just did rebuild seams to run good had question on trans. so we replaced it new fluid and convter.with no change. my problem is when I drop in gear it pulls off quick like it has no clutch. when you try to stop you have got to drop to N before you can bring it to a stop. I changed the brake switch thinking something electric but no change but my tail lights now work, What am I missing. I have looked at it so long that I have blinders on and seam not to be able to see the simple things. So I am turing to the firum for help. K

 

sounds like its sticking in over drive.....sounds like the OD apply solinoid is sticking in the apply position....but.....a valve body problem can also do the same thing.........does your cruise kick off when you hit the brakes?.....it might be bennificial to get a wiring diagram and start tracing some circuts.

 

if the od is in the trans we have changed in the first tran. but the change out tran does the samething so I am woundering what is the chance of 2 tran doing the same thing. what is up top of the motor that might be a problem? to the left of the throttle body is a pack of stuff that picks up vacum do not have any idea ow what you call this unit but could there be a problem hear? by the way we even have changed the vacum ball on the finder. thanks for the return help please send more info if you can. I have looked at this truck so long that even the simple things I am overlooking at this point, K
