GENIII/TH400 Guys Come In
 

I am swapping a LQ9 in my m1009 and I am going to keep the TH400. The way I understand it is I need the spacer for the hub of the converter to sit in and it goes between the flexplate and the converter? I assume there will be a gap between were the converter and flexplate bolt together? Do you use washers to take up that space? I called Hughes today to see what converter they recommend and he tried to tell me I would need their flexplate and spacer to make it work. Heck the flexplate and spacer is $200 plus the $297 for the converter. I would like to keep the cost down and use the stock flexplate. Thanks for any advice!!

I would not use washers. The spacer should be easy enough to find. It is about .4" thickness and has a step machined into it IIRC. Hit me up with a PM after Christmas, I have one but will not have time to ship to you till after Christmas.

I got a flexplate and hub adapter and new bolts from advanced adapters for 170. I have a 700r4 tho. I think they sell a th400 kit to.

I think there is a GM part from the 1999-2000 6.0l, flywheel I beleive that will work, I am looking for it.

I cant find it, here is one for $155.00 from a rep company.
