Hey guys, I'm installing a superior trans shift correction kit in my 04 Silverado. I'm using the kit along with sonnax pinless accumulator Pistons. Has anyone used the springs with a superior kit with the pinless style? (4l60e-lv) Thanks

 

Has anyone had experience with the superior shift correction kit only?

 

I did. I had one in my 06 silverado ss 4l65e. I didn't install it thought. My trans guy did while he was doing some other stuff. Did a vette servo and billet accumulator pistons and the trans ran great and felt strong for the next 25k miles before I sold the truck.

 

Thanks for the feedback. I went and ahead and installed the pinless accumulators with the superior kit and springs. I drove up the road a ways in it and it did great. Firm shifts, and even shifted into OD fine which was my problem in the first place. It was a chore to do it in the driveway, but you have to work with what you got!
