towtruckdriver88

Hi I'm new to the site and have a question about the E4OD in my 1990 F-150. Has the 5.8 and only 84000 original miles. It doesn't want the shift automatically into second, it will rev to 3500 rpm and go straight to 3rd. However if I shift manually to 2nd, it does fine. I have replaced the ECM and still does the same thing
Any advise? Thanks.
