I don't know if this is a V6 specific issue or not, or if I am the only one to have this issue but this is whats going on. 0-50 my speedo works just fine. If I go any faster it stalls and goes all haywire. I tried replacing the cluster and it didn't do anything, I next thing I am going to try is the VSS. But after that I don't what I should change should it not work. Also another issue, if I should go 60+ My transmission feels like it wants to go into neutral or hold in third gear making my RPMs 3K or more. If I go to accelerate more than a lil nudge it does drop to neutral. Please tell me this is not an expensive tranny fix...Thank for the help.
