Loss of drive.

Bern there was quite a discussion about that sat night, and the out come is i think that nick will be investigating this using the old box to strip down and have a look.

Was this the conversation that IT specialist Wouter talked about machining a shaft after it had been hardened and insisted he was right? After all what does Vicky know, she is only a woman!!!!

I will let Wouter explain what it is that Vicky does for a living

[Wodjno]

What is the original shaft made from ??

[ariddell]

Playdoh by the looks of it.....

That's quite impressively snapped, good going!

[Wodjno]

It looks like its been a progressive weakening of the shaft.. I cant see how suddenly it can just go .. I mean a lot more power than what Nicks running has been put throught those shafts and they haven't gone bang.. It has been twisting up for quite some time now i reckon. But it got to the point where enough was enough..

I agree with this. I think that the thumping I got into 4th occaisonally was the problem. However, I would like to have a chat with Graham the next time I see him - I don't know how bad his shaft got or what he had put it through before it went.

I would also guess that all of us who give the box a bit of abuse have twisted these shafts to some extent. Unfortunately, it is not all that easy to find out!

So seems like a good idea then to try and source someone to manufacture some out of a higher grade material.
Regarding what Graham has put is through. I'm sure i remember a conversation with him that mentioned 1.3 bar.

Gear change is getting better but I am having some shudder issues. I am desperately hoping that the brain sorts it all out soon!

Keep Chugging.. It'll smooth out .. Around 600miles normally in my car.. Although each car will be different .

[psbarham]

what sort of shudder is it ?

[richy rich]

does it do it in tip as well as D
have you checked the atf again.
i had to much in and it didn't work properly check out my thread when i changed my box.

[Nick Mann]

The shudder I think is to do with lock-up in 4th/5th. At low revs on low to medium throttle.

I haven't yet re-checked my ATF. I will do next time I am parked on the flat!

[richy rich]

nick this is from my thread
OK Ive had a few small prob with my box.
1 when going down one particular road its down hill just after a speed hump
the car jumped a bit.
2 gear changes a bit funny cant explain it well
3 slight smell of atf burning (come to the conclusion only oil that spilt on box).

Ive just checked atf i had to much in it drained 1/2l off
and steam cleaned engine

all working fine now, even on hill descent on a hill near me it it is a 15% down hill normally its in 4th and feels like its running away, today went in to 4th then after 2-3 sec went in to 3rd and held the car down the hill.
also prob 1&2 gone.

I have had that shudder since i got my car.. If you are at lowish revs in 4th or 5th and you have it in Tip and excellerate fairly hard you feel a shudder.. The more you get up the rev range the less you fell it.. So it's obviously load related. But i've been running it like that now for nearly 2 years.. It was not noticeable before i put my boost controller on though.. Is this what your getting Nick .
