For some time now my 02 had been reving over 2500 rpms before it would shift to second under very light throttle, same with 2nd to third. Was told to replace solenoid so I ordered and electronics kit that included the solenoid, presure sensor and transducer. Worked great for about 5 minutes, shifted very smooth, then I stopped and it only went down to 3rd. I also installed a new speed sensor. So now it goes to third instead of first. It sounds like limp mode but when I shift by hand it goes to first and when I put it in drive it does't slam into third like limp mode. I repaced the new solenoid and that did'nt chang a thing. I got the speed sensor late and put that in today still no change. No codes any ideas?
