will get the beep if it works or 4 beeps if it doesn't. If that happens start over and do it again.

Hope this helps. Let us know if you have success.

 

Since the link won't work, or I don't know how to properly embed the link in my post, I can describe it. The link is to ferraridatabase.com. When you get there go to Downloads. From downloads go to Workshop manuals. From there, go to Volume 2 of the 360 WSM.

 

I'd get the p.i.s checked. If it's fine when it's cold but plays up when it's hot the p.i.s could be set to low. Anything less than 4.7 can cause it. Also sticking clutch release bearing seals can do this, traceable by watching for a varying p.i.s figure when the car is hot.

 

Sounds like a small fluid leak which only becomes an issues when the fluid heats up. Mine did the same thing when driving in slow moving traffic. The guys discovered a leak near the actuator i think.

Also, if you are having an issue going into reverse put it into first and then straight into reverse it worked for me !

 

I have a 2000 360 F1 that would not shift from N to R when the engine was warm. It would shift from N to R just fine when the engine was cold. When the engine was warm, though, it would shift from 1 to R. The dealer (Ferrari of Houston) did not know what to make of the issue, so their service department said they would do some research. During the week that they did research, I began to take notice that the shift form 1 to 2 was very jerky when the engine was warm. Also, I began getting an audible alarm (beeping similar to the beeping you would normally hear in reverse) when starting off gently from a standing start in 1 or when backing out of the driveway (in R), but again only when the engine was warm. When I provided this additional information, the dealer recommended replacing the clutch. It is now very smooth and reliable. So, you may be seeing the early signs of a spent clutch.
