Have any one tried the factory tech performance valve body, from power surge performance on a E4OD trani?

 

You mean these?

Lots of satified owners... :-)

 

Yep, I just put a Factory Tech valve body in my '93 Lightning last week. VERY happy with it so far. I had a SuperChip in the truck (was installed by previous owner) which controlled the tranny, the valvebody does a much better jobs of making it shift quicker...but NOT harsher. Easy install as well.

 

Thanks for the response, do the tranni shift any firmer with the factory tech valve body or just quicker.
