I just got done reinstalling my new tranny after I took it out and had the input sprag replaced. Before I had the sprag replaced, any time I was in 0D going more then about 45mph and I put the pedal to the floor, it would rev up to about 4500 then bang into gear. It would shift fine if I did it manually. But now after the new sprag, it is doing the same exact thing. I don't suppose a bad TC would cause something like this? Is the new sprag bad too? Any help would be great.

i'm going to venture to say that, the revving up and "banging", into gear is probably what broke the sprag in the first place, and will probably break it again

 

then what would make it rev up in the first place?
