Transmission symptoms no codes

Hi Mr. Honda,

It is normal for a transmission to spike to full line pressure in between shifts but the harsh engagement should be cushioned by the accumulators so that you have a smooth engagement and you don't feel the effects of higher line pressure.

If this engagement is exceptionally harsh then the decision is based on how far are you willing to go? Once you open the unit to replace/repair the valve body, accumulators and shift solenoids, you should perform an air check on the clutch packs. If you find an issue there then you will need to perform a complete rebuild.

In my opinion, once you need to go into the unit and you are close to 200,000 miles and it has not just been rebuilt, it is always a good idea to just do a complete rebuild or replace the unit. A transmission is not one of those items that you want to try and make band aid repairs once you open it up. It is too much of a hassle and once you change on thing, most likely something else is not going to function the same causing you to go back in because you will not know that until you get it back together and drive it. I have learned this from experience.

If you want to repair any of it let me know and I can send you the procedure but from the sound of it you already have access to Alldata to pull it.

Please let me know if there is anything else you need. Thanks

Here is an article that will give some other ideas as well that I may have missed.

Okay. Doing a valve body and shift kit may not address a harsh engagement. In fact, the shift kit may make it worse. It is probably worth a try but I would count it as a bonus if it addresses any shifting issues.

Let me know how I can assist and I will be happy to help. Thanks
