What causes reverse not to work until engine warms up in cold weather?
I was told fluid drains out of the torque converter(overnight) due to a bad inner seal when cold,once the car warms up and fluid is pumed back in the converter it operates fine.I’m going to try a additive to swell the seals,my olds acheiva(96)has over 200,000 and I’m going to try this before I drop the big bucks down.This car runs great all day but takes ten minutes to warm up in the morning,before it shifts fine
