Tranny Exchange

[buickdude]

I have a 67 Skylark that I have put a 430 in. It came out of a 67 Riviera. And it has the 300 Super Turbine tranny in it now. My question is what mods would I need to do when installing a 200r-4 tranny out of a 1984 LeSabre

These are the only few I can think of off the top of my head:
*move, possibly fabricate a cross- member.
*flexplate may need to be drilled.
*driveshaft will need to be cut
*MOST IMPORTANT, if you do actually do this swap you must make sure to wire the trans to lock up the torque converter! Do not just leave it unplugged, the 200r4, 700r4 need the converter to lock up in 3rd especially 4th because fluid flow is directly dependent in these clutches on it locking up.
