this / is more toward winfred...i have a 1990 535i that i redid per your forum from before when i put it back together i did the hard start to clear the computers , then all it does in the "e" mode is saty in 1 gear , if i switch it to "m" mode i can up and downshift with the shifter , is is a computer failure where i need to replace the tcm?

thanks in advance slup
