Transmission issues need help

I have 1999 360 f1 I have been chasing my tell for months, going to a dealer is not an option I'm in small city with no ferrari dealers now the issue is the car drives great in the city for the first 45min then when it gets really hot I will get the f1 error and it wont shift I can hear the pump trying but no go even when i reset with the paddles the option is to let seat for a bit to cool off then I can shift again I bout a tool to check the codes ms908p but was not able to access the tcu module so last time this happened a few days ago I connected the scanner to it since the light was on and sure enough I was able to connect to the tcu I attached some pictures with the errors. The things I have tried already are f1 motor and I'm using a regular 40amp relay also changed the water pump because of bearings noise also wondering if there is readings on the clutch left on the pictures anyway an input is appreciated thanks

Thanks guys for your input so far, when I open the door when cold the pump primes for about 13sec and with the engine off I can select through the gears up down and it I'll top up every 2nd gear up to 6th and down on cold the resovar is about half full i will look for leaks or attempt to bleed through the 2 bleeders, would a tcu from a 2001 part 185301work to program?

 

Meaning? Can it be turned on I can do a re-scan the problem is after I reseted and drove home I can no longer access the tcu the scanner looks for different versions but does not keep any just the other modules or does the car has to be running to be able to detect and read

 

Did a re-scan and I was able to connect to the tcu and the codes that I cleared before are stil there and sure you are correct pis doest record to the module I have the option to write on the scanner and goes through the steps of changing the pis and says complete but when you look at live data still says 5.47

 

Went for a short drive and when I parked the car engine off scanned the modules and no codes are present took pictures of the clutch readings pis is 5.289 mm then turn the engine on and reading is around 11 also the pump reads at 52 and tops up at around 42 bar is it possible that the battery is causing all this issues I have noticed that when I charge it is at almost 13v then drops down to 12.4v and sometimes below all this happens within 30min of running the diagnostiscs

I did a run on a bumpy road well I have no other choice and I will upload a video with the readings but it looks like the reason why it wasn't reading yesterday was because I was moving to slow and not far enough because i did same way today and did not read until i start moving a bit more to start reading the revolutions I drove it for about 10 min and it reads fine looks like its matching close to each other +- 200

After looking at some of the codes I started looking in to the cats upstream and noticed that right is reading and left is at 0 until I start driving then starts reading but very low should both be reading same?

 

Hi tbakowsky based on my last driving after an hour driving in the city it stopped again and i got 2 active errors "0940 gearshift switch lock" and "1708 gearbox output revolutions" f1 pump had pressure and prepping up to 50 bar I noticed that when stopped with the issue the gearbox primary revolutions was still reading in the 200's when should be at 0, do you still think that gear box input shaft speed sensor is the cause or POTENTIOMETER GEAR SELECTION COUPLING SENSOR or something else? thanks

 

After replacing the
Transmission Electronic Sensor P/n 168729
I still have the issue went for a ride after aprox 45 min I was slowing down in to the parking lot and the car wouldn't shift from 3rd I was just rolling then died with the transmission red icon, plugged in the scanner I had p0300 and p0301 but by the time I connected to the transmission module it had reset itself the beeping was gone so no codes but still couldn't shift checked the transmission primary revolutions and even though I was stand still not moving was still reading 143 after trying to chang to reverse a few times the whining stopped the revolutions was at 0 then I could change gears again, what should I be looking in to that might be causing the issue?

 

Ok guys the weather is finally warming up I have taken your advice and bought a used tcu 197533 from an 03 360 spider so I'll be installing it soon and wanted to make sure what's the best pis setting I should set because you have mentioned that my pis was to high, if 5.4 or 5.7 is too high should I set at 4.7 or set same as the old tcu also wondering if there is a way of importing the other driving settings or is the pis & new closed clutch position the only setting that can be set or whatelse can do to take advantage of this newer tcu thanks
