I found out that Ligier Js1 Le Mans car used "modified" Citroen transmission!
For the 1970 Tour de France, Ligier prepared two JS1s, both powered by a Ford V6 engine. The first car was equipped with a 2.4 litre Weslake prepared engine and the other with the regular 2.6 litre version also found in the Ford Capri. To make room for the bigger engines, the chassis was lengthened considerably. The Hewland gearbox used together with the Cosworth engines did not fit the V6s and was replaced by a Citroën SM derived five-speed transaxle.
Please correct me, if I'm wrong here.
I'm not an expert on Fords, but I think that Ford 26M 60º V6 crank rotates clockwise. Ford Cologne V6 engine - Ford Wiki
Looking at the engine from the front, Ford 26M would have the same crank rotation direction as our Esprit. Therefore, I expect, they had the same problems as we do, i.e. box and CWP running backwards**!
I heard, that the internal gears in the Ligier box were "reverse" cut to mitigate the pinion shaft force vector toward the rear bearing.
I'd like to learn more about this tranny.
