Without seeing its hard to tell for certain. Put in normal drive (dont use sport). Is there a diffrence in forward and reverse? From what you discribed it could be a problem with the clutch pack. If not then the pump. If clutch pack , when you drained gearbox first time was there any black bits in fluid. A common way to bugger the gearbox is if it has been towed say after an accident.

forward and reverse seems to be the same.no drive whatsoever.the fluid looked clean and bright red when it came out but does look much darker in the bowl I caught it in which is white in colour

sorry, not sure about the original fluid, as when I got the gearbox it had already been drained

 

Just to be clear. You put in gearbox. Correct oil level. Adjusted gear cable correctly. Conected multi pin conector and other sensors. Ran on the ground into D and R and no movement even when throtle pressed. There should be engine note change as gear selected. The D or R came up on the dash display and the gealever base. If so it does sound like you have a dud.

done all this except didn't put on ground .still on axle stands with wheels off.when I select D or R the engine revs go up and down slightly but no drive other than one of the hubs turn slowly when you give it a rev but you can stop this with your hand.but even in reverse, the hub still slowly goes forward. (the same as if you jack up a manual and the wheel turns slightly even though in neutral). thanks

 

Where abouts are you? The piston spring sounds like the clutch retaining ring. Def sounds like its got to come out. You should have a good clutch pack from the gearbox with the broken belt.

im in Stevenston, Ayrshire , Scotland. ile prob strip it back out tomorrow or Friday. your advice is very much appreciated thanks.

 

To change the clutch pack you will need to split the gearbox. Nothing too difficult but be carfull with the maiting surfaces as there is no gaskit just sealent. Also there is a linking bar inside that needs to be undone prior to full seperation. Practice on your one with the broken belt. As long as you make sure to note the order and placement of the components you should not have too much dificulty in swaping over the clutch packs. They look very much like motorbike wet clutch ones. Check for wear, when they are worn they will be smooth and continus.

ive opened both boxes up, first one as expected more bits of bands fell out.clutches though appear to be in good condition with no signs of wear. the 2nd box ive just removed from car ive opened and found another piece of met to match the pieces already found.does look like retaining ring but not as thick as the ones that hold in the clutch assemblies, they are still in place.what I have found and believe to be strange is the most of the clutch plates are BONE DRY.the particulary dry ones showing sighs of little heat cracks on the ferodo material. could this be signs of pump failure?.i know the gearbox may have been idle for some period of time before I received it and fitted it, but I had the engine running best part of hour or so as I had to bleed the coolant system on the car and check coolant fans were working at running temp and also recheck cvt fluid level when warm.your thought would be appreciated. im going to remove clutch packs to see if I can find where this broken ring has come from. thanks again stevie

 

was the belt covered with oil? Remember if you remove the pump you will need new o rings. Also be carefull of the oil pickup as i have seen this flatterned .
