Slight crunch going into 3rd gear

[Domvalver]

Title says it all really, 172 phase 1, when I change down into 3rd to over take it seems a bit tight, a bit of a crunch. Ive played about with gear changes but it seems relevant to revs as in if I allow it to slow down it goes in fine. Car has done 58k, any ideas?

Welcome to the world of crap RS gearbox's. Syncro wesh worn is the most liekly cause.

I got 130k out of mine, so IMO they aren't that weak!

Dont abuse it and there fine...

 

[Domvalver]

I was wondering if it might be that except it had only done 43k when I got it and by the look of all the receipts had been wrapped in cotton wool.

 

[Tony Hunter]

Most of them will if you rush them.

 

[Domvalver]

yeah not a big issue really, I find if im in 5th pootling along behind something I will just go into 4th then 3rd while the clutch is down and that either gives it more time or a slicker movement

mines just started doing it a little, not surprising tbh

sync mesh on its way out probably

Oddly 3rd is my best gear, it's just the rest.

80k and on second box here. JC5 doesn't like being rushed at all

What's the box in a 1.6? Mine's a bit crunchy at 74k. Wouldn't surprise me if it was ragged around by the previous owner.

Not the JC5.

The JC5's ive driven (or used) werent THAT bad really. I mean it was no BMW or Honda but by all means it was more than operable but like people say not for rushing.

If you want to experience a bad gearbox, try using the TL4 from the 197 or Clio GT, now that is s**t, my synchro has gone into 3rd and have it booked in for replacement. Im not sure if the 200 uses the same box.

My 3rd's always been a bugger for down changes, even with some blipped throttle action.

How much to get the box refreshed (rebuilt). Just rough prices.

I just blip mine Into third and it's fine. Can be a b**ch when cold though. Is there a rebuild with a LSD option anywhere? What's the best LSD for a 172?

my 3rd gear exactly the same, has anyone resolved this??

 

[Silent_Scone]

syncro rebuild or knackered dog bone mount 9 times out of 10. been covered loads on here

 

[mr.valver]

Ktec Engine/gearbox mount and Powerflex dog bone on my car.

Did help but still iffy.

Yeah done all this, it does it under heavy acceleration, shifting from 2nd to 3rd, ill see if double clutching works? covered 70000 now, how much does a synchro rebuild cost :S

my car has now 145.000 km, and i'm the third owner, and still EVERY gear change is smooth, no cruches, creaks etc.

They aint smooth new, so don't see how that can be.

i don't know how the gearbox was when it had 0 km, but now with 145.000 km it goes in every gear without any problem, no matter hig-low revs, upshift-downshift.
the gearbox oil was changed from first and second owner every 30.000 km (Tranself TRX 75w80) i continued that, the complete clutch set was on 120.000 km.
as i said no crunching gear change or anything else.
