LT77S to R380 in 94?

From what I have read, in late 1994 the LT77S was switched out to the R380. Does anyone know what NAS truck number started with the improved R380? I am thinking that I may be open to a 94 if it had the R380...really the only reason why I was excluding 94 was of the LT77S.

Most of the LT77's were swapped under warranty, so realistically, there would be very few that did not get swapped.

Well that is good info, I didn't know they were replaced under warranty. How would I know when looking at one?

The reverse on the LT77 is on the left and the r380 is in the right... Or visa-versa. Can't remember.

Just Ask the owner where reverse is before you go look at it.

But they still have trailer lights and snap tops

And I love it- although waiting until December to put the Tickford back on wasn't the brightest idea...

Oh yeah- #282 r380 via warranty.

Like Matt, I've been looking at Defenders. If I found a very nice low mileage 94 that still had the original LT77, should I pass it up and wait to find one with a R380?

No - not unless you've driven the LT77 and find the experience to be unenjoyable. The LT77 was a voluntary recall for those who did not like the feel of the LT77.

No. Most trucks have the R380 by now but if you find a truck with a LT77 it's not a big deal. Those trannies work fine. I know a guy with a 94 that had his LT77 shit the bed and he insisted it be replaced with another LT77. You need to look at the truck as a whole.

Not really a recall. More of if you complained of any issue with the lt77 they gave you a r380.

Finding a 94 that still has the LT77 is rare.

I don't see too big of an issue with them as long as you shift slowly (as you should do with the R380 too).

#58 had the LT77 with 260K on the clock and 2nd shit the bed about 270K (it was already going when I bought the truck and this tranny was treated gently with all synthetics its whole life). The next LT77 I picked up had the same problem. I would run from that tranny if 2nd feels funky - meaning you have to slow the RPMs to shift or it is crunchy. I wouldn't rule out looking at the 94s as the early 94s you get an internal role cage support on top of each rear wheel well (in the inside) and if it has an LT77 negotiate price as it is not a matter of if but when it will crap out.

I did that when I blew up the original.

As I understand it, the problem with the LT77s wasn't caused by the transmission at all but was caused by the transfercase. Lack of lubrication on the internal portion of the transfercase input gear caused premature wear on the transmission mainshaft. When trucks went in for the repair, the transmissions were replaced by the R380 which was by then in production.

What is it about the 'feel' of the LT77 that people didn't like?

Sorry to ask so many questions. I've always been a Series Land Rover guy - have owned a 63, 69, & 71 IIA all SWB, and currently have a SIII Lightweight. I also have a 68 Camaro with its original 4-speed, so I am used to older manual transmissions. Maybe the LT77 would feel just fine to me.

Yeah, the problem is that the vehicle has less than 20k miles and is rust free. I talked to the seller and I don't get the feeling they are willing to move on price, which is quite high.

Is it out in LA? I've never driven one with an LT77 but you already drive a Series so you shouldn't be worried about it.

I have a "new" Lt77s behind my 4.6 in my 110 and prefer it over the R380 in the D90. The shifter throw is shorter and just feels tighter. Plus, after driving the Series for so many years I got used to reverse next to first. It's that way in my Mini Cooper S too.
