So here is my next question or 2. 1st in a stock 4L60E tranny with a corvette servo; do I need the shallow or deep tranny filter? And What tranny fluid? I seen the Dex VI, but what I read on the back of the bottle was for 2005 and up. Will this work in my 04? I read the other thread about Tranny Fluid and it ended with Dex IV or VI. So will the Dex VI give the same affects as back in the days when people used Type F tranny fluid instead for better firmness in the shifting to avoid the slippage?
