Well i had my transmission rebuilt.. built all clutches ect but got a stock Stall
and when it locks up it fell really bad and when accelerating a little bit it shaked the truck felt like my tranny was going to fall like shutter.. so i took it back and got another stock stall since i didnt have more money for a aftermarket one.. and the shutter and all that didnt stop but felt way less but now sometimes it locks up at like 40-45 and sometimes it doesnt i can got up to 60-70 regular driving and doesnt lock up until a while later.. and my rpms go up more than average.. and sometimes it locks up right away...
What could it be? anyone have any idea is the Stall bad? should i change it..
i have a yank st3500 but havent put it on... could it be something electrical or other than the stall?

Any help is appreciated greatly

You posted the same problem almost 4 months ago. It sound's like you have issues with your transmission. Maybe its time to look some were else...

 

Yhea i know but he checked it and everything was fixed but know it doesnt want to lock from time to time.. i just think its the stall because the stall i got is rebuilt.. the one right now
