I have an 86 truck similar to yours. It has a 4 speed over drive transmission. The Factory manual shows two sets of roller bearings on the counter shaft at each end, a sign of the 4 speed and 3 speed heavy duty transmissions. They got over drive by using third gear, with ratio changes for od, and fourth for third, one to one ratio as is normal for high in most transmissions. To make the shift pattern normal they reversed the lever on the side of the transmission so it points down ther by changing the motion of the shift lever. All this means nothing to your problem, but is some information. As for the shifter, I think they may be Hurst or a similar looking. There is a way to grease it too, I think the owners manual says as I don't see it in the transmission section of my manual.I think you put it in revrse and a grease fitting is then available under or around the shifter pointing to the left. To align the shifter and "time" the transmission to it you put a 1/4" rod ( about 2 1/2" long, through the shifter body and shift arms in the shifter, the pin goes left to right at the bottom of the shifter housing. This will put the shifter in the neutral position. Now with the transmission levers on the side of the transmission in the neutral position, you adjust the linkage rods to fit between the transmission arms and shifter arms.It will help if you take the boot and plastic thing the boot screws to off, this thing looks like metal. This might make the grease fitting easier to find too. I hope this helps, and you have the same setup as I am assuming. If you have any more questions you can post here or e mail me. As I said I have the factory book. Oh, the transmission calls for ATF for oil, I know this is a little different, but mine has had ATF in it for 190,000 miles and still sounds good. I don't think 890-90 would hurt them, buy it would make for slower shifting when cold. This is not the heavy duty 4sp that someone else refered to. That one has a creeper gear for low and no overdrive, it is a real truck transmission. Very heavy duty for a 1/2 ton but they were available too, my brother got two new dodges, with slant sixes, with this transmission, one was maybe a 75 and the other a 87. It is his 87 book that I have, he gave it to me when he recently sold his 87. It matches almost everything on my 86. I can give you the gear ratios if you are interested, they are listed on the book too.Yours has a 3.09 low and the truck transmission has a 6.68 low ratio. It is a New Process transmission
