Can someone on this thread comment on how to check the level? Should the vehicle be in Drive or Park? I put 8 qtrs in after service and added a tranny cooler. When I added the tranny cooler it drained the cooler in the radiator. So, I believe it is still about 1pt or so low but don't want to overfill. The level is about halfway up the dipstick when it is in Park and at operating temp. The dipstick indicates it should be higher. Please help. Thanks.
