I swapped out my M-21 4 spd for a 700R4. It's a shoulder and age issue. Anyway, I routed the cooler, a B&M 14000 BTU, in front of the radiator. The lines run up over the right front fender and down to the cooler. Everything seems to be ok but checking the fluid level is confusing. When the fluid is cold, the dip stick shows the level to be way too high. I assume this is because the lines and cooler are higher than the sump and the fluid weeps down into the trans case. When the fluid is hot, the dip stick only shows fluid at the tip of the dip stick. Now here's the question: I think I should add fluid while the car is hot, engine running until the level shows it to be at the full position on the dip stick and forget about what the cold level shows or is there some other point I should be concerned with? The car shifts from first to second ok, but the 2nd to 3rd is soft. Any thoughts?
