OK, I am sure this has been covered before but I am having trouble locating. I have this tranny in my 04 with almost 200k on it. it is have an intermittint issue with shifting between 3-4 and now it acts like reverse is loosing prime. I have changed the filter and fluid. Still no change. the matter seems to be getting worse. Sometimes it won't shift passed 3rd and reves up just fine. I can turn it off wait a min. and restart then everything is fine. I am thinking the VALVE BODY is going bad. But I have also read that there is a little rubber hose used in fluid pickup that could be bad causing the lose of prime. Are there any thoughts in this matter.
Since your transmission doesn't have a valve body I'm pretty sure that the valve body isn't the problem. I've never seen a little rubber hose inside the transmission. I have no idea what you mean by that.
Most likely it is a solenoid that is failing. It would probably be the direct solenoid since that one is used for fourth gear and reverse.

I know I can replace each of the soleniods, but not knowing exactly which 1 is the 4th gear/reverse I want to replace the whole thing. not only that its cheaper to. So what is the procedure to do this. Past the obvious. I know there are like 6-8 bolts holding the body in but after I remove them should it fall out or is there a wire harnes that needs to be disconnected and if so is this the same harnes on the outside of the tranny?
ty for your input.
