While I'm driving at highway speeds the tranny suddenally shifts into neutral. It will last for 5 second then go back into gear. I do not beat on it at all and I should mention it has a stage 4 suncoast kit in it. Any ideas.

thanks

Very basic, but are you sure fluid is full?

How long ago did you install the tranny kit? When I put mine in, I had to reset the "TAPS" which has to do with the shifting of the tranny. I think they call it a flair up. I just drove it more and more and Ally re-learned how to shift. Now its fine probally put 1k on it now and not easy miles.... Mine was felt like it went into neutral but then it would bang into gear. Kinda felt like I limped the tranny not I ever did before. But I was told by a "friend" thats what it felt like.:)

Fluid level is correct, currently at the dealer for a week with no answers. Was hopeing someone has had this problem and resolved it.

Had the stage 4 for over 2 years with no problems. This just started two months ago.
