700R4's: what years to avoid
my brother has R4 out of 87 vette along with a TH400 that he's trying to decide which to use behind the Weiland blown, vortec 350 he's dropping in a 86 IROC project he's doing. i'm trying to convince him use the TH400 and trade me for a TH350 out of an 80-81. i've heard the "earlier" 700R4's had problems but cant remember the yr of the design change that made them better.
thanks

No amount of anythng will make up for the inherently weak/overheating due to lack of lubrication/oil flow of the 3/4 clutch pack....
heard all sorts of excuses, and seen a LONG list of fixes gotta be about 5-6 solutions out there still....
use the 400 and put in a Trans Go shift kit....

Check this websight out. There is a ton of good parts info on the 700R4 and other transmissions.
