is it all gears or just an individual 1 or 2, is it worst when you are traveling faster or not?

Is that every gear change?

I had the nasty experience of coming off a motorway run and being unable to select a gear without brute force. This went on for a couple of days and then it just became a bit of a shove to get it into gear. I ought to do something about it but the gearbox splines are shot so it needs a new box sometime but I can't afford it now. So, after 6 months I'm still making slow cchanges and it's still going into gear.

Maybe you should wait a short while before doing anything radical?

I fitted the difflock oils 2 or 3 thousand miles before this happened but I am certain that's unrelated.

I'm not at all convinced they make any difference at all except to your bank balance.

Subjectively after filling the transfer box the transmission felt smoother but I don't think it helped the gearbox at all.

It's been happening now for a couple of weeks.  At first it was only when I changed down from 3rd to 2nd gear, now it's started when I change from 1st to 2nd.  Definately seems to be 2nd gear that's playing up! Yesterday I had to stop as I couldn't get it into 2nd gear at all when I started off!

My Disco is an 'L' reg, 2.5tdi if that helps anyone!

Any help appreciated as being a 'girlie' I don't know much about it!

I believe this is a classic Disco problem. The selection of 2nd gear in some way wears over teh years. You may find the difflock oils help equally when was the gearbox oil last changed?

Otherwsie I thinks it's new gearbox time!

You may find that changing gear more slowly helps or double declutching. Taking it slow works for me.

I don't think Discos know if they're being driven by ladies though so that bit probably doesn't matter.

another thing , alot of disco gearboxes have auto trans fluid, which you could easily check. its red in colour .whilst its ok to use mtf is alot better, got a full spec sheet on it somewhere. iff ya need it give us a shout i'll try and dig it out. alan.....on the note of diflocks oil it was the price that made me think twice about it.
