Hey all, My question is: is there some way to try to get a tranny to work without having to pull it back out of the truck? When I start it up and run the shifter through the gears, it does nothing. I made sure the shift lever moves correctly on the side of the tranny. Ive only tried it for a minute or so, should I try leaving it in gear longer (see below)? I have a 390 Ford with a C6 Transmission in my 49 Ford Pickup. I just got it to start after the engine and transmission were sitting for about 10 years. I used a B&M Frame mount tranny cooler that bolts to the frame beside the tranny. I didnt fill it with fluid before putting the lines on it. It did have mud dubber wasps that tried to burrow in and make a home in the transmission cooler lines and I dropped the pan, cleared the stoppage out, and changed out the filter while in there. It all looked clean inside the transmission with the pan off. They never made it in, just tried, and clogged up the little hole trying to get in with mud on them. I used the Air compressor and blew through the ports with the pan off and the air came into the valve body of the tranny just fine. It was really clean inside the tranny.....the fluid that came out of the pan did have a small section that had drawn moisture and looked kinda milky at the back right side of the pan when I pulled it but I assumed that was from when I washed it off before putting it into this truck. Other than that little area in the pan, the rest of the fluid looked like it had never sat. I do not have the heater hoses on the engine so I havent ran it for more than a few minutes at a time. I put 8 quarts of fluid in it so far and its reading half way up the dipstick (like its three quarts over full) after starting it up and going through the gears. It does nothing when I shift through any of the gears. It has the old vaccum module. but shouldnt it at least kick into gear wether the vaccum module is good or bad? Here is it starting up and you can see Im acutally shifting through the gears. It was 23 degrees outside. The fluid registers about half way up the dipstick. http://youtu.be/VPEDPoBQ_S0 What are your thoughts? Run it longer while in gear? I havent checked to see if there is fluid in the cooler yet.
