I was wanting to get something like a PY3600 for a Rossler TH400. I have emailed many places on a lockup converter. ahat is the price of one of these? I want one so when i get a gear vendor it will be just like stock. SO who sales them how much. Any info.

 

A TH400 uses only a non-lockup converter. If you really want to keep the strength of the TH400 and have a lockup style converter...I'd suggest going with the 4L80E. It uses the same planetary setup as the TH400. It has the same gear ratios as the TH400 as well. It has both lockup and OD.

Yank makes a lock-up converter for the TH 400. Give them a call.
