dana 300, difficult to shift, stock shifter

when i shift the case grinds and drops, i have the stock single shifter.

is this normal???????

once you are in a gear its great but its very hard to select and you have to be brutal when shifting.

would a twin stick setup have any bennifit???

Is there slop in the linkage? My 300 was very smooth shifting. What are you trying to shift into when it does it?

It grinds? are you trying to shift while driving? Your supposed to be stopped when shifting or a slow roll in neutral. I have problems shifting in and out of 4lo but if i get rolling in reverse then push in the clutch It will shift fine.

After putting a 4:1 kit in my Dana 300 and seeing how it goes together, it is easy to understand why they are hard to shift. With a single shifter you have to have the gear teeth on both output shafts lined up at the same time. This takes a bit of rolling around and turning the wheels to accomplish. I put twin sticks on mine and it is easy to shift now since each output shaft can be shifted separately. Twin stick is the only thing that is going to make a dana 300 easy to shift.

Twin Sticks....Mine did the same thing grinding and being generally unfriendly shifting. When I did my engine swap I went to twin sticks and it shifts super smooth now.

Same exact thing for me. Twin sticks rule!

The problem is with the auto and having it in neutral when shifting the transfer case. Try putting the trans in park first to stop the shafts from spinning. In neutral the output shaft of the trans is still spinning due to friction of the fluid and all the rotating components. This causes the input gear of the transfer case to spin, even though the transmission is in neutral. VERY common on 4x4 vehicles with automatic transmissions.

Should be fairly easy to do once you have all the parts collected up. Doing the mods to the shift rails to allow 2L/2H (F) - 2L/2H (R) - 4L/4H is about the only tough part. The external stuff is just bolting up the shifters and making sure they don't clash against each other which seems to involve some bending and tweaking.

As to the OP about the D300. Seems to me they are always balky since you are trying to line up two different spline shafts from a single input. My previous setup (151/SR4) would pop into 4H very well but it needed to be nudged a bit getting into 4L, sometimes would slip like silk, other times it would be a fight.

I bought the kit from Quadratec a few years ago and it went in pretty easily. If you are good with fabrication, I would make your own using 2 D300 shifter arms.

It's because of what I already said. When you shift into 4 wheel with one stick both of the sliding gears have to line up with their mating gears at the same time. You got lucky yesterday and they happened to be lined up when you shifted. This will rarely be the case. With twin sticks you can separately shift each side so the two sliding gears are not dependent on each other's positions. It is really a simple reason why the D300 is difficult to shift into 4 wheel.
