The other day, when starting out for the first time I had a problem with the car apparently not shifting into second so when the turbo kicked in the rpm's went to @ 3000 with no increase in power to drivetrain. Once the car was fully warmed up I had no further problem. Where to I start to find out what the problem is? The tranny otherwise has no apparent slippage, and this only happens sporadically on the first start of the day.
