November 3, 20195 yr If you'd like some help, you will need to provide more details. I'd start by filling out your signature with details of your truck (year, model, mods, etc). And then let us know exactly how your transmission is behaving, has any work been done to it lately, etc.
November 3, 20195 yr Have you checked for trouble codes. It most likely has some. I just had issues with mine I doubted it was sensor issues but did turn out to be the Gov pressure sensor or transducer causing my issues. I replaced both and issues (2nd gear starts) went away. I'd have to do some research to find out possible causes for not shifting into 3 or 4th. Those are electronic shifts. So could be computer sensor related but dont discount mechanics fluid level bands, plugged filter etc.

I was trying to figure out how the OP could be any more vague and absent of any detail and I couldn't. He nailed it! Edited November 3, 20195 yr by Bullet

November 5, 20195 yr Yeah internal trans temp sensor will also cause that. Think its 2k ohms for your year cold. Or someone will correct that. Sign up for a membership and the 47RE book is available for download. There is a 8pin plug you can check that out on the trans. It's in the book.
Wont shift to 3rd or od
