i recently had my converter "blueprinted" for my 440 powered mud drag truck. i was told that the converter would be made so that i could run high side of the t-case(1:1) have been running 2:1 low side. after i got it back the truck will only go about thirty feet in the high side, first gear 4.88 rear gears, and the engine wraps to near 7000rpm. the truck does not pull and shifting gears has no effect. with the truck in low side everything works fine. trans is manual valve body. could the converter be built to loose???
