Swap LT77 with R380

Trailstar · Oct 10, 2018

Just doing a bit of research, what would be involved in swapping out a lt77 for r380 gearbox?
Any changes in crossmembers and will it work with the existing transfer case?
It's in a 1984 range rover classic so it's the long stick version, and suffix d, so weakest of the lt77s...

Thanks!

defender, but in needs to be v8 if fitting a v8,though disco or rrc box can be used if you get and ashcrofts selector rail converter and defender g box top selector housing etc

Ok, the engine in the range rover is the original 3.5, so it will need to be that...

Just seen this here which could mean I can use a v8 discovery r380 or not? Because if I remember correctly there is two different types of bellhousing? One is different for diesel engines?

Thanks for your help by the way, much appreciated

yes as ive added to my previous post, there are many different bell housings and input shafts to fit the numerous engines lr used, youd be best with disco 1 box and bell housing

Also what are Ashcrofts rebuilt gearboxes like? Worth the money or vastly overpriced?!

Will be importing it to NZ with a load of other stuff from them and a few other companies if I do get it
