ok, My 04 if i am driving about 80km or more up to 120km (any where in that range) and step on er it shifts back to 3rd hard, then slowly goes back into OD... this is the only truck i have ever seen do this all my buddys don't do this they just gradualy pick up to speed without shifting.. or truck has about 164K on it

Did this sence i bought it.

 

any one.?"?

 

My 05 shifts into 3'd more easily than my 03 did when I really step on it at highway speeds.(Like a passing gear.) You had to really step on it with the 03. It's not a problem- just different. With my brother's 03 SO you really could'nt get it to shift into 3'd, which wasn't good if you wanted to pass quickly.

 

Your getting what I call a dog hunting. I take it your have a 4 speed auto 47 or 48re. A good tranny shop will be able to setup your valve body to stop this. It is caused by spring pressure/gov. pressure sensor(gps). The gps says one thing an the spring load does another. It's a pain I know mine (48re) did that from the day I bought it untill I had mine custom built for the job I was doing. When mine was doing it I had to either power through it or just slow down one. Hope this will help you.
