Automatic shifting problems !!!

[Boredoutteggy]

I have a 90 teggy and ever since I had it its had problems with shifting !its automatic !
It drives fine through 1st gear then shifts once and from there it stays in that one gear at high Rpms !
I changed the speedometer cable and both shift solenoids . What else could it be ?

did you check fluid level? Sounds like your tranny is done. get a used one. i would suggest finding one from a newer b18b since its more likely to have less miles or time to convert to manual

and if you do get one from a newer integra youll have to use your current torque converter.

I've had the car for 3 years and drove it how it is now . I mean reverse and all other gears are fine . Just doesnt wanna shift after first . Could it possibly just be a sensor or something simple ?
I have it at the tranny shop today So I should know . If so 5 speed conversion is my pick . Thanks for the help !
