hello welcome to the site

this is a internal transmission failure and the only solution is replacing the transmission.

this is what American honda has us follow.

this is a code for shift solenoids

A/T Solenoid Replacement


NOTE: This article applies to '01-03 3.2CLs,

'01-04 MDXs, '02-04 RSXs, '99-03 3.2TLs,

'04 TLs, and '04 TSXs.

The diagnostic procedures in our service manuals

were written before we had solenoid replacement


To cut down on unnecessary solenoid

replacement, don't replace solenoids if any of

these criteria are met:

  • The odometer has more than 20,000 miles.
  • The vehicle has a reman A/T.
  • The ATF is contaminated with friction material

or metal.

  • The axle seals are leaking or the differential

carrier bearings are loose.
