I love the P6. My dad had a Lunar Grey (light green) 1973 2000 single-carb automatic (2000SC auto), LAC665L, one of the last-ever 2000's before being superceded by the 2200. It was slightly leisurely but very quiet and comfortable.
There is the P6 club, from Alaska to Australia. See the Rover forum for any information you need. I'm restoring a 2200TC myself, but I'm not a gearbox specialist. As far as I know LT77's came off the SD1's. And it's got ATF in it, so it must be an Auto box. Unless, they are running on the wrong oil.
Hi That's a great video, thank you. I wanted to add in the case of the viewer wanting to attempt this who has maybe got disillusioned because of the amount of special tools required that all is not lost, I just did this same teardown on a Suffix A box with tools available for rental or purchase at autozone in the US, namely 2 bearing pullers, a push pull puller set and a pilot bearing remover for that inside bearing race on the pilot shaft. All in all that was 200 bucks and you can return them. Lets face it not many of us have those Land rover tools or have access. I got right down to the bearing off that is done in the second video. No offense at all but it might be good to see this done with readily available tools, as I know it can be, either in US of UK etc. If you can apply heat and have these tools, you can do this. Cheers
Like I said mate I'm not knocking it these videos are amazing and they help us have a go at it. Without these and the axle videos I dont have any hope of completing what i want to do.
Interesting to see an LT77 from a P6. Definitely need that puller though, and I'd have thought that the nuts and bolts would have been imperial as it was a 70's car. In any case, must have been well cared for as in very good condition. Wonder if the car is Orange?
Hello Mike, I'm Dieter from Germany. This is also a very informative video for me. I am the owner of a Jaguar E-Type Series 2 and bought the same transmission five or six years ago to change my Jag. from the automatic Borg Warner 8 to the five-speed transmission to reduce the speed level in the XK engine. Jaguar has installed these boxes in the XJ 6 Sedan Series 3. That was in the early eighties. It is very rare in the XJ 6 Jag., a kind of blue Mauritius. Where could I get spare parts, seals, etc. if I need something? Best regard‘s, Dieter from Germany
Thanks for a great video. I'm just about to try and remove the rear cover on my TR7 LT77 in order to replace the o ring seal for the selector shaft so this was great to watch. Do you think that "reluctance" of the cover to pull off initially was due to the circlip on the output shaft which retains the speedo gear? It's difficult to see but it looks like the groove might be chamfered to allow the cover to be pulled off bringing the circlip off at the same time?
@@BritannicaRestorations Not to worry! No doubt I'll find out soon! I'll be working under the car with just the back end of the gearbox lowered (car on stands so not much headroom) so just trying to anticipate any snags. 👍
thanks for the video. From my experience it is a good gearbox when you change the gear slowly. I use it on my classic range rover diesel with more than 525000km. It is pleasant to use, not the gearbox that is on my defender td4 from 2012.
Yes, which is why I shy away from products like the slickshift, which makes shorter length for shifting gears, but encourages faster changes. Slow and easy for these LT77/R380
@@BritannicaRestorations You could also say that for the MT82's in the Puma. That is a notchy change, especially first to second, not something you want to rush.
The gearbox looks very similar to the Leyland sherpa gearbox, bad shimming and towing without removing prop can damage box, we didn't have many issues with them, in the Royal mail fleet.
Yes, when you tow these boxes a long distance, the mainshaft is turning, but the layshaft isn't, so there is no drive to the oil pump and nor is that any splash feed! This can wear bearings out quickly !
All LT77s were metric. The LT 77 was never factory fitted to the P6, but was the standard box on SD1s, this is probably were it came from, but could also be a TR7 unit 2nd gear synchro is the weak point.

Dismantling tool... Available in the shop

LT77 was run on ATF
Yes and no, the Rover guys here use Redline MTL and Castrol Syntrans or similar.
Never had an issue with ATF

I have had those LR tools 20 years

Well done!
Great work as allways , thanks for posting.
My pleasure!

Last 2WD on I did was an SD1 - simple gearbox
I wonder why they were OK on 3500 V8's but not so good in Land Rovers?

I really don't know where to get parts - the customer supplied them

To tell you the truth, this was the first I have done and was months ago - I cannot recall

Very different. Got any tips or idea how to strip raptor or bed lining off a landriver defender
Flame thrower - best of luck! Lol!
@@BritannicaRestorations thanks
It look the same as a tr7 5 speed

I don't know - this is what I was told
Bet, AI couldn't do this 😅
