ok guys, i am faced with a dilema. i am waiting to get my th400, is there a company that features some sorta lock for this tranny? i know PI has a lock up 5 disc converter for the th400, and speed inc. offers a lock-up th400, but are there other other companies that get the th400 more efficient?(besides GV)

 

TTT, need input please.

 

l just put a multi disk lock up in a customers th400 and l got it from yank. lt worked fine on my dyno. been out about a month haven't heard. lf you talk to mike at yank ask him about a super lite th 400 jk

 

cool,thanks for the info. anyone else.
