and the year car? they are diff. the years. but yours is 96+ i can tell that.
your profile and sig are zippo.
how did you get code.?
740 is std,.Federal code for TCC failure. my fsm for 96 shows not such code, only 773,771 9 where did you get this and how.
TCC is directly driven by TCm (no relay in 1996) im guessing on year.
the tcc solenoid can be replaced tranny in car.
TCC locks up on both 3rd and 4th gears on 4sp. 96.
book says, problem can be engine or tranny , is takes careful diagnosis.
in normal shift mode (not power switch)
tcc happens
in 3rd gear at 45mph and if that happens.
in 4th it happens at 58mph.
but all this depend on motor load and throttle position and is quite complex.
i can send the graphs to you and you will be more confused.
