Rebuilding LT77 Trans...

When I bought my 110 it already had an R380 installed, but the PO had saved the LT77 and it's bellhousing and included them with the truck. IIRC he said that one of (I think 2nd gear) the syncros was bad and that is why he replaced it. Anyway, since I've got it layin' here I figured I might rebuild it when I have some spare time and I'll either keep it as a replacement or sell it and pocket a little money. My question is, have any of you done this and how difficult is it? Also, where can you buy a complete rebuild kit reasonably? Finally, what do you think a rebuilt LT77 with bellhousing and shift knob is worth?

Thanks guys!

Well, the only reason to rebuild it if I sell it was for the learning exp. and b/c I figure it is worth more if its rebuilt. Yeah, the trans is in Winnetka right now which you probably know is just south of Lake Forest. What do you think its worth as it sits?

Forgive me if this is an ignorant question, but what are the advantages or disadvantages of the LT77? It seems that most 110's have been converted to the R380. I was talking to the PO of my friend's 110 who had converted his but held that the LT77 was actually a better trans. Were the LT77's ever installed in NAS D90's or just 110's? I am planning to sell my 110 as soon as I finish the restoration b/c I really am looking for a 90. (I know, I'm backwards of many on here! haha)

Anyway, the only reason to keep the LT77 is to include it with the sale of the 110, or if it really is a better trans and fits, I would keep it as a backup for my future 90.

I guess guys like the R 380 cuz you can go forward to reverse easy. I don't know which is better IMHO they are both good. My cuzn's 94 90 has a r380 & its an early one. My syncros have been going for a while now & one of these days I will rebuild it but I have a lot of irons in the fire.

Andrew - just FYI, I personally would never touch a trans that wasnt rebuilt by a professional - or at least I wouldnt pay much for it. I agree that rebuilding it for your own fun/learning is the best possible outcome and you should just keep it with the truck.

Follow-up Post:

But there is still a good chance of messing it up. If you want it done right, send it to Rob D.

The '94 and I think the '95s had the LT77s. I thought the 110s had the LT85s

Tyler, nas 110's came with 77's I may be wrong but I think earlier 110's were 85's

My cousins 94 has a 380 & I don't think he had it replaced??

110s and early 94's had the lt77 (in fact, mine still does, and it's in good shape), though it was VERY common for them to be swapped out for the R380. My understanding is that it was due to customer complaints about the notchiness and slower shifting needed in the lt77.

Andrew, I'm with you, I'd try rebuilding it for the experience.

Yeah, I've rebuilt a tractor trans/gearbox and a friend of mine went to VW training to rebuild VW Trans' so I am sure he can help me out if need be.

Hmm.. didn't know that about the 110s. After breaking two LT77 I swapped in an R380. Its supposed to be a stronger transmission. The LT77 comes in three parts the R380 is one piece.
