I have a ZF4HP22, with 24 components, sat in my garage with V8 rover bell housing on it.
Previously a rangey box now converted to 2wd with a bmw 850 tail end, also it is modded with shift convertor, uprated stall, built by John LOvegrove of ATP Transmissions in Bristol, eveything there if interested.
This came from a xr4i, and will handle all day long what the rover can throw at it.
