Any thoughts on how difficult it'd be to convert a TD5 disco II to auto box from manual
1) using the 'box from another TD5?2) using the 'box from a classic rangie or disco I?
I'm aware that 2) would need modifications to connect the kickdown cable, however the speeds/gear ratios look about right, comparing with the manual TD5: 5th gear is about 1900 revs at 50 mph, which is what the RR shows at lockup point on the ZF4HP22, and the TD5 will pull quite well at 1900 revs upwards.
In both cases would need a flexplate, would the flexplate from a genuine TD5 auto engine mate with the 4HP22 torque converter?
