Transmission problem
1991 Dodge Caravan 6 cyl Front Wheel Drive Automatic

I wrote earlier about my grand caravan not shifting . It will go in reverse , but not 1st , 3rd or 4th gears. It will only drive in 2nd gear and reverse. we have replaced the speed sensors . but problem still exsists. Also the check engine light is not lit .at the parts store they said they cant read codes if the light is not on there are no codes to read. ( any answers)???

On 91 an OBDII reader( that the part stores used) will not work
have to check with a repair shop for an old scanner tool and ask them to check the TCM codes for you
is it driving only in 2nd gear or when shift it goes into neutral
if stuck in 2nd have tranny solenoid checked
if not suspect tranny internal problem and need to be rebuilt
