Recently I am having a problem with my tranny not shifting properly from second into third. Tranny is a suncoast stage 4 with a 1056 converter. The truck seems to shift perfectly when it is cold, but once the tranny temp heats up, it feels like the truck loads up in second and then shifts hard into third.
Checked the fluid levels and they are all fine. Run all amsoil synthetics.
I also have a clunk when I shift the truck from park into reverse, so I imagine it's the u joints which I will be changing this weekend. Somehow I think my tranny shift problems go beyond the u joints.
Tried several different tunes and it makes no difference.
This is starting to irritate me.
Any ideas?
