Good Morning all.

I have a question concerning my 03 F250 V10 auto. I have been running the Delta chip since June of 03. It has increased the firmness of tranny shifts. I am changing tranny fluid soon and am considering installing the sonnax valve and t. springs.

Would this be "too much" with the chip? Harmful mechanically/longevity wise?

As always, thanks for your help Ken.

The shift might end up being too harse (for most people). I recommend sending the chip back to get the line pressure increase at shifts removed.

 

Too harsh mechanically or for personal preference?

Mostly city/empty driving on 35' tires. Used to drive mustangs/cobras as daily drivers and I am looking for a little better performance to make me smile. Will be going to 8" lift, 37"-38" tires, and regearing within the next year hopefully.

I am willing to install the valve/springs if it will not do mechanical harm with the chip running. I can always take them out if I don't like it.

Have you reprogrammed trucks with the valve/springs installed to find the sweet spot?

Sorry about the slow reply, working too much.

Thanks.

J.
