Wayne, I have a 700R4 behind a built 421 tripower in my 64 Tempest. I am using a lockup converter w/manual switch because it was highly recommended by Bowtie Overdrives, which is where the trans came from. Their reasoning was because of heat created by converter slippage in overdrive. My converter only locks in overdrive and I do see a substantial difference in trans temp when I drive alot in third versus in OD. BTO says the trans temp should not be much above 150 for extended periods. The only time I see higher temps is on hot days when I am not getting into OD/lockup mode. Hope this helps. Mike Holleman
