Mind you your 630 has a ZF4hp24 in it, same as my 4.6 with a different ECU ;)

So maybe the ZF can be built accordingly ;)

Different ecu for engine, not sure a 24 would cope with that much more abuse though, however it was built.

Yep hard to believe but it is a standard HP24 with a different TCM/Map.

The HP24 is capable of great imput torque, the TQ is different however - the stall is slightly higher. ;)

Not sure about change in TCM only different ecu

I didn’t think anybody had actually cracked the RR TCM yet?

I'm guessing 'Finch managed to do it, according to sourses it just has a different Transmission control module Map..

To enhance gearchanges, and improve shift time.
 
Adaptor plate SBC to ZF box are readily available, probably to the R380 too? But I believe manual might be border line don’ know.

So from there back all the same 4x4.

Although I would imagine that in a defender would certainly be a handful :D

Think a 6.3 would kill a manual box. Henry would probably know the figures.
 
6.3 small block hand built in 'Finch spec produces 400hp and 619nm of torque, which would shred the manual ;) Which is rated for 380nm hence the name R380.

The ZF4hp24 is capable of taking a great amount of input torque so long as it's cared for ;)

A few Demonstrator 4.6's were produced with the R380, but the 'box was shredded due to the torque!!..

Not the strongest box in reality..
