WHAT TCI part # for turbo400 tranny?
#4
Sorry, I'm assuming you're going to be using a custom converter for this swap. I forgot that mine was built for an LS engine and I had to return the #754 for the #753. If you're using the old 400 converter with the short pilot, you will need the 399754 that comes with a spacer for the crankshaft. As well as the old GM big bolt pattern on this particular flexplate.
If your converter was built for the LS swap, it will most likely have an LS1 bolt pattern with an extended pilot shaft. This is where the 399753 comes in. Just confirm with whoever built it.
Here are some bolt patterns in case you need them.
TH350& LT1 10.750"
LS1 11.080"
TH400/4L80 - 11.500"

Im running a PCT converter. I dont have any type or shims in it at all. Just bolted it on. No spacers or anything. Im assuming this is what you mean by being built for the swap. SO i should be ok ordering up the 399753.
