Hey now, you can never have too many spares.

Jonesy, if your input gear is not cross drilled I can do it for you, but it would need to be this week since my TechShop membership is about to run out and I don't plan on renewing it.

the TC is good - thanks Charles - it has a cross drilled input gear.

Issue now is a gearbox/tranny with the right suffix etc...guess I should have done research or asked folks first - but I couldn't find info on the board. At least now we have it.

Some info here: Ashcroft Transmissions

Quote:
The LT77 was introduced to the Landrover range in approx 1983 with the suffix 'D' box and was developed over the years to the suffix 'H' which was last used in 1994.

The 'D' and 'E' are very similar the only difference being the reverse gear was a little fatter in the E, When they went from 'E' to 'F' larger layshaft bearings were used.

The 'G' was further improved by all the gear teeth including the pinion getting approx 20% thicker. Also a much wider pump was used to increase the lubrication and cope with the fact that some of the LT77's were now being supplied oil cooled, ie V8 NAS 90, 3.9 RR Classic and the 3.5 EFI Discos.

The 'H' (termed the LT 77S) was the same as the 'G' in terms of strength but used a different synchro set up called the'Double Synchro', In reality it didn't work much better.
The other fun thing to consider is the prefix as that affects the gearing... You have a 51A there which has extra low first and second.

Land Rover Gear FAQ

The reality is that the 200TDI works best with the boxes that came with the engines, "56A" and "H" and a 1.4 t. case. Strong enough and a better 5th gear for the highway. The other "good" option is the 51A box as long as it is a later suffix, especially for the off roader type, but you do lose the highway gearing unless you go to a 1.2 transfer case. (This is what I have 51A/G/1.2)

So, anyone converting to a 200TDI, get the damn box that was with the engine....

It looks like the one in it - that failed - was a 56A, that was also rebuilt by Ashcroft.

Oh, I see that now. Well get that one rebuilt then, or if you feel rich get a short R380 as they have the same gear ratios.

What exactly is wrong with the current box?

Hahaha

------ Follow up post added July 4th, 2015 02:27 PM ------

I think my plan will be something like this:

Take the TCase off the D suffix one I got from Newman, and put that gearbox in the Defender and mate it to the 1.4 TC in the truck then drive it

Send the better gearbox in it currently to get refurb'd then when that comes back, replace the D suffix one which I hope will last long enough.

Alternatively, I send the newly acquired one to get some refurb'd work done on it but believe that will be throwing money away.

So that's the plan right now.

I need the swap to be done in one day so I will begin acquiring all the needed crap so that can happen.

Except that sounds like a lot of work to swap it twice. Where are you sending it to get refurbished? Can you not pay a core fee and send yours after and get it refunded? If it's from the UK I think shipping would kill the deal for sending a core.

And you can't make room in the garage for this?

A 1.6? I struggle with a 1.4 being too low geared, depending what engine you have and tyre size, but I find the 1.2 Discovery Tbox to make a Defender just little bit more civilised, just a little though. A 19j will struggle with a 1.2, but a 300tdi should be ok unless your running massive tyres.

I'd run the d till it dies which has been many years in my experience (actually still going since 2009) then and only then swap in the rebuilt l77s.

In my life the following has held true of boat and rover parts. If you have the new replacement, the suspect part never dies.

JEEZ....turning into a PITA.

So I found a guy in Atlanta that does reconditioned gearboxes - Land Rover Defender/Discovery gear box repairs | Woodstock | eBay Classifieds (Kijiji) | 35737073
His name is Mark Storey - anyone had any experiences with him? He wants $2K for a rebuilt one - shipped to me.

Also here is my gearbox serial number - the receipt from Ashcroft shows a rebuild (matches the stamp on serial #) and it says LT77 "S" suffix which would have a transmission oil cooler on it. I think this is the "best" LT77 for a 200TDi from what I have seen.

Dave Ashcroft doesn't have records going back that far, but I asked him for any information he has on it.

Isn't ordering a 77S unit and swallowing the shipping and core charge well under two-grand?

445(unit cost)+200(whore charge)+200(shipping to South Riding)=845*1.6ish = $1350

And 350 pounds more to get a stumpy R380 (995 versus 645) is worth thinking about, giving around $1900 total. Sell the broken box for a couple hundred for someone to rebuild.

What oil have you been running?

Yeah guys now you see my dilemma? Coupla grand versus putting a suffix D one in it and running with it - as Doug said he has had one since 2009 against a 200TDi...

shit.

I have a Suffix D in my 110 with a 200tdi and a 1.2 disco Tcase for about 55k

Runs great and shifts great. I use Redline MTL and it significantly improved shifts.


Also if you are pulling the trans keep in mind you may have to do a pivot arm, clutch and related seals once you get it apart
