Trany problem Question

[Twinjracing]

I have a 96 F350 CC LB 4X4 with a E4OD This truck has had this problem for a bout three years now. That is one of the resons i sold it. I got it back from my brother and need to fix. The Back up only works when it wants to. If it's cold it works all the time (like first time that day you move it or after three or four hours) after that the temp out side playes with if the colder it is workes beter the warmer it is the less likely to work. But at any time it's a question. I had at trany rebilt 30,000 miles ago forwerd works great every trany shop says they haft to rebild at $1500-2000 no mater what don't want to rebild just need to get fixed so i can use as DD and get out of the car i'm driving.

Thanks

seems like a solenoid pack issue? a lot of places used reman solenoid packs VS new ones, the remans can mess up and act weird

[Twinjracing]

I was told by a few the solenoid pack didn't control that ?

I dont know, um maybe the reverse drum is bad? i really dont know a whole lot about transmissions, i let other people build mine

[Twinjracing]

Me to that's why i kind of want to know i don't want to spend money for some thing that should of been done right first time. But the shop yhat did mine is no longer there.

Well i dont know if thats a good sign or not, usually good shops dont go under

no answer for you but the tranny was going bad so you sold it to your own brother? thats awesome

I know he wanted from the day i got it. had two years never fixed any for the many small problems. The wife said it's time for it to go and back in my drive way. I wanted it back anyway i've missed it ever sence the new truck smell wore off my 08 and its true side came out.
