Roll Stop Newbi Question

Maybe someone can tell me what happen or possibly damaged.

I was loading my 2003 Modena F1 up on to a car trailer. I had it in first gear and gave it a little gas to hold it in place on the ramp. It started rolled back a little as I let off the gas and so I put on the brake which caused the car to stall.

My clutch was just checked and it has about 70% wear left in it.

Is this normal? I could see this happening with a manual trans but this is both my first Ferrari and F1 paddles so I am not sure.

 

The scenario you describe could be normal. It is not advised to hold the car in place using just a little gas as this causes a fair amount of clutch slip. The clutch was probably partially engaged and when you hit the brake, it stalled at that low RPM.

Best advice when loading a car onto a trailer is to use a winch and pull it on. Much easier on the clutch.

Second best advice is to "bump forward" as opposed to "slip forward". The idea is to have the clutch fully engaged or fully released but not slipping. Bumping forward involves a little tap of the gas to engage the clutch and then the car bumps forward a foot or so. You have to be lined up well so you don't hit anything in the trailer. The fewer of these bump forwards the better. Get yourself lined up and have a friend watch, then bump forward 2-3 feet, brake, reassess position, bump forward again, repeat.

Slipping the clutch in reverse gear is even worse according to many FChatters. Several have reported clutch damage from repeated backing out a sloped driveway or repeated backing onto a trailer.

 

As I understand it, slipping the clutch in first gear, like in heavy traffic or a trailer loading, will cause the disk to expand. If the clutch PIS setting is too close this will cause the engine RPM to be pulled down due to the clutch friction and the TCU will interpret this as a problem causing an engine shutdown. Once the disc cools down and contracts, it works fine again.

I read that somewhere....

 

This happens to me in my 2003 F1 Modena. I have a steep driveway that turns just as it meets my garage and to make matters worse I park on a 4 post lift so I have to be very careful how I pull in. This having to go slow up the hill has caused me stall a few times though I am getting better at it and have been using a techniques as Teachdocs has described. The car always starts right up and goes without any issues and the dealer did not find any permanent issues upon inspection. The fact that you can smell clutch afterwards is pretty disheartening though and I can see the dollars flowing out of my bank account.

 

The reason the clutch slips more in reverse than 1st is that reverse is almost as high as 2nd gear. Intentionally slipping the clutch in 1st or reverse will really shorten clutch life.

 

The clutch never fully engages in reverse. It's always slipping. A lot of reverse will definitely shorten clutch life.

 

Taz is right, again. It will fully engage in R but you have to be going pretty fast because the gear is tall.

 

I guess I've never gotten it up to speed in reverse. LOL

I was under the impression that it was not a speed issue with reverse. It just will not lock up. But I don't think I'm going to be trying it anytime soon.
