I have a 727 behind my 340. It has a TF-2 shift kit, an aux cooler in addition to the rad, and I swapped the converter to a turbo action 10" 3000 stall a couple of months ago. During hard launches, I occasionly get what feels like the trans slipping when it first gets into 3rd gear. It happens more readily the longer I drive, (heats up). If I let off the throttle a bit, it 'catches" and goes well from there. I'm thinking the clutches are slipping a bit and was wondering if increasing the line pressure would be a good remedy? Right now, pressure is adjusted per the TF-2 instructions. I felt this happening before the convertor swap but it is exagerated now with the higher stall. Any advice would be appreciated.

Thanks
