Hi guys and girls

Haven't posted in a while but was hoping someone could help me out.
I have an EF 5ltr auto that seems to be rooted, but I wanna know if there was possible to fix it before forking out for a new v8 box.

In any forward gear it seems to free rev from a standstill or even at a rolling start of around 20kmh. basically if I take off out of the driveway or from the lights it revs for a bit, shudders, makes a honking/whining sound before it actually engages and takes off. I'm hoping that a bit of fluid or replacing the inhibitor switch will fix it but as it gets worse I'm getting worried I may have to replace the box.

I might add too, that, whilst this is the case with the box majority of the time, it does have the odd day or 2 where it seems like a perfectly fine gearbox.

Any help or direction is greatly appreciated.

Cheers
Grant

Silly Question, but have you check the Trans fluid level?

Hi SWC

It has an EL box in it because when I bought the car the gearbox was stuffed and I picked this one up 2nd hand, so it is a sealed unit (no dipstick) and to get the fill plug off is nigh on impossible without a power tool coz the last person to have it off was the tranny mechanic so as yet I haven't been able to check it. Lack of cash also provents me going back to the same fella. I am planning on borrowing an impact driver from a mate soon to attempt getting it off, but I just wanted to see if there was anyone whos had the same problem to see if it may be more than that...

I'm hoping that's all it is coz I have the fluid here ...

Oil level is a good place to start.

Might see if I can get the driver tomorrow and I'll jump on here again after I give it a go. Fingers crossed ..
