My Transmission is sticking

Need some help. Transmission won't shift until I get her up to 2500 rpm. Cruising at 25 mph in second gear its really revving. When coasting down hill and hit the throttle, it down shifts.

Also when tow/haul button is pressed while driving it slams into low gear. Really slams.

Re: My Transmission is sticking

Any recent changes or work done on the truck?
Have you had the transmission codes read out? If so, what are they?

Re: My Transmission is sticking

you most likely have an engine issue such as low boost that is causing a severe lack of power. this will delay your shifts in the way you are describing.

Re: My Transmission is sticking

Had EGR delete. No tunes. Had a Transmission shop diagnose it. They said the transmission was shifting on command. Then i had the guy who did the 4 injectors and egr delete drive while hooked up to computer. All the pressures seemed normal to him.

There were tunes as part of EGR delete. But it just seems odd that this started happening after the EGR delete was done.

The most concerning thing is when the Tow/Haul slams into gear. I have to come to complete stop before I apply it.

Re: My Transmission is sticking

I don't know about the low boost issue cuz she goes like a raped ape now. No lack of power at all.
