just done that i used a97 to 99vt 5lt turbo 700 flex plate to my t400 no worries it appeared to be slighty thicker metal so maybe stronger as well

Holden beefed up quite a bit of stuff in the VT including the block, so it makes sense that the flex plate could be heavier as well.
Also in my experience, VN through VT flex plates will interchange, with no problems.

You may have had a trimatic plate. I think the original TH400 plate is the same as the 4L60/4L60E one from VN-VSIII.

Hi all my van has a 350 chev T700 at the moment and the 350 needs recond but i have a turbo pattern 308 with a T350 so if i just take the T350 off will the 308 bolt straight up to the T700 with the same flex plate?Thanks .(the 350 will go back in when i rebuild the van but just after a quick fix to get it to the van nationals)
