Worth rebuilding an LT77?

PO destroyed the transmission in the rig so had it replaced. He kept the wrecked trans with plans to rebuild it. It appears he opened it, realized he was in way over his head, and closed it back up. The main shaft looks pretty beat and I think he said 3rd gear was missing. I pulled the plug and found what looks like most of 3rd gear.


So is this worth anything? Either as a core for someone, or a project worth hanging on to?

Do you have an LT77 today? If not, think I'd sell it to clear it out as a core for someone else to use as they see fit.
If you still have an LT77, then I'd rebuild it or send it out to be rebuilt.

An Ashcroft rebuilt LT77 is about $550 plus shipping. That makes rebuilding that one awfully unattractive.

What is the suffix? If it is an early one, it is not worth rebuilding. A later one possibly. That is not much metal on the plug.

Rebuilding an LT77 is not a binary operation. It's not a case of "not rebuilt" vs "rebuilt". If you have an LT77 where all the internals have shattered, the shift forks and synchros have been beaten into powder, and hardened steel slivers are shoved into every bearing and nook, rebuilding that is almost impossible.

If you have an LT77 with worn bearings, seals, and worn synchros, it's an easy rebuild.

An early LT77 is a fine transmission. I rebuilt mine (required new synchros, new shift keys, new oil pump, bearings, seals, and a new 3-4 shift fork.)

If only a few parts need to be replaced on an early LT77, then save it.

I sell transmission cores for $99 when someone needs one, but the Ashcroft units are sound and reliable.
Imagine having to pull one you rebuilt several times if it is not squared away and you are not a transmission rebuilder in the first place.
Peace of mind with a thinner wallet is the only way to go in my opinion.
Junk transmissions are easy to find.

I was told there is a rebuilt LT77 with 13k in the truck now. The busted trans is just taking up space right now. Unless I was lied to about the one in the truck, I can't foresee needing it anytime soon.

This one has an F suffix. The top plate was removed an a few gears are visible. It looks pretty good from the limited opening. That input shaft scares me though.

A suffix F LT77 isn't really worth rebuilding. It's really only worth giving away to someone else who has a Suffix F to part together with theirs and save costs. Ashcroft gets lots of exposure in landrover circles, but there are fellows who rebuild them in North America too. The 77 isn't bad, but why pay the same or more to rebuild one as you would a later R380? Not sensible.

In my opinion an F is worth keeping. It is a decently strong box and the casing is specific to that suffix. It can be useful to someone looking to fix an F.
