I have a twinsticked Dana 300 in my buggy. When I got it disengaging the rear was really easy but there was a big vibration that I thought was coming from the t-case. We rebuilt it and also installed the pills so it couldn't be 2low and 2high at the same time. I notched the rails as should be. When I put it back in the vibration was still there, but the bad part is that its really tough to disengage the rear axle. I have to push on it really hard for a good distance whereas before it was really easy. The twinsick function is almost unusable. I'm going to pull it out and put a lowmax kit in it and would like some advise on what I need to do so that it will shift easier like it used to be.

BTW - I did search for about an hour on here and google, but didn't have much luck. Feel free to link me to something I might of missed. Thanks!

my d300 doesn't like to shift when there is a lot of pressure on it, and that is hard to do when i am always engage at the axles, welded front and rear... sometimes its easy.. and a few others it's not.. i even run atf in mine.. but i feel it has everything to do with the pressure put on the gears....

I agree. I think it has more to do with the pressure on the grars. Mine is usually very easy but only a few times was it difficult. I was able to roll a bit to "free it up" then shifted fine.

I found that simply the more I used mine after I rebuilt it and stuffed it full of expensive LoMax parts - the easier it shifted. It kinda of broke it as far as shifting is concerned.

To the point where I am now, where it will disengage the front drive any time I am going down a steep grade. So a bit sloppy after 4 years of beatings.

I also have found that my 300 will not shift period anytime there is a load on the gears, even as "broke in" as it is.

bump the gas and it will shift like butter on the downside of the throttle....

Mine's always been that way since the twinstick... If the gears are loaded it won't shift if I wanted it to...

Yep, mine's always tough too. It's totally impossible to shift on an incline, even at the easy hills. With a crappy carb and the tempermental twin-stick, it's to the point where I have to remember to shift into 4low before I ever start a climb. If I don't, the carb will cutout in high and I have to roll down backwards with no power brakes or steering, then rock it back and forth a couple times to put it in low and try again. Sometimes my starter gets a good workout in order for me to have power going backwards down sketchy hills.

If someone does have a fix, I'd damn sure love to hear it.

Well I'm sure there is a fix because I didn't have this problem before the rebuild.

Mine is twin sticked with the tera low. I really only have one problem and that is popping out of gear going downhill in low range. It's the low range stick. LowMax sell a little ball that you can insert under the detent spring that balances the shifting with the other stick. It seems the d300 was made for single stick. (nooooooo)

Anyway, to shift from 4 low to 2 low I have to pull back the range stick, pull back the axle stick 1 notch, put the range stick back in low, then pull the axle stick back to rear wheel drive. I've done it so much that it seems normal to me.

The above about sums up my experience.
I have installed the shifter kit (little ball & spring) but doesn't seem to help any. It will still jump out of gear. Passenger keeps his foot on the shifter.

I have heard of some guys making modification to the shift rail but I haven't heard/seen/know how effective it was?

Shifting out of low can be a project on uneven ground ..... rocking, clutching, unlocking hubs, etc.

uhh, a Dana 300 doesn't have a range and axle stick. The twin sticks control the axles independently. H-N-L and H-N-L.


edit: If I wasn't moving, then I shifted the tranny into neutral to shift. If that didn't work then I'd pop it into reverse and then back to drive while lightly pressing on the t-case shifter. This took the bind off the gears and let me shift easily. You get used to it after a while.

well as with all 300's when you have pressure on the drive train it will not come out of gear... i just bump the gas a bit and pop ... it's out...
i have a tera low 4 to 1 kit and mine shifts great.... only problems I'm having is I keep breaking the input gear on the t/c.... going on #3 now.. they send me a new one everytime but I keep breaking it
