2000 F250 Trans Problems
Last weekend, I used the truck to put my boat in the lake. The truck is sitting at about a 30 degree angle when the boat is put in or taken out. I was able to put the boat in, and had to put it in first to pull away from the boat landing. But, when I took the boat out, I had no forward gears (of course it has to happen in a place where reverse, which works, does no good). I had to tow the truck home, because while first gear did come back if I shifted it directly, it didn't work in drive. The next morning I had no problem putting it in first gear to move it to a better spot to work on it.
The next day I replaced the transmission fluid and filter, including draining the torque converter. The fluid looked and smelled ok, and there were no chunks of anything in the pan. I should mention that the truck has 342000 miles on it - I bought it with 250,000 on it, and while the dealer claimed to have done all services on it when I bought it, it was time anyway.
I drove the truck over the past week, and everything worked, with the exception that it was hesitant to go into drive.
Last night I put my boat in again, and had the exact same thing happen: I was able to pull away from the boat landing incline after putting the boat in, but when I tried to pull away after loading the boat, I had no forward gears and had to tow it home. (Home is about 6 miles, low speeds, from the boat landing).
During the tows, I kept the engine running for lights and brakes, and to keep the transmission fluid circulating.
Today, I found that the transmission fluid was down. I don't believe it leaked out - every day this past week when I came home I slid a piece of cardboard under it to check for drips the next day, and there never were any. It took around a gallon more fluid today to bring it back up to the top of the HOT mark on the stick.
I checked the truck for codes and found none. I've long suspected that the Superchip that was in the truck when I bought it doesn't allow codes to be saved, so I hooked up the programmer and restored it to stock settings, and took it for a ride.
It starts with full positive engagement in first gear. It will not engage in second or drive. I was able to drive it at all speeds by starting in first then shifting it to drive. There is no slippage in first gear if it's shifted manually, but all gears, including first, slip in drive.
This truck does NOT have the external trans fluid filter.
