Great thanks to all who answer!
May be i will buy a newer loyale or, even, legacy, and will swap from donor not only transmission but engine, tranny, ECU, TCU, etc...
That's why a smaller tunnel can be only one real issue for me. I'm digg into internet and not find any mention about another body used from 1988. Chassis models also not changed. I know earlier (before 84) models have different tunnel, but not sure about difference between 84 and 88 cars.It seems a bit illogically from point of unification I think. Also bigger tunnel can change some in salon or dashboard. Can anyone have some pictures of 3AT and 4AT transmissions, or better dimensions? Or experience of swap newer tranny into older body?
