Serious help needed.

Erm how else do I describe it. If you pul away in low range does yours accelerate really quickly in 1st gear? With mine it is like a clutch slipping as the engine revs to 3k with a very slow acceleration and then once at 3k revs it changes up through all 4 gears really quickly and off I go quickly too. Mine is an auto if thats a vital bit of the puzzle!

Check all the cheap stuff first. Vibes through the transmission are normally props, ujs etc. Whip the props off for a propper look at the uj's and the rubber ring coupling, 25min job maximum. Remember to pop mark the diff and prop flange to ensure you get them back on in the right place.
Mines an auto too, had assumed yours was. Mines a V8 though so probably not comparable. Check the fluids and discount gearbox probs till you've checked everything else. G

Have to say mate, your description makes it sound like the gearbox, especially as you describe it as clutch slip. The transfer box has no slipable components... unless it's a borg warner with viscous coupling but that would tend to lock rather than slip.
Do you have the same symptom in high range?

muddyjames:
When in high range it does sometimes rev really high then thump into the next gear but that tends to be when cold and from 1st to 2nd.
I put red ex in the tank recently and that has made the gear changes alot smoother and it hasnt done it very often since then.
I have just had another crawl underneath and there is ep90 leaking out of the rear diff. How do I explain where it is leaking from :? Here it goes!!!! Where the drive shaft bolts onto the diff there is a small groove right at the drive shaft end. it is leaking from there. I have very poor photos if they may help.
Im guessing auto boxes will make a disco this old a right off? If it is the gear box :?
Skibum346:
Sounds like the pinion oil seal, designed to let the shaft driven by the propshaft enter the diff... without your black gold leaking out. Again, it's a relatively simple diy fix.
If it's your gearbox and your going to pay a professional, I'd suggest it will be pretty expensive. However, lot's of members change gearboxes with monotonous regularity so there is hope.
If it is the gearboxz, your options are (as I see it):
Brand new gearbox installed by a professional
Reconditioned gearbox installed by a professional
Reconditioned gearbox installed by knowledgable person
eBay special installed by knowledgable person
For gearbox costs check out Ashcrofts for a guide price or any of the other gearbox specialists in the landy mags. There is one in Rugby (Wards?) and a few around Birmingham.
I think you'd be best to get a decent garage to investigate and diagnose (I'd recomend Douglass Motors in Wolston near Rugby. A bit far perhaps but helpful & trustworthy!
With a decent diagnosis your options will be much clearer.
Incidently, I have heard tell of autoboxes behaving like new after a fluid & filter change (gearbox not engine fluid & filters of course!)
Hope all works out for you.
muddyjames:
If the oil has run out in the rear axle then will that make it vibrate like it is? I only had the oil changed in those before xmas and I have done about 1000-2000 miles since then :?
I am tighter than a ducks ar** so will investigate the cheap routes first.
If I was to buy an ebay special that had a broken manaul gearbox with a good transfer box would the transfer box fit my auto box?
I think I will have to just keep pestering my local landy mechanic for a proper diagnosis (he is on this forum too. Alan if your looking get in touch please :wink: )
