Had a small hole develope in transmission cooling line in radiator. Radiator and line was replaced. Transmission fluid changed. Saw no shavings. It is an automatic. Now to take off from stop you have to put gear shift in 1 and manually shift up after going. After getting on road shifts fine it just on take offs. Could this be a transmission solenoid issue? Thanks in advance for any input.
Are you sure you put the correct amount of fluid back in the transmission?
Remove the transmission fluid dipstick and check the color of the transmission fluid.
