i unplugged all the fuses and put them back on.. disconnected the battery and disconnected the main transmission plug.. does urs shift into 3rd and if it does does it sound like it neutralizes? mine would not shift at all it would stay in second.. it started to in second and stayed in second.. but after unplugging everything it went back to normal..

 

That's good stuff! Glad you got it under control... you might want to get a scanner on it to verify all systems are operating properly. Speed sensors and solenoids can operate intermittantly... keep an eye on it and let us know how it does!

Mine wont go into 3rd at all it take 1st if I down shift it but starts in second if I leave it in drive. It could be a fuse cause after my first pass at the track my truck wouldnt start anymore. Ended up bein a fuse along with some other fuses too. After that I made another pass wouldnt ever go into 3rd anymore.

 

Same exact **** mine was doing check all ur fuses.. disconnect the main Tranny plug etc... mine works perfect now....

 

Alright ill give it a shot tonight fingers crossed!
