I have been lurking here for a while and just hit my first problem in my swap. I am putting a 200-4r behind my 03' LQ4. I know they are many threads on this, but none have solved my problems. Here were my failures:

1) Stock 200 flex to LQ4 crank - NO - 2 pc seal flex to 1 pc seal block.

2)Ordered PAC-1399 from PACE - Wrong bolt pattern on flexplate to convertor bolts, do I have to elongate the holes? Also it comes with the GM spacer, does this go between the flex plate and crank?? If so would I have starter gear alignment issues?

3)I have heard I can't use the Hughes spacer (one between the flex and convertor snout that is not bolted in) for my truck motor flexplate. This is about the only thing I haven't tried and I don't want to have another mail order part to return.

4)00' camaro SS flexplate from a local auto parts store. Basically the sme looking flexplate as the one off my truck motor with the addition of a welded on metal piece about half way up the flexplate, that made me a little leary... Did I get pulled the wrong flexplate? I thought the 4l60 flex plates were suspose to be dished and this was the same as my truck flex (4l80)?

Without spending $250 on an aftermarket flex plate and probably having it still not work, what methods have worked when bolting an 03' LQ4 that originally came with a 4l80E to a 200-4r tranny??? Thanks

I am running a Hughes spacer standard 2002-2008 (just the dates of engines I have used) 6.0 curved flexplate and a stock matching 6.0 starter (these are cheap locally on car-part.com). Take a 168 tooth regular flexplate that has the right converter pattern and elongate the 6.0 flexplate holes to match.

I have a TCI flexplate and a PTC hybrid converter (half ls / half 200r4 ) no spacer is needed if you dont wanna use the expensive flexplate and your motor has the .400 factory spacer on the crank just take off the factory spacer and use the factory flat flexplate ( NOT CURVED) and you do have to oblong the holes in the flexplate to mount up the converter ,you'll need to use
a LS1 starter this way , call PTC and get a converter built mine was only 422.00 shipped and there a very good company and stand behind there product .. any more question just PM me

and also your going to have to clearence the bellhousing on the 200r4 a little bit the rear cover bolt hit and wont allow th trans to sit flush , not a big deal

What did you have to grind for clearance? Mine bolted up flush without any grinding.
