TH350 w/ transbrake???

I have a TH 350 with a transbrke, I bought it this way and am not familiar with transbrakes or transmissions for that matter, The guy said it has everything TCI makes for a th350 in it for whatever thats worth, problem is it won't disengage,, I have a button to press for reverse and it sticks, I have no 1st gear when it does this and I have removed the selinoid and blew it out real good and wd40'd it ,, then I pulled the shaft that goes in the tranny out and cleaned it good and reinstalled it , it will pop in and out all day long after I do this until I crank it and use it then it sticks, I can manually pull the selinoid out but I get no spring return when I do this like the shaft in the tranny is stuck , any suggestions, or should I just have someone put a manuel valve body in and get rid of it. If I do this any suggestions on a reverse shift manuel valve body and costs ,, so I can have an idea if I am getting the shaft,,

there should be a spring in front of the valve that solenoid pushes for the activation of the trans brake.

If there is a spring and every thing sticks each time you use the tranny , the tranny may be coming apart and sticking the parts.

Mayb the converter is putting metal into the works and sticking stuff

Have you called TCI for ideas?

Mayb they can fax some instruction sheets to you to help figure out the problem
Dont worry how old you are... it is the mileage on your body that adds up.

RE transbrake

It does have a return spring, I pulled it apart and there were no obvious metal inthe fluid, I stretched the spring to try and get some more return but it still sticks, I will have it checked by a professional , I was just wondering if you guys had any ideas,, I sure hope it isn't coming apart, it has a 3500 stall in it ,
