700R4 torque converter
I am looking for help with the 700R4 trans torque converter. The trans I am using came from a 1984 4x4 Blazer. I installed it in a 3/4 Chevy truck with a 4:11 rearend. The Blazer had a much higher rearend gear 2:08 maybe. When I drove the truck for the first time the tranny was in overdrive 20 feet out of the driveway. It shifts in and out of gear and has no power when you hit the gas. My feeling is that I need a higher stall converter. I am changing the gear ratio in the rearend to a 3:78 also. Am I on the right track or all wet?
