I have a 2002 ram 1500 slt 4 wheel drive. I been noticing that my truck will only shift somewhat normal when I slowly get it up to speed but when I need to pass or floor it from a dead stop it will wrap out to 4 grand rpms then shift then down shift again then shift up again then drive and shift normal. I been having this problem for about a week and need some insight on what to do I have already changed the oil and filter and pan and oil and filter was clean whats my next step.
