2nd to 3rd slip on 89 trans
What would cause the trans to slip from 2nd to 3rd. Its kinda like a delayed shift. The revs. increase and if then shifts, just a little slip (i guess) but sometimes when the car is cold the trans is stuck in 2nd. I have drained and refiled the trans with honda atf 3 times and cleaned the solenoids about 6-7 times. before I did that the car would only shift from 1st to 4th. I now just want to get rid of this problem. Could it be a clutch pack or something, trans fluid pressure? and should I ad a filter? as there always seems to be debris on the solenoid screens even after a week.
P.S. will a 90 trans work in a 89 I know the tcu is different.
