You recently took your car in for a tune up transmission service your transmission was leaking a week later the engine light came on and wouldn't shift out of second after it was fixed whats wrong?

If they worked on the transmission there should a warranty period.
Call them, then take it back and make them fix it. Good Luck and Remember.
Change Your Mind, Not Your Oil.
Use the First In Synthetic Motor Oil's.
See My Bio For more information. If the transmission is leaking and it won't shift, try checking the transmission pan and filter. They might not have replaced the gasket or filter.
