4HP22 differences
I know not exactly Defender related, but can anyone shed some light on this.

Currently helping build up a 110 with V8 + 4HP22.

Come across an issue with the LH gearbox mount - everyone says the manual one fits... it doesn't.

This has shown up there appear to be two versions of the rear extension/output shaft case.

Long extension:

Short extension:

Does anyone know if there is a difference, and why/what for?

FWIW we've currently got the short version, and the manual mount doesn't fit (it's too wide). Concerned this'll cause issues with transfer box in the wrong place, props not fitting etc.  1988 90 Td5 NAS soft top

All RRC, DI, D2 and Defender 4HP 22 Boxes are the same length so the longer extension must be for a P38

Hi Linds,

both in the photos are for the LT230, short is V8, long is diesel,

the P38 one is different as the P38 transfer case has different bolt pattern, Dave
