hi guys had something weird happen to me yesterday i just had filled up my truck at the gas station. the station is right of the highway so when i was leaving there was a lot of traffic so i had to kinda gun it to get out and up to speed when i did so the tranny did something weird it would not shift out of 1st unless i completely let off the gas! thought this was kinda weird so i tried it again on a back road and it did the same thing it just causes the motor to bounce of rev limit till i let off and it switches gears... never floored it like that before so i have never noticed it in the past is this something to do with the tq management or could there be something wrong its a 03 with the 5.9 magnum thanks guys for taking the time to read this long post any help would be great thanks!

 

whatever you do, dont take it to me to get fixed!

 

I had a buick that did that until the tranny warmed up, It was a clogged filter. I wouldnt take the chance go get it checked out by a tech.

 

thanks guys i will do again just had it serviced like 6 months ago at my local dealership so kinda wondering if they even changed the filter or even did anything at all

 

That's just funny right there

I think it's a common problem on the older 45RFE transmissions.

 

does your truck have the 45RFE or the 48RE? i know my durango with the 5.9 had the 48RE, and bands needing to be adjusted were a common culprit to symptoms like that
