th400 spacer question? Help Installing Now!
th400 spacer question? Help Installing Now! I am installing my TH400 today and the spacer that goes on the end of the torque converter does not fit in the crank all the way. Has anyone had this problem before.
It fits great over the converter. Is is not supposed to fit solid in the crank. Or should i ask it like this should it fit in there far enough that when I let go of it, it would stay in the crank? Cause mine does not. Any help is greatly appreciated.

with a hammer and a block of wood or a soft brass punch, just hammer it into the back of the crank, it will go right in
I could be wrong but the spacer needs to be installed after the flywheel. It should of come with some longer bolts as well. The idea is that it allows you to use a lt1 converter on and ls1 engine. The reason being is because the ls1 pilot is longer. Hope this helps. Vince

you are thinking of the gm style spacer, he has the hughes spacer, it is just a press fit sleeve that goes in the back of the crank
i have used them several times and they work great, just tap it into the back of the crank like a pilot bushing:

the small end goes into the back of the crank and the converter pilot rest's in the larger end when you put the trans up to the engine

Out of curiosity, why do you need the spacer at all? Doesn't the TC pilot fit in the back of the crank like mine does with out the spacer? My TCI flexplate came with that spacer, but it wasn't necessary with my Chance TC and TH400...
Edit: I'm gonna guess the TC had to be spaced out?

you need the spacer if you are using a stock th350/400/700r4 trans and converter with the stock flex plate
you can have a custom made converter with a longer pilot hub , then you wouldnt need the spacer
and for only $45 for the spacer it is a lot cheaper than having a custom made converter

I see. 
I have never used one of those before. I have always used the GM one. With that type of setup I would want to make sure that it is pressed straight and flush. Keep in mind that that is what provides the center line for the pump and converter. Thanks for the link so I could see what you guy's are playing with. Vince
