ACURA 4 SPEED COMPUTER SHIFTED TRANSAXLE DIAGNOSIS
If you have a computer shifted Acura with a shift complaint, eg. no upshift, stuck in 4th etc., you'll need to verify that the transaxle is capable of getting all four gears before taking the transaxle out of the car.
To do this you'll want to energize the shift solenoids with + 12V for each gear. Use the chart below to shift the transaxle.
If the transaxle shifts properly, the problem is not in the transaxle.
