Hello . I have an issue with my focus 1.8 16v IB5 gearbox. When i put on first and release the clutch there's a strange rattling noise from the gearbox in the early RPM. After 1500 it's gone and when i put in second it shows again around 1000-1500 RPM and disappears. Theres no problem with upper gears or when cruising or pushing it to the limit. It's like a diesel rattle when i go and when i push the pedal it's gone. So i'm curious what could that be? Can you help me ?

 

could be the mainshaft bearing on its way out thats what mine sounded like before it failed

 

So it sound's like a new gearbox or?!
Should i look for MTX75 or it's not suitable for 1.8 blacktop...
The sound is from a year or so...
Tonight I was driving... and stopped for a short beer.With my windows down and no cars on the street i heard i quite clear when i released the clutch.
I would like to hear other opinions too
Thanks

 

does the sound go away when the clutch is pressed when car is stationary or moving? if so it could just be the clutch release bearing

 

sounds pretty much like the backlash in the dual mass flywheel but i don't think they have them, i know the diesels do + the st170.

I think its a case of box off and have a look,
I don't know my modern fords that well however i think its probably input bearing

 

Hi again

When the car is stationary on neutral... there's no sound just the engine revs.
It's from the gearbox for sure.When the clutch pedal is pressed there's no sound.
When i released the clutch when it contacts i heard something like a "click" then it rattles a bit and goes away as i speed up .
On first and second there's a slight rattle up to 1500 RPMs or so.
At first i thought that it's the release bearing but I wanted your opinion.

 

one or the other, release bearing or 1st motion shaft bearing, either way the box has to come out, so take it out and look at the bearing first then if its fine (always put a new clutch kit on if the box is out) you will be looking towards the box. i would run it till it gets worse to make double sure, a secondhand box will not be dear.

 

So mate tell me, what do you mean by "second hand box .... no dear".
You want to tell me that i need to repair this one?
And can you tell me what are the possibilities for a MTX75.Is it a straight job or no?
In my opinion the real focus gearbox is the MTX75 but i'm not sure if the gear ratios would be suitable for 1.8
You're right the gearbox will come off for sure but I still wonder which way to go .. MTX75 or repair the IB5.I'm sceptic about the second hand too.
