I recently had the same issue with my tranny - would not shift out of first, despite re-starting and all.
Had the car towed back to my house.Re-started next day and still not shifting out of first.
The tranny had to be rebuilt!
Diagnosis : Clutch material within the tranny disintegrated and plugged up fluid channels.
Cost of rebuild : $1500
I did disconnect the kickdown switch (in case it was sticking) but still the same problem.You may want to do this check first before going any further.
