actually Dodgeman I like to think the L4N71B would be a better proposition as it has a lock up torque converter!
Good point. I rang an Auto Trans specialist in Sydney that had been recomended by several people that I spoke with & he recomended against the lockup version unless I was running EFI as these things use a small computer to control the lockup feature & they work better when used in conjunction with an ECU,... aparently.
I got the impression that the lockup model would need the original four speed bellhousing to make it all work properly & of course that wouldn't fit my engine.
He recomended that I use a Pintara as a donor vehicle & he said that he believed that the trans case would fit up to the 3N71A/B bellhousing, but he could not be sure, so I will get a spare bellhousing & hit the trans repair shops to find out for sure.
He said that the 4N71B trans case was longer, but the extention housing was shorter, leaving the whole trans at about the same length overall as the three speed.
He also opined that as long as I used the A15 in something as light as a 1200, it would probably work out just fine. The A14 would also be good, but not quite AS good.
