Thread: R380 Gearbox Fitment to 1994 Disco 3.9 V8

What month is it?

My 2/94 3.9 V8 Disco has an R380 gearbox already.

Does your 3.9 have the serpentine belt or the multiple V belts?

The 94 D1 updates are all R380. Late 93/early 94 DI 3.9s (pre updates - have orange 3.9 decals) have LT77.

As to the original question - dunno but I assume it can be done if you get the complete box/bell housing/clutch etc.

Vehicle is pre-update model with the orange decals it has LT77S with reverse being up and to the right.

I had one of these for a little while - hit reverse at the traffic lights a few times instead of first. For drivability, the R380 is much better.

It should be an easy swap. A mate fitted an R380 into his fathers 86 RR that had the LT77 box easily enough.
He also fitted a Disco transfer case at the same time but that shouldn't make a difference.

Obviously, make sure you use an R380 from a V8.

Is the lt77 belhousing the same as the r380 belhousing ?????? if so can a r380 box bolt up to a lt77 housing or not ?????
