430 F1 Shifting Issue

There are numerous threads on this topic, unfortunately, most often without a clear solution path. I'm still struggling with my '06 F430, after thinking we finally had it sorted (documented on this thread > https://www.ferrarichat.com/forum/threads/f430-f1-shifting-woes.608033/ ). Quite a few F430 owners wind up throwing expensive parts at the problem (usually a new hydraulic pump or maybe just the pump motor) without actually getting at the root cause of the problem. Dealer service experiences frequently appear to be just as frustrating (and even more costly).

There appear to be a very few F1 savvy folks that seem to be well acquainted with this issue and knowledgeable enough to methodically diagnose what aspect of the F1 transmission is causing the issue. I did pay for a consult with http://craig-waterman.com/?p=584 and felt he gave me some good suggestions for trying to narrow down the problem. We did discover the leak rate for the ediff valve was above the recommended threshold, but I'm still having the shifting issue after replacing the valve (plus the accumulator more as a matter of good preventative maintenance).

After discussing this with our indie mechanic, we're going to re-examine the ediff valve leak rate again to make sure it didn't degrade and probably check the infamous bleed screws that appear to be loose on so many F1 transmissions and then bleed the system again. There is another FC member, that services these transmissions and appears to be very knowledgeable (https://www.ferrarichat.com/forum/members/windsock.42675/ ) that will give some friendly advice and also does pay consulting. We'll probably tap into his knowledge if our next steps aren't successful.

 

Many of the F1 problems are caused by not servicing the F1 system every three years, which Ferrari finally figured out was necessary.

Before anything .I would pull codes and check fluid level.. the next would be to pull all stats/live data using a SD computer or equivalent equipment.

Once you have this .. things will begin to pop

Hello Linsey,
I had the same symptoms....I added a little F1 oil to the reservoir that is located behind the right rear panel. Search FCHAT for checking level as you do not want or need to add very much fluid. If you fill too full, I hear it will run out the overflow and onto your garage floor....after you add the fluid, crank car, let Idle for a few minutes then take the car for a ride and all should be good again.
This worked for me a few months ago and no issues since. Hope this helps! Enjoy the ride!

Sounds like the shift linkage potentiometers to me. They come as a pair wired together and cost about $500 from Scuderia Auto. I had to replace 5hem on mine after error codes pointed towards them (no SD3 was necessary).

 

Bought a 2005 F430 with 25k (km) on it and had sportatic F1 issues within 30 days after purchase. What happened was after driving for 30 or so mins on highway would go on exit ramp and downshift 6th to 1st. And sit at light. When light turned green it would "clunk" and have trouble shifting, skip to 2nd, the 4th, shift warnings etc. Turn car off in intersection, wait 5 mins and was able to get out of road. I reported to dealer, they had a look but they couldn't replicate, brought it home and happened a couple more times. Dealer ran tests, replaced accumalator but same issues. They ended up replacing complete F1 hydraulic kit which fixed the problem. Shout out to Ferrari of Ontario for covering repairs

Going through the process right after purchase had me doubting the idea of an F430 and considering even a California instead, but so glad I stuck with it, absolutely love this car

 

Not to side track thread but I have heard about this f1 kit ..does anyone know what this kit contains ?

TIA

Has the trans been serviced at all recently?

sounds like there is air in the lines.
