When cold transmission shifts hard. Warmed up it is fine
So I bought an i35 recently.I test drove it when the car had been driven home from the guys work so it was nice and warmed up. So I didnt notice the transmission issue since it only happens when it is cold.
When cold, the shift from 1 to 2 is hard. From 2 to 3 it seems to rev and slip into 3rd. 3rd to 4th is fine.
When warmed up, it seems to shift fine. I have drained and re-added fluid 4 time (16 quarts) to dilute and flush the old fluid out. Fluid was pretty black. I would drain, measure, and refill. Go drive 5 miles. Come back and repeat. I filtered all the old fluid and didnt see any metal in the filter. So that is good. I bought 8 more quarts today to drain twice more. By that point, the fluid should be thoroughly changed out. I am using Castrol Import Multi Vehicle transmission fluid.
I just bought a new seal and filter, 8 more quarts of of oil, and will be dropping the pan. I couldnt find the self sealing screws locally, so I will be using some blue permatex thread sealer.
Any ideas what might be causing this behavior?
