[12ht]

just signed up. can someone tell me will auto a440f transmision fit to the backof h55f 5speed gear box. have done a search but found nothing defenitive yes or no but found the gears alone should be intechangable and fit. doing a auto to manual gearbox swap on my l/c 60 12ht and thought i might aswell change if its out already. details off l/c are hj61 built 6/86 factory auto. 5speed gear box out of a hj60 sahara wagon build date 2/85. have all aus spec land cruiser a440f automatics got same hi/low ratio in transmision.have all aus spec l/c h55f got same hi/low ratios in transmision. reason for asking is i want to slow low ratio down a bit for 33'' tyres back to around as it was with 30'' tyres but leave hi ratio the same its perfect. thanks.
