Is there anyway to tell by looking at it, if the coverter is a lockup or not? I got a good deal on a TCI 2400, so i grabbed it without knowing if it had lockup.

I also have a converter out of a 2.8v6 700r... theoretically this converter would also stall higher as it was designed for use behind a weezy 2.8. this converter is definatly a lockup. Has anyone tryed a v6 converter on their modded V8s?

 

Ok, now I have been told that all 700r4s are lockup and all converters for them are lockup capable as well. Is this true? I remember reading recently that the early years 700s don't have lockup...

 

is there any part number on the TCI converter

 

74472
but that does not register on the TCI website, so i think I got screwed.

does anyone have access to GM PNs?

 

Not all R4 conveters are lockup, at least my aftermarket one isn't, I have a 12" ACT 2200 stall in my truck that is non locking, it was what I could afford at the time.
