Thread: Problems with fourth gear in R380

If it's only 4th, the bearing between the mainshaft & input shaft might have given up the ghost.

When you select 4th, you're joining these shafts together (1:1 ratio) & the bearing failure can cause misalignment problems (hence selection problems).

that also has some other minor symptoms.....

like whining in 3rd and 3rd gear becoming a little hit and miss.

check the oil. lots of brassy stuff means youve burred over the dogs on the baulk ring of the syncro unit silver metally flakes means a bearing.

the first you can deal with if you double clutch just right. the latter is doom for your box.

Thanks mate, I'll do that. Doom for my box would be rather disappointing at only about 170000km.

I know a bloke who will sell an R380 for a TDI for $300 in Brisbane.
I can provide his email if you require it. I don't know if it was out of a disco or defender though-nor does he. He says it is an LT77 from a V8 Disco.

OK, I drained the oil and there are lots of silvery bits. This is what the drain plug looked like:

...And these are the same bits along with what I strained out of the oil:



So what now? Am I doing further damage if I drive it? Or is the damage already done? The box feels and sounds normal apart from fourth which is difficult to engage, although if I double clutch and get it just right it slips in easily. What's happened in there?

So is it an R380 or LT77, for TDI or V8?

Were it mine, I'd get comfortable walking shoes and fix the problem before driving it. That looks bad.
