I have a TH400 in my vehicle. I am building it for low end torque.
Is there an advantage to putting in a valve body, or high performance shift kit? I will not be towing with it, but just mild cruising.
Also, my TH400 is slow to get into gear first thing in the morning. Is there an adjustment? It happened all of a sudden. I changed the fluid three months ago and filter. I did just put a qt into the transmission. It seems to drip just under the hole in the bottom of the bellhousing.
