I was wondering if you could help me. 2005 Dodge with 48re. The trucks not wanting to shift out of 1st gear unless the truck gets up to about 2300 rpms. The check engine light is on. I have codes p1753, and p1751. I've changed the ttva out with a new one and still have the same problem and code. After changing it, I did the ecm relearn thing with the key on for 30 seconds. I even tried taking the ecm fuse out with the key on and off sequence. Codes are still there. Do you have any suggestions? Thanks
