97 4T65E-HD rebuild and questions

Started rebuilding my 4T65E-HD from a 97 GTP, has been quite a bit of fun! Found the culprit for metal slivers in the filter, which is a sigh of relief. So far, everything has checked out for visual inspection, minus one bearing (the culprit). No biggie, only a 7$ part.

I'm gonna be taking the trans to a place to get all of the exposed covers and the case steam cleaned so it's nice and shiny :)

Just had one question; this transmission is going into an 02 GT. From visual inspection, it looks like the trans in there has the same PNP switch that the 97 one does, so I don't think that will be an issue. What I am wondering though is will the torque converter bolt up to the flex plate on the L36 ok? I'll make all the modifications necessary while it's in pieces so it is easier.

Also, my understanding is the must-upgrade parts for these trannies that doesn't come in a TEP performance rebuild kit are the IS and gear/chains. Is there anything else I should consider upgrading? Can't afford a torsen (unfortunately lol).

Will post pics soon too for funsies.
 


Of these four, which would you do?
1) Screw it, pull the GT motor and throw the L67 from the 98 in there so they bolt up fine and call it a day
2) Put the L67 flexplate on the L36 (don't know if this is possible)
3) Use the torque converter from the 4T65E currently in the 02 (Also don't know if this is possible)
4) The BillBoost way: <Insert here>
 
2 or 3.. take your choice. The GT will have a higher stall and will be lighter...aka more power faster. Flex will bolt right up. BTW while you are there.. change that rear engine cover..cause it's probably seeping already.
 
FWIW I've had all of the combo's.

Currently have a NA on SC trans with SC converter
Had SC on NA gears and NA converter
 


Noooo

First off.. look at the flex. Some are dual drilled. 245mm and 258mm. Old days.. SC was 258 only drilled and NA was only 245mm drilled. Mix and match either the flex or converter unless your flex is dual drilled like the newer cars.
