Has anybody ever thought about the possibilty of installing a lock up converter on the 518? I understand that the bell housing won't accomodate the extra length of the converter with lock up clutches but somebody could machine an inexpensive adapter to give you the length you need. Then you could have a switch to engage and disengage it. I suppose it would just be easier to just swap in a 47rh though. I guess I'm just brainstorming.

 

Swap in the 47RH like you said,you couldnt do the work to make it lockup, without a total redesign,youd need a new valve body with the oiling circuit,and input drum/shaft/front pump,+ many other things would need to be custom made.Dropping in a 47RH is too easy not to do it,if you want lockup that bad.

 

True, I forgot about the oiling circuit that would be needed. I guess a real good converter is the ticket since I already got money into clutches and steels.
