I am finishing my rebuild of my 200-4R and it was set up as a non-lockup trans but I’m converting it to lockup. My converter is a nonlockup type and I’ll be getting a new lockup converter for the trans. My question is can I use my non lockup converter in the trans just to do my pressure testing? Will it work or cause damage? If I can do this I’ll be able to check the trans sooner plus if something goes wrong I won’t potentially destroy a new expensive converter. Once all my pressure testing was done and good I’d slide the trans back and swap converters. Can this be done? Also, what are your recommendations for WOT lockup street strip converters, 2500 stall. I hear good stuff about PI and PTC. Any suggestions? Thanks in advance!
