I'm having trouble getting my WD into reverse in this cold weather. In the past, she's always been a little hard to shift when sitting still and very cold, but yesterday I wasn't able to get her into reverse at all even after starting her up and getting temps up! I was able to shift through all gears but reverse. Anybody have any suggestions?
Thanks,
KC/WD

| First, a few questions. Does the lever go into the reverse slot, or can't you get the lever into the slot? Have you checked the transmission oil? Do you know what grade it is? |

Yes, I can feel the shifter slide into the reverse slot slightly. Trainy fluid is hvy duty hydro fluid or should I say molases.

You might have a bend shifter fork. I might suggest changing the trans fluid. If it's that thick, it probably won't move until it gets warmed up.
It's hard to say what the problem with shifting is. What I might suggest is looking for a tractor salvage dealer and get a used shifter tower, which would include the shift forks. While you have the tower off, try sliding the gears together and see if they mesh properly.

| KC/WD, but just a word of warning - it can be tricky to get the tower back on, with the forks properly lined up with transmission gears, so have it in a place you can properly work on it, like a shed, shop or garage. I found it easier to put the tower back on with the shifter positioned as if in gear (I can't remember if it was first gear or reverse - maybe someone can remind me on this). That is because if you put it back on in neutral, the slot on the gear is hidden or in a difficult position. You can tell if the shifter fork is bent if the contact portion of the fork is severely worn on one side. |

Put it in either 2nd gear or reverse to remove the tower. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

| Could be the rod(s) that the shift forks are attached to, but I think the shift fork is bent or bad. Don't take the dent balls out from the rods, because I hear they are a bugger to put back. |

YAY!!!! Well the ol girl decided to cooperate this evening. As soon as I got home from work, I had to start her up and bring up to temp, then she slipped right into reverse! Well Heck, I had to drive her around the pasture then until I couldn't feel my fingers anymore. Sure is cold out there. Thanks to all for your input, and HAPPY HOLIDAYS!!!!

If it was mine, I would get it warmed up( inside a shed if possible) and drain the fluid. It could very well have water in the bottom freezing up, which is kinda hard on tranny cases. Replace the fluid with 20W hytan fluid and you will be good to go at 20 below.

I think I will drain it down this wkd and replace with a lighter weight fluid. Thanks for the recommendations! NOW, on this '49 model WD, is there another fill port for the transmission other than the hydraulic fill cap? |

Look on the side of the transmission between the transmission and the frame rail on the left side. There are two square head pipe plugs. Those are your transmission fill ports. It helps to have a long neck funnel to fill them. You only have to fill one of them, they are connected in the gear case.

And aren't there 3 different drain plugs to get everything drained out?

If I remember right the transmission and hydraulic are separate. One drain plug is the hydraulic. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

| The most important drain will be the one on the bottom of the pto housing if there is ice, the trans drain is up in the drawbar area and will be covered with grease-- you will need a good lite and a scrapper to find it!!! |
