How to identify an R380 transmission?

I'm going to look at a 1994 D90 tomorrow with only 12,000 miles on the clock. I'm worried that it may not have been updated with the new R380 transmission. I know it could be replaced under warranty, but since the truck has so few miles, I'm not sure if that would have been done. I don't know when it was built either, since I know at some point they started putting them in the 94's. Is there a way I can look somewhere to see if it has it? Or if I find the build date, is there a specific date where anywhere after would be ok?

Thanks in advance,
Chris Snyder

Look at the shifter knob. If reverse is all the way left and down, it is the R380.

to clarify, reverse is down and on the right (passenger side) if you are sitting in the drivers seat.

I am. I know what they paid for it (they bought it from this forum). We'll see how it goes.

Reverse in the LT-77 is up and left, next to 1st gear.

The LT-77 also had a couple updates to it that corrected the major problems, and down the road an R-380 swap is pretty simple anyways. So don't let it steer you away if it has the 'wrong' transmission and it's a good deal.

Great. Thanks guys!

Just out of curiosity, what were the major differences between the two? I know the LT-77 was prone to syncro failure, but I don't know if that's it? Why was it so bad?

From what I have seen of the LT-77 and what mechanics say about them they are not that bad.

The R 380's had their problems too. Wear on the transmission output shaft inside the tcase from lack of oiling.

I bet you could get the service history and find out what has been done... if it was done at a LR dealership.

I sold it to a Marine stationed in the D.C. area but he said he was on his way to Camp Pendleton, so I guess it's in sunny SoCal by now. Kind of ironic that it ends up 15 minutes from where I used to live and work.

R380

Check out http://ashcroft-transmissions.co.uk thier site has lots of information on both manual boxes, transfercase and updates.

I ordered a new (not rebuilt) R380, updated transfer case input gear and clutch kit from them last week.

The LT 77 is an ok transmission, just not as good as the R380. The latest manufactured R380 is the L series, which apparently has larger bearings.

The transmission is just about $2000 including air freight to Vancouver. Local dealer wanted $5100!!! or $4100 for parts to rebuild.
