Any help .

My boyfriend has a fiat panda 1.2 and recently it's been jumping out of 3rd gear and won't go into 4th .
Now he's checked both cables and they are fine . Any advice would be welcome . Thanks

Re: Any help .

Hi.

Jumping out of gear.. not great ..

Is that when lifting off the throttle?

Re: Any help .

Jumping out of gear usually means it didn't fully engage.
Either the selector fork is well worn, so losing movement, or the gears have too much movement along the shaft (should be miniscule).
Selector fork wear is caused by every owner holding the gear lever much of the time, instead of the steering wheel, but modern oils and gearboxes are much less prone to this wear.
Excess play option could be caused by the nut on the end of the gear shaft, at 5th gear, coming loose. This can be checked relatively easily by removing the gearbox end cover, under the battery. Time for oil up the sleeve. If it is loose, tightening it may fix the issue, if damage is not too great. There have been a few reports of these nuts becoming loose over the last few years.
Tightening it to the correct torque is a challenge. When building a gearbox this is done on the bench, and two gears are selected together to lock the shafts. Might be possible if the selector mechanism is removed from the top if it brings the interlock mechanism with it. Might work with it in gear, both wheels on the ground and someone stood on the brake, but access then is difficult. If heaving to tighten a nut whilst under the car, ensure it is very well supported.

Re: Any help .

I think the damage might be already done

To an extent.. almost certainly..

But: well worth checking over the basics.

How old ( what registration year..) is this panda ?

Is this a new problem..on a car he has had for a while.. or a recent purchase?

Re: Any help .

Don't drive it further until diagnosed/fixed.
Very likely to be the nut on the end of the shaft.
The attached file is from the Fiat workshop manual.
Whilst htis shows the gearbox out of the car, and stood upright, the end cover can be removed from under the car. It then appears that by removing the 5th gear selector bolt, 5th gear can be engaged at the same time as any other gear (using the lever), which locks the gears, so that the nut can be undone or tightened.

If only the left side of the car is raised, this might be possible with little oil loss.
