vibration in over drive

[optimus]

this is an 02 F250 7.3 with 175k miles. The engine starts fine, idles fine, has plenty of power and no smoke but when the truck shifts into overdrive it vibrates the whole truck. If i accelerate and it down shifts vibration stops till it shifts back to OD. I have already tested everything with AE the Injector driver module was throwing codes so i changed it out it's testing fine now. #8 injector is showing poor contribution have ordered a replacement for that but as the engine has plenty of power I'm not sure that it's actually bad. I'm wondering if the torque converter might be failing and if there is any way to test it.

also my overdrive on/off button doesn't work I don't think it would cause a problem like this but I'm going to change the shifter anyway to get it working.

any help is greatly appreciated.

PS. before anyone point's it out i know this is posted in the motor problems thread. i did this because i know that a lot of motor problems can mimic other issues. and i want to make sure the engine guys get to take a look at this.

never mind I fixed it #6 injector was failing and UVCWH was bad on drivers side changed and all is good
