Thanks to you 2 lads for your replies the amount in the bottom was about 1mm is this about normal
Great thanks a lot will sleep better now the reason I changed filter and oil is I get no drive when car has been stood have to leave it running for about 5 mins before I get any drive changing oil and filters hasnt made any difference any ideas
Try selecting 1st gear manually, if that works it's the sprag clutch.
Keith i think if either of the sprag clutches fail no amount of warming up or running of engine is going to make them work. They just fail to grip and that's and end to it.
You are most likely right Tony, but looking at the cam mechanism that operates the 1st gear sprag I just thought it could be sticking.
cleaning them in jizer tank can make one lock up that wasnt (sticking),and so presumably fresh oil will as oil has high detergent qualities,how log that lasts in p38s is something i have no experience as often whole unit is loose and beyond sticking up in classics and disco 200 and 300 would often work again fine
Yeah your right James. They can be bloody finicky things to play with. Specially if you've never seen inside one before. You only need a knats whisker in some to screw them up, others seem to work fine full of ****.
Just changed the oil for the third time and this time I dropped the sump and fitted a new filter. Not a lot of **** in the bottom but a thin coat of a sort of grey slime. It's made a little difference to the dodgy changes, 1st to 2nd is now normal but 2nd to 3rd is still accompanied by a burst of revs. So it looks like the box will have to come out. Can't make up my mind whether to use the one out of my spares dog with 162K on it or to go for a re-con from Ashcrofts. Will have to decide soon.
Looks a bloody great lump to get out, any tips welcome, like is it better to take the transfer box off first and then the box or hit it all in one lump?
The burst of revs is caused by one clutch letting go and the next one not acting quickly enough. Changing from 2nd to 3rd, clutch 6 disengages and clutch 5 engages. That is supposed to happen simultaniously but there is obviously a pause occuring. Still say you have a sticky valve block.
