i just finished an article from offroad magazine, its the april 97 issue. The article is about premier performance. They make a valve body that takes the over drive feature and lets you use it to split first and second and second and third, making a four speed auto into a six speed auto, it only cost $895. The article didn't give a web site or address, phone and the article was talking about the GM 4L80E tranny, if anybody has heard of this company or has info about it, i would like to find out if they make a similar valve body for my E4OD tranny.

 

I searched for some information on them and didn’t come up with any thing for an E4OD.
But I did find there number, they don’t have a web site.
Here is their information call it and see if they make any thing for the E4OD:
