Ive read many threads on the tranny and the 1-2 shift hunt and issues with 2nd gear. Thought i would give my scenario and see if someone can better pinpoint the issue.

Ive had the 1-2 shift hunt under low acceleration for 1 year and half or so and have just lived with it. In addition for some time now, while drving and stomping on the peddle, ther have been issues with it downshifting and not feeling like it was accelerating much. I think it would down shift into 2nd and would just rev high with not much go. Then, when it would shift into 3rd it would take off.

Now, it seems the 2nd gear has gotten much worse as it has the same symptoms but at normal acceleration. Just light throttle it goes into 2nd, but the truck doesnt accelerate much until it shifts into 3rd and then moves fine. IT also seems teh 1-2 shift hunt is much worse.

I was due for a fluid and filter change and the fluid didnt smell burned, i had some material on the magnet but im guessing it was from normal wear. ITs been 35,000 miles since last change. I filled back up with fluid and symptoms are eaxactly the same.

Before i go buy a shift kit, gov. sol. or sensor, valve body, torque conv. , i thought i would ask what people think. Im not too far from Floor it diesle so i guess i can drive down there to see what he thinks and suggestions. Oh and i have 92k miles

Thanks for any help.

 

KD band should have been adjusted when you supposedlly changed fluid. It is probablly burned out by now. The band cannot hold after makes 1 -2- upshift and tranny limps till can shift to direct. Then it goes.
If no threads are showing above jamb nut of KD adjsutment the band is worn out. Futher driving without repair will make the tranny overhaul more expensive.

 

happended to mine had to have the KD band adjusted

 

just went and adjusted teh KD band and what a world of difference that made. IT appears the band has worn and nut much threads above the nut. I suppose i can find a new band somehwere??? Thanks for the good diagnosis and help.
