2002 Honda Civic EX with 207K miles. 1.7L and 4 sp OD A/T. Trans slips a little when shifting into OD or converter lock-up when ambient (outside) temps are 60 Deg (F) or lower. Slippage stops after car has warmed up or ambient temps rise. Other shifts seem fine. I am halfway through the 4-time drain and fill, but the slippage is still there. I am aware that it may just be the high mileage of the car, but I want to know if adding Lubeguard Red during the D&F will create more problems. Also using Castrol Import trans fluid in the D&F. Thanks.
