"Should it be shuddering????"

Hello all...

My hunt continues for the right 4200 CC.
I've just seen a really well presented facelift model that could fit with my budget. Test drove it today and was a little concerned when moving off. With the engine/gearbox a little cold, the car had a tendency to shudder in 1st gear. Is this normal? Something to be wary of? Or just how these cars are?

As the car warmed up, the shudder (only in 1st gear) lessened and eventually disappeared.

On a previous test drive, the vendor advised me to move off from cold with the car in AUTO. He didn't explain why, I just went with it and I'm wondering if this is the standard work around to avoid 1st gear shudder when the box is cold...

Any input welcome.

Best

Never ever used mine in Auto. I don't recall any shuddering but I do recall it being a bit 'prompt' when cold

They are certainly more ‘jerky’ when cold. Just make sure you do not rev it high until warmed up. Also, I never drive mine in auto and always put it in sport immediately upon starting.

It protects the clutch too - mine is pretty new, so I was a bit paranoid! I have just bought a gran cabrio from Richard Grace and will be selling my 4200CC, when I finally can be bothered to get it out of the garage and clean it. Need the garage space!

If the pis has been set quite agressive or a little too agressive then when cold you could get judder and lurchy changes until it had warmed up.

Quick test without diagnostics from cold have it on a flat surface and engage 1st without touching the loud peddle. If it starts to creep forwards the PIS setting is too tight and needs backing off a little.

That makes sense..Matt at Sportsitalia said he had set mine quite aggressive - can’t remember details but would 1.65 or 1.7 make any sense? I could be making it all up though, as I’m clueless on all that techie stuff!

Sounds like a possible cause. I'll explore when I next see the car! Thanks for the feedback :)

In the Strad and my previous MC shift it could be jerky initially if I started it “normally” but just turning the key, but if I turned the ignition on and let it go through it’s check routine and then fired up, it’s never jerky.

Auto is fine on gt. I don't use it but there is no issue with using it.

I always let my cars go through their check routine - hopefully I'm not wasting my time - and it makes my Spyder a lousy get away car!

It was a tip I was given early in my ownership, get in - turn on ignition - put on seatbelt - start car (car goes through check whilst I am putting on the seatbelt)

Had mine out yesterday for the first time in about 3 months and had a bit of shudder when pulling away while the gear box was cold but disappeared once it had warmed up. It's done <10,000 miles so I'm not too worried.

I always wait for the lights to go out before starting as well.
